Hey there, I hope you are having a good day. Printed circuit boards (PCBs) are a popular topic in the electronic world and we also know that PCBs have revolutionized circuits. They not only provide a solid base but the material used in the PCBs helps the circuit to function properly by protecting the circuit from factors like external radiation. These are present in different materials that divide the working, stability, and reliability of the circuit. In recent years, there has been a significant change in the types and strength of PCBs and this depends on the materials used in the manufacturing of these boards. We are interested in studying the advanced materials used in the manufacturing of PCBs and knowing the right type of material for the right circuit.
In this article, we’ll start from the basic introduction of the advanced material and will try to understand why it is better to replace the traditional material with the advanced one. After that, we’ll see some important categories of the advanced materials used in the production of PCBs that are important to meet the needs of the latest technologies.
Before going forward, let me first tell you where you manufacture your PCBs with these materials. PCBWay Manufacturing House provides almost all of these materials for PCB manufacturing. PCWay provides the best services when it comes to PCB designing. I personally use PCBWay for all my PCB orders and always get the best results.
The transformation of PCBs in recent years is because of the high quality and advanced materials used in manufacturing and this not only has improved the life span of the PCBs but also has a major impact on the circuit performance. The advanced materials are referred to as:
"The advanced materials for PCB manufacturing are the new material or the improved existing materials used in the manufacturing and design of the latest PCBs that help to meet the requirements of the advanced PCBs."
With the advancement in technologies, there is a requirement for faster, smaller, and more efficient electronics, and that in return, has enhanced the need for advanced PCBs. These requirements are fulfilled by using the advanced and more efficient material that helps to meet the need of the time. These materials are responsible for innovating the PCBs and these are not only the trend but are the essentials that are required to meet the requirements of contemporary electronic applications.
The advanced materials are better in performance and provide high-speed data transmission from one end to the other which is the main focus of the advanced digital electronic equipment.
Here is a list of almost all the important advanced materials that are extensively used in the PCBs nowadays and play a crucial role in the improvements of the PCB industry:
The traditional material is not able to overcome the advanced problems and boundaries of the bandwidth. The high-frequency circuits are introduced in the market that perform complex duties and these circuits are successful only when high-frequency PCBs are used. For this purpose, high-speed laminates are used for the manufacturing and design of the PCB. these cutting-edge laminates are the new generation of high-frequency materials for PCBs tailored for high-frequency applications.
These laminates have an exceptionally low dielectric constant (Dk) that ensures minimal signal distortion. This property makes the PCB capable of dealing with the speed of light making the circuit work faster and better to match the new trends and requirements of the technology.
The minimal signal loss helps this material to provide another feature to PCB which is the negligible dissipation factor (Df). It maintains the signal integrity and provides low heat dissipation. One must be kept in mind that it results in efficiently dealing with the heat problems of the circuit.
The thermal stability of the high-frequency laminates is a plus point that helps to achieve the advanced level outputs from the circuit. These laminates have the physical properties to bear the high temperature without causing any change in their shape.
The following are suitable examples that are widely used in PCBs:
Rogers RO4000 series
Taconic CERFREE
PTFE (Polytetrafluoroethylene)
FR-4
Isola Isola-Tate FR-408
LCP (Liquid Crystal Polymer)
The metal core PCBs (also known as the MCPCBs) are the specialized PCBs that has the metal base as the substrate. The most common metal-based PCB types are listed below:
Aluminum
Copper
Steel alloy
Out of these aluminium-based PCBs are the most cost-effective. One evidence of this statement is, that it has high heat resistance therefore, such PCBs have a long life. Hence, the low heat dissipation results in the better performance of the circuit for a long time.
On the other hand, if the user wants high performance then the copper-based MCPCBs are a better option than the previous one. Copper is considered one of the most reliable conductors because of the physical arrangement of its atoms therefore, using it in the PCB is the best way to get the highest performance. This is the most commonly used material for the PCBs but it is more expensive the the aluminum PCBs.
Another important metal in regard is steel which is harder than the other two options mentioned before. Because of the tightly packed structure, this type of PCB has less conductivity but the plus point is, that these have excellent heat dissipation.
As a result, the specific type of the metal core PCB is used for the specific type of the circuit by keeping the thermal and other characteristics of the PCBs. These types of materials are used in PCBs because they have features like heat dissipation, less distortion, good dimensional stability, etc.
The flexible PCBs are one of the most trending type of PCBs that have the ability to make space in any type of the circuit and does not cause any major performance change. The advanced technology has made the circuit small and more flexible, therefore, there is a need for the PCB that is flexible and can bear the load of the high calculation and processing. These are made with lightweight, thin, and flexible materials and lead to a high range of applications in all types of circuits.
These PCBs are made on different scales of size and thickness and can be bent like a rubber therefore, are considered the ideal PCBs for wearables and other such technologies. The most commonly used flexible materials for PCBs are
LCP (Liquid Crystal Polymer)
PEN (Polyethylene naphthalate)
PET (Polyethylene Terephthalate)
PI (Polyimide)
PTFE (Polytetrafluoroethylene)
Flexural FR-4
Coverlay films (PI, PET, etc.)
Metal foil (copper, aluminium)
Adhesives (acrylic, epoxy)
Hence in this way, we have seen different type of advanced materials that are used in the PCBs and are making them more efficient and up to date. We started with the basic introduction of the advanced materials in the PCBs and then we understood different types of the advanced material that is revolutionising the PCB industry. The high-speed laminates, metal core PCB, and the flexible materials in the PCBs are important materials in this regard. If you know other such materials that are most common and suitable for advanced PCBs then share with us through the comment section.

Hello learners! Welcome to the introduction of the round PCBs, where we are going to discuss the round PCBs in detail. This is specially designed for articles for beginners as well as for intermediate skills in printed circuit boards. PCBs are the backbone of any circuit, and it is crucial to understand the type and application of the circuit and its PCB in detail before starting to work on it.
If you are going to buy crucial products like PCBs, always choose the best option that has positive reviews and a great experience. The best option for this is PCBWay.com, which has a great variety of PCBs, electronic components, equipment, and services. They have a vast variety of PCB services that range from high-speed PCBs to optical module PCBs, semiconductor tests, aerospace PCB circuit boards, and many other fields in different shapes, including round PCBs.

In this article, we’ll see the basic introduction of round PCBs. We’ll see the definition of round PCBs and understand how they are different from the other shapes. After that, we’ll see its manufacturing in detail and will see different phases of manufacturing. We’ll also have a look at their application. Let’s start learning.
The PCBs are present in different shapes and sizes and are customized by keeping different parameters in mind such as the scope, type, and working of the circuit. Usually, people have seen rectangular or square PCBs but one must know that round PCBs bring flexibility and functionality in the design and features of the circuits. To easily understand these, let's have a look at their introduction:
"Round PCBs are different from rectangular or square PCBs in terms of shape and applications and these bring factors like space utilization in circuits and provide better performance in different scenarios."
These PCBs introduce signal integrity in the high-frequency circuits because the components are tightly packed in the curved traces and as a result, better performance is gained. The difference is the presence of the curves in the round PCBs that have multiple advantages in the circuits.
Just like other PCBs, the manufacturing of the round PCBs involves different steps and special techniques are applied in these steps. Let’s have a look at these steps:
A PCB design software is used to get started with the design process of round PCBs. it creates the schematic and layout of the circuit. In the case of round PCBs, great care and attention are required because of the curves. The route tracing and component placement are different from the rectangular or square PCBs.
Once the round PCBs are designed, the process of Gerber file generation is carried out. This file has multiple instructions and information regarding the design and some of them are listed below:
The Garber file just discussed is used for the creation process of the photomasks. These are the essential photographic films that have patterns related to the different layers in the round PCBs. A large sheet of laminated material such as the FR4 is cut into the designed panel. A feature of this panel is, that it is pre-drilled with the registration hole so that it may be aligned with the design.
A photosensitive film (photoresist) is put to the copper foil in the laminate panel's inner layers.
The photomasks for these layers expose the required patterns to ultraviolet (UV) light. The exposed photoresist hardens, leaving the unexposed portions soft. The panel is then processed, eliminating any unexposed photoresist. This leaves the copper traces exposed. The visible copper is chemically etched away, leaving the inner layers with the appropriate circuit designs.
The design is now get ready with different processes such as the lamination of the surface and then drilling the holes according to the design. If the design consists of different panels then all of these are aligned together to get the best output. Once the panel is ready, the imaging and etching of the outer layer are carried out to create the final product in terms of design.
The PCBs are then passed through the process of platting. Here, a thin layer of the conducting material is applied to the required arrears to provide conductivity. Usually, this layer is copper because of its best-conducting characteristics.
Once the copper (or any other material) is traced on the round PCBs, a solder mask is applied to the PCB so that the traces may be protected against oxidation. In the end, the silkscreen is applied to the PCBs to add more details.
The applications of the round PCBs are the same as the traditional ones but they play a crucial role in improving factors such as performance and space constraints. Here are some advantages that you must know:
The consumer electrics are changing day by day. Smart technologies have made these electronics smaller and more stylish. The round PCBs help to get better performance in the smaller space. For instance, these are used in smartwatches, fitness trackers, and related wearables where the round shape fits into the device easily.
The medical devices are becoming smaller and smarter. For instance, the large X-ray machines, or blood pressure measuring devices are smaller now and are used as wearables. The round PCBs are used here because of their round curves and smart shape to fit in these devices.
The round PCBs are not only smart but are more appealing in their looks. The automotive industry requires circuits that not only provide better performance but also look more stylish. Some automotive instrument clusters and control panels always prefer round PCBs because of their look.
As a result, we have understood the round PCBs in detail in this article. We started with the introduction to the round PCBs and then saw how these PCBs are designed and ready to work. We saw why these are better in performance and in the end, we discussed how to get the best PCBs from PCBWay.com. I hope all the points are clear now and if you want to know more, you can contact us.
Hello seekers! I hope you all are doing great. Today, we are interested to learn about a basic and one of the most crucial topics in the field of electronics that is, the difference between active and passive components. Knowing the difference between these two is not only fruitful for beginners but also helps to understand the output and nature of electrical and electronic devices throughout the circuit design process.
While designing electrical or electronic circuits, it is crucial to get the best components. There are different features that affect the performance of these tiny components, including material, type, manufacturing techniques, etc. It's a good practice to get the components from a trusted source, and I suggest you buy them from PCBWay. This is one of the most trusted sources not only for buying the components, but it helps the customer from designing the PCB to prototyping as well. It is the one-stop for almost all the circuit manufacturing and assembly.
The buyer simply has to visit the website, where thousands of quality products, including active and passive components, are listed with all the details. The buyer can see and select the best match for the project. They can see the raw material, packaging, product number, description, and other details so that even a person with no technical knowledge can choose the best product. So, I recommend you visit PCBWay Fabrication House online, and you can order your components from anywhere.
These two categories are differentiated by different parameters, and we’ll discuss them in detail. We’ll start with a simple comparison between the active and passive components and after that, we’ll discuss each and every point in detail to gain a grip on the concept. We’ll study the introduction, features, and examples of these components and in the end, we’ll see where we can get the best components in the most convenient way. Let’s start with the difference:
A circuit is made of different types of components, and it is not completed unless all the necessary components are properly designed. It requires the components, the wires to create the connection between them, and the external source as well. Before designing any circuit, the most important step is to know the nature of its components. On a border scale, the electrical components are classified into two categories:
There are different ways to differentiate these two and we’ll discuss these in detail. The structure, features, material, and other basic features decide the category. At a higher level, the circuit is not complete until it uses both these types. The details of these components will be shared with you in just a bit but before this, have a look at this chart that summarizes the difference between these two types:
Feature |
Active Components |
Passive Components |
Power Source |
Require an external power source to work such as a battery, power supply, etc |
Do not require external power for their functioning the internal structure is enough for this |
Function |
|
|
Examples |
|
|

Can provide power gain, which means they amplify signals |
Cannot provide power gain, therefore attenuating or weakening signals in the circuit |

Can passively influence the flow of current and voltage |
Complexity |
These are generally more complex because they are made from semiconductors |
Generally simpler because these are made from basic materials |
Applications |
|
|
Examples of use in a circuit |
Transistors amplify a weak signal in a microphone; ICs process data in a computer |
Resistors control the brightness of LEDs, and capacitors smooth out the voltage from a battery |
The details of this table are explained here in the form of a basic introduction of active and passive components. I’ve tried to show the introduction in such a way that you can compare it easily.
The active components provide an active influence when electricity is applied to the circuit. These are the semiconductor materials that possess features like an amplification of the output, electrical current flow, electrical signal generation, etc. In simple words, active components work with the external power source and actively contribute to signal manipulation. The following are the fundamental features that help to understand the basics of active components:
As mentioned before, these components always require an external power or electricity source to start working. Therefore, these are the semiconductor components that are useless when there is no external power source.
Active components can amplify, switch, or manipulate the electrical signals of the circuits. These are also referred to as master conductors because they direct the current with great precision.
The superpower of the active components for which these are recognized is the amplification of the signals. A weak or low-frequency signal can be amplified with these components, and these can crank into a more audible or usable form.
Another feature that is associated with the active components is the lighting speed of these components to switch the electrical signals on and off. These are considered the digital traffic signals that control the electrical flow in the circuit.
These are usually semiconductors, and the scope of these components is not just limited to simple electronic circuits; complex circuits, such as solar cells, have the implementation of active components.
Some important examples of the active components will help us understand them thoroughly.
The passive components are entitled to be the workhorses of the electric circuit world. These are the fundamental components that are essentially required in circuits. These are different from the active component because they generate their energy to work. The following features of these components will help you understand why they are called "passive" components:
The main feature of a passive component is its ability to interact with the circuit using the present electrical signal or the energy of the circuit.
The passive components have different ways in which they can affect the flow of electrical current, voltage, or the frequency of the circuit. Some of these ways are:
Controlling the electrical flow
Filter the energy
Store the power and electricity
Distribute electrical energy in the circuit
These features result in the shaping of the electrical circuit's performance according to the requirements.
These components are present in different sizes and shapes, and they are the basic building blocks when complex circuits are designed. Collectively, these components can create the circuits that perform the variations in the tasks.
The most common example of a passive component is a resistor. These regulate the flow of electricity and are considered tiny dams in the circuit. There is a large variety of resistors therefore, these are usable in almost all types of circuits and are the most crucial part of these circuits.
The capacitors are also passive components of the circuit. These can store electrical energy in the form of electrical fields because of their internal structure. These are the tiny batteries that help in the voltage regulation of the circuits. The main use of capacitors is in circuits where the direct current (DC) of the current has to be blocked and the circuit only allows the alternative current (AC).
Inductors are the passive components that deal with the magnetic field around them. These act like mini electromagnets and oppose the change in the current. As a result, these smooth the electrical fluctuations and can be used to filter unwanted signals as well.
Hence, in this way, you know the difference between the active and passive components. These are the fundamental concepts of electrical circuits, and if these are clear, the user can design, learn, and understand the complex concept in no time. We started with a chart of the differences between these components and then explained each point in detail. We saw the definitions, features, and examples of both types in the end. Moreover, we also understood the best way to easily buy any type of electrical component from PCBWay. I hope I have discussed all the things in detail, but if you want to know more, you can ask in the comment section.
Hello, peep! I hope you are doing great. Today, I’ll explain to you a very basic and interesting topic in the electrical world. We know printed circuit boards act as the backbone of complex circuits, and microwave PCBs are an important member of this family. These are the integral components of the high-frequency circuit designs. We will study microwave PCBs in detail and find out the perfect type of circuit where these are widely used.
Now, the question arises as to where the best PCBs can easily be ordered. It is crucial to get sensitive devices like printed circuit boards from the right vendor because quality is the first parameter to be considered in such shopping. One of the most reliable sources to get microwave PCBs without any difficulty is PCBWay Fabrication House. It is a popular manufacturer and seller of PCBs and their prototyping. The users can have low-volume production and a wide variety of PCB assembly services, all of which are available under one roof.
PCBWay is one of the largest manufacturers of PCBs and provides a great variety of PCBs and related components. They not only sell PCBs but also provide services such as manufacturing, designing, prototyping, and other processes. They have a large staff that helps the users to get their queries solved instantly. I suggest you visit PCBWay.com to get any services related to electronic circuit components, especially PCBs.
In this article, we’ll start learning the introduction to microwave PCBs through the basic definition. After that, we’ll understand the features in detail and see the basic applications in different sensitive domains of electronics to understand their scope. Here is the introduction of these PCBs.
Microwave printed circuit boards are a specialized category of PCBs that are designed to be operated according to the stringent requirements of high-frequency circuits. As the name suggests, the basic purpose of using these PCBs is to have the best performance at a higher level of frequency, even in microwaves where other PCBs do not provide the right performance. At such high frequencies, these PCBs show the best performance with minimal loss and distortion. This is the reason why these have applications in extraordinary fields such as aerospace, medical devices, etc.
The basic reason behind the best performance of this PCB is because of its design. From material selection to the fabrication process, these PCBs are designed to keep high frequency in mind. Hence, the nuances of the material are vital to achieving signal integrity with reliable output.
Microwave PCBs are different from traditional PCBs because they are designed for the extraordinary Understanding the features of microwave PCBs will help you a lot to know their basics and applications.
As mentioned before, the basic reason behind the robust performance of these PCBs is because of the material used in their production. These are made with specialized substrate materials that have low dielectric constants and low dissipation factors. Common materials used in their production are:
Polytetrafluoroethylene (PTFE)
FR-4 with PTFE
Ceramic-filled PTFE composites
Here, the basic material is PTFE, whereas FR- and ceramic-filed PTFE are its variants.
As compared to ordinary PCBs, microwave PCBs are employed with thicker copper layers. This not only reduces conductor loss but also contributes to better thermal management. For this, more material is required, and usually, the thickness of microwave PCBs is greater than that of many other types.
One of the most critical features of microwave PCBs is their impedance maintenance. They are designed in such a way that they prevent the phenomenon of signal reflection in microwave signals. Microstrip or stripline configurations are important techniques used during its design, and this ensures efficient power transfer from one point to another in the PCB.
An important feature of this PC is that, during the design process, great care is taken to isolate the component. This includes processes such as strategic component placement and optimized routing so that the circuit has minimal crosstalk.
Another reason why these PCBs provide the best signal integrity is the via design. The following table shows the via design options in the microwave PCBs:
Feature |
Through-hole Via |
Blind Via |
Buried Via |
Connection |
Extends through the entire PCB |
Connects an outer layer to one or more inner layers |
Connects inner layers without penetrating the outer layers |
Visibility |
Visible on both the top and bottom of the PCB |
Visible on one side of the PCB (typically the top) |
Not visible on either side of the PCB |
Manufacturing method |
Drilling through the entire PCB |
Drilling partway through the PCB, then plating the remaining portion |
Laser drilling or plating through micro vias |
Cost |
Less expensive |
More expensive than through-hole vias, less expensive than buried vias |
Most expensive |
Reliability |
Highly reliable |
Less reliable than through-hole vias, more reliable than buried vias |
Least reliable |
Applications |
High-current applications, high-density designs |
Applications where vias need to be hidden on one side of the PCB, such as for cosmetic reasons or to prevent EMI |
High-density designs, applications where vias need to be hidden on both sides of the PCB |
Another way to maintain the performance of these PCBs is to set the electromagnetic interference (EMI) and electromagnetic compatibility (EMC) compliance in the design. This helps a circuit to adhere to the regulation of electromagnetic standards so that every component in the circuit has the experience of the right EMI and EMC. This not only results in better circuit design but is useful in testing and validation.
As we have discussed so far in this article, microwave PCBs are a specialized type of PCB. these have applications in the areas where PCB tolerance and high sensitivity are required. Here are some major fields where these PCBs are used:
In areas like aerospace and defence, high-performance circuits are extensively used and reliability is an important factor of these circuits. Here, the microwave PCBs are considered one of the best choices. The two most critical applications are discussed below:
For military and aerospace applications, radar systems are the basic devices and these require accurate performance all the time. In these devices, microwave PCBs help to get precise and rapid signal processing.
The electronic warfare system circuity requires a base that may bear the high frequency easily. For such systems, the microwave PCBs are the best choice. As a result, these PCBs help to have the best performance.
The microwave PCBs are the integral base of the systems in the telecommunication fields. These systems are loaded with wireless communication devices and here, usually, the best frequency is in the form of microwaves. Therefore, most of the devices use microwave PCBs to get the best performance.
Communication with the satellite requires a high frequency to communicate through the distance. For this, reliable devices that can bear the high frequency without disturbing the output are required and this is possible with the microwave PCBs.
The sensitive areas like medical imaging devices where accuracy and precision are the life-saving parameters, are always the best pieces of equipment used and microspace PCBs are worth discussing as part of these devices. Here are some medical applications where these PCBs are used:
In medical imaging devices, accuracy is an important factor because of the limitations of the colours. Here, the base of these devices is the microwave PCBs, because ideally, these do not distort the output even at the high frequency. Two important applications in this regard are magnetic resonance imaging (MRI) and computed tomography (CT) scanners.
These PCBs have applications in radio frequency (RF) ablation systems, where they help the expert work on medical treatment with precise control.
In laboratories and scientific research departments where heavy calculations are required and the device runs continuously for a long time, it is better to use microwave PCBs because of their feature to bear high frequencies.
The research applications get the most benefit from these PCBs and can work with the best results from their long-term calculations.
The scope of microwave PCBs is not limited to these fields but is widely used in industrial automation, consumer electronics, etc.
So, in this article, we have understood the basics of microwave PCBs. We started with the basic introduction and understood the features to clarify the concepts. After that, we saw the applications of microwave PCBs in different sensitive areas where they are used because of their features like accuracy and precision. Moreover, in the beginning, we discussed how PCBWay is the best choice to buy microwave PCBs.

Printed circuit boards are the most important and basic component of the electronic industry. These boards have made it possible to create and run circuits on every level and have served as the backbone of any electronic device. With the growing demand for technology, PCBs have gone through multiple evolutions. The transformation of PCBs has made it possible to create innovative and better electronic circuits.
Today, we are talking about the emerging trends in PCB that are reshaping electronic circuits and the components used in innovative designs. But before this, it is important to understand the importance of using the emerging trends for the circuits.
PCBs are versatile components, and not all PCBs are ideal for a particular type of circuit. However, it is always advisable to use the most trending technologies to meet the needs of the time, especially in the case of designing Multilayer PCB. Here are some important and obvious advantages to using the trending technologies:
The enhanced technologies are made to provide better functionality and performance. The researchers are working on providing the best techniques to make the lower PCBs work more efficiently, even on low power. Experiments are being performed on different materials to improve electricity flow and resistance to heat.
Similarly, multiple techniques are introduced to reduce the size of components and boards to provide better accommodation for components in the boards. As a result, more components can be settled on the same board, and better performance is expected.
The advanced technology is more reliable because of the multiple experiments and research performed on PCBs. The advanced PCBs have a lower risk of failure and other related factors, and they have a longer life as compared to the older technology PCBs. For instance, in the latest PCBs, lead-free solder and other safe materials are used to ensure reliable working for a long time. Moreover, conformal coating is used as a coating to provide protection to the PCB against moisture, dust, and other contaminants that can harm the PCBs.
The advanced technology provides more versatility and variety in operations related to PCB functionalities.

Hi, I hope you all are doing great. Today we are talking about the silkscreen on the printed circuit boards (PCBs). We know that PCBs are the essential parts of electronic devices, and there are a variety of PCBs for different circuits. Generally, silkscreening is the process of surface printing with the help of a design cut out on a sheet. But, we are particularly talking about the silkscreen on the PCB.
It is a crucial step in the PCB design and plays a role during the PCB assembly to make sure the PCB is designed well. Generally, silkscreen is used to provide basic information about the components on the PCBs. This article has a silkscreen introduction, types, and methods.
The PCB Silkscreen is a layer of non-electric permanent epoxy ink present in the form of text or different graphics on the surface of PCBs. The basic use of silkscreen is to provide information, which may be the names, types, and polarity of the components. Moreover, it also includes information about the manufacturing company, such as its name or logo.
Silkscreen is also known as labelling or serigraphy and is the main technique in different industries. It is highly useful during the process of fabrication to verify the component's placement. Therefore, the PCB silkscreen helps the assembler, identify the perfect place for the components.
Multiple PCB companies offer services for prototype and assembly, and one of the most suitable names among them is PCBWay. It is a China-based company that is known for its quick services with no quality compromise. They provide the most reliable boards, and their critical testing system is responsible for the best results and top-quality PCBs.
Another advantage of choosing PCBWay Fabrication House is the competitive prices because they directly take orders and there is no need for any broker to buy the PCBs. The quick turnaround time, wide range of products, high-quality latest machines, and online status of the orders are the most significant features of PCBWay.
The PCB silkscreen varies depending on the design and type of the PCB, but there are some basic components of silkscreen that must be included in all silkscreens. Here are some of these:
The silkscreen is a crucial tool for the perfect assembly of the PCBs. It makes sure that all the components are placed accurately and that the PCB is functioning well. There are multiple reasons to use the silkscreen, and the most important among these are given next:
The component side of the PCB is the one where all the components of the PCB are to be mounted. The silkscreen is important to indicate the right place of the components, such as the resistors, inductors, capacitors, etc. The user simply has to follow the design on the silkscreen, and the PCB is ready to use.
Many components of the circuit are polarized, such as the diode, capacitors (polarized), integrated circuits, etc. For such places in the PCB, the silkscreen has different indications, such as dots or other symbols, to identify the right direction. This facilitates the user a lot, and it is also vital for the PCB's health when the electricity passes through the circuit because the component set at the wrong polarity may damage the PCB.
Silkscreen also provides information about the manufacturers, so the users do not have any difficulty dealing with the PCBs. This is because every manufacturer has a specific set of working rules. This information may include the following points:
This helps the users at different levels, whether they are manufacturing, placing, or using the PCB.
The silkscreen makes the PCB more attractive. These are printed in a contrasting colour to the PCB surface. In this way, the PCB looks more neat and pleasing. The better the quality of the silkscreen, the better it looks. For this, more appealing colours of the silkscreen are used to enhance the texture and design.
One must know that the PCBWay offers multiple colours of ink for customers, including yellow, green, white, and black. In this way, the customers can choose the specification of PCB silkscreen of their own choice. PCBWay also provides a variety of fonts and designs; therefore, all the controls in the customer’s hand and the proper guidance of PCBWay at each step help to make your creativity live.
There are several ways of producing silkscreen and the manufacturers select the most accurate by keeping some parameters in mind. Some of such parameters are the material of the PCB, cost, creation, and manufacturer of the silkscreen. Some of the most important methods that you must know are given here:
This technique is known for its high-resolution results, and it does not require a printing plate because it uses liquid plates. An advantage of using it is its ability to avoid shorts and maintain the PCB’s electrical integrity. This method uses liquid curable inks that are cured with UV lights. A design is applied to the lights so that only the required area is hardened, and then the unwanted part is removed. This design is now used for the silkscreening process on PCBs.
When the laser is applied to the protective layer of the PCB, the copper underneath is exposed and as a result, the PCB is ready for more processes.
This is the most traditional method for PCB silkscreen and is also known as Hand screen printing for PCB. In this process, the stencil is created on the mesh. The ink is applied to the mesh, and a squeegee is used to force the ink onto the surface of the PCB. The mesh or stencil has a specific design according to the requirements, and as a result, the silkscreen is printed on the surface.
The principle of this type of printing is the same as that of the inkjet printer. The high-speed inkjet printer is used to print the board directly. The acrylic ink is applied directly to the CAD data. This ink is then cured with UV lights during the printing process. Usually, DLP is applied to the PCB after the application of the solder mask. This is a quick method that involves fewer steps, but the users get high efficiency and precision. Moreover, factors such as setting the font size and style are under the control of the designers.

Printed circuit board is a very important part of electronic devices. You will find them in all electronic appliances. To make a good quality PCB, it is very important to select high-grade materials. A PCB mainly consists of a NON-conductive material. Conductive lines are etched or printed on them.
PCB materials are mainly of 3 types.
Among these 3, FR-4 is the most common. This article will discuss all that you need to know about FR4 PCB Fabrication. We will discuss all about FR4. We will focus on its advantages.
Here are some samples of FR4 PCBs made by PCBway.
Here are some common FR4 PCB assembly mounting technology types:
SMT is the most widely used technology for mounting components on FR4 PCBs. In SMT, components are mounted directly onto the surface of the PCB using solder paste. The solder paste is applied to the solder pads on the PCB. Then the components are then placed on top of the solder paste. The PCB is then heated. It melts the solder. Thus it creates a permanent electrical and mechanical connection between the component leads and the PCB.
THT involves inserting component leads through holes drilled in the FR4 PCB. The leads are then soldered on the opposite side of the PCB to create a connection. THT is commonly used for components that need additional mechanical strength. THT is also used for high power or high voltage requirements.It is less commonly used than SMT. Still it is relevant for certain applications.
Many PCB assemblies combine both SMT and THT components. This is called mixed technology assembly. In such cases, the SMT components are typically mounted first. After that, the THT components are inserted and soldered on the opposite side of the PCB.
COB technology involves mounting bare semiconductor chips directly onto the FR4 PCB. This technology works without traditional packaged components. The chips are typically attached using conductive adhesives or wire bonding techniques. COB technology is commonly used for high-density applications where size and weight reduction are critical, such as in mobile devices.
BGA is a surface mount technology that utilizes an array of solder balls on the underside of the component. These solder balls create electrical connections between the component and the PCB. BGA components offer high pin counts and are commonly used in applications that require high-performance processors, graphics chips, or other integrated circuits.
Micro BGA is a variation of BGA technology that utilizes smaller solder balls and tighter ball pitches. This technology is often used for miniaturized electronic devices where space is limited.
These are some of the common FR4 PCB assembly mounting technology types. The selection of the appropriate technology depends on the specific requirements of the PCB design, the complexity of the circuit, the size of the components, and the intended application. Manufacturers consider these factors to ensure a reliable and efficient assembly process.
FR4 PCB fabrication typically involves the following steps:
First, we need to create the PCB layout. We have to use design software like Proteus, Kicad, Eagle etc. Then we need to place components. Then we need to route the traces. At the time of routing, we should avoid DRC errors. It is very important to define the board dimensions.
Following is a typical PCB layout:
The next step is Gerber File Generation. We can Gerber files from the PCB design software. These files have the necessary information about the PCB layers, copper traces, solder masks, and other design elements.
You can generate Gerber files using Atrium, Kicad etc.
A typical gerber will look like the following picture:
Choose the appropriate FR4 material for the PCB based on the desired electrical and mechanical properties.
Choosing the appropriate FR4 material for a PCB involves considering the desired electrical and mechanical properties. Here are some key factors to consider:
HASL (Hot Air Solder Leveling):
HASL is a widely used surface finish for FR4 PCBs. In this process, the exposed copper pads on the PCB are coated with a layer of tin-lead solder. The PCB is then passed through a hot air leveling machine. The machine blows hot air to level and distributes the solder evenly across the surface. This ensures a flat, solderable surface for component attachment. HASL offers good solderability and robustness. It is relatively cost-effective. However, it may not be suitable for fine-pitch components due to the relatively thick solder layer.
ENIG (Electroless Nickel Immersion Gold): ENIG is a popular surface finish for FR4 PCBs.If it suitable for applications requiring good electrical performance and solderability. In the ENIG process, the exposed copper pads are first coated with a thin layer of electroless nickel. Nickel provides a diffusion barrier between the copper and the final layer. Next, a thin layer of immersion gold is deposited on top of the nickel layer. The gold layer protects the nickel from oxidation. It provides excellent solderability. ENIG offers a flat surface, good corrosion resistance, and is suitable for fine-pitch components.
OSP (Organic Solderability Preservative):
OSP is another surface finish option for FR4 PCBs. It is suitable for applications where cost and environmental concerns are important. OSP is a thin, organic coating. It is applied directly to the exposed copper pads. It provides a temporary solderable surface that protects the copper during storage and transportation. When soldering, the OSP layer is removed during the soldering process.
Supplier and Industry Standards: Consider the reputation and reliability of the FR4 material supplier. Additionally, check if the chosen FR4 material complies with industry standards, such as IPC-4101 or UL-94.
When choosing FR4 materials for PCB manufacturing, there are various supplier and industry standards that can help guide the selection process. Here are some key standards to consider:
Supplier Standards:
Industry Standards:
We have to Consider these supplier and industry standards when selecting FR4 materials. This makes sure that the chosen materials meet recognized quality, safety, and performance criteria. It is essential to collaborate closely with reputable suppliers and consult relevant standards to make informed decisions regarding FR4 material selection.
Arrange multiple PCB designs on a larger panel. It is for efficient fabrication and cost optimization. This step involves duplicating the design layout. It also adds break-off tabs for later separation.
Dirt, oils, or oxidation may affect the bonding between the copper and the substrate. Clean the copper-clad FR4 material to remove these.
The following figures show different types of cleaning techniques:
Print the Gerber files onto a photosensitive film. This process uses a machine that exposes the film to UV light through a photo tool or a film negative. The following figure shows gerber file imaging.
Place the photosensitive film onto the cleaned FR4 material. Pass it through a laminator. The heat and pressure bond the photoresist film to the copper layer. Following are some images of FR4 laminates.
Expose the laminated material to UV light. You have to use the photo tool or film negative as a mask. The UV light cures the photoresist. UV light also hardens it in the areas not covered by the opaque parts of the mask.
Remove the uncured photoresist using a developing solution. This reveals the underlying copper layer. Thus it creates the required circuit pattern.
Submerge the panel in an etching solution. It’s typically a chemical mixture that removes the exposed copper. The etching process selectively removes copper. It leaves behind the circuit traces defined by the cured photoresist.
Remove the remaining photoresist from the panel.Use a stripping solution or plasma treatment. This exposes the copper traces for further processing.
Drill holes into the panel at the designated positions. These are for component mounting and interconnection. These holes allow for the insertion of through-hole components or the formation of vias for multilayer PCBs.
Plate the drilled holes with a conductive material, such as copper. Plating establishes electrical connections between different layers of the PCB.
Apply a solder mask layer over the surface of the PCB. Leave openings only at the solder pad locations. The solder mask protects the copper traces. It also prevents solder bridges during assembly.
Use a silk screening process to print component identifiers, logos, and other markings onto the PCB surface. This step helps with component placement and identification.
Apply a surface finish to protect the exposed copper and facilitate soldering. Common surface finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservative), and immersion tin or silver.
Perform electrical tests. The tests check the functionality and integrity of the fabricated PCB. This can include tests such as continuity testing, insulation resistance testing, and high-voltage testing.
Cut or route the panelized PCB into individual boards along the break-off tabs created during the panelization step.
Inspect the finished PCBs for any visual defects. There may be solder mask misalignment, open or shorted traces, or incorrect component markings. Correct these errors.
Package the PCBs appropriately. Prepare them for shipping to the intended recipients or assembly facilities.

A PCB prototype is a functional sample of a printed circuit board that serves as a proof-of-concept for a specific design. It allows engineers and designers to validate their circuit design, test its functionality, and identify potential improvements or issues before proceeding with mass production. PCB prototypes typically undergo rigorous testing and analysis to ensure their reliability, performance, and manufacturability. Prototyping is an essential step in the product development cycle as it helps to refine the design, reduce costs, and minimize risks associated with full-scale production.
PCB prototyping offers numerous benefits and advantages throughout the product development cycle. It enables designers to visualize their circuit design, validate its functionality, and identify and rectify any design flaws or issues. By identifying and addressing these problems early on, costly mistakes can be avoided during mass production. Moreover, PCB prototyping allows for performance optimization, improved product quality, and reduced time to market.
Prototyping also provides an opportunity to evaluate different design alternatives and assess their feasibility and effectiveness. It helps designers gain a deeper understanding of the interaction between components, identify potential bottlenecks, and optimize the layout for better signal integrity, thermal management, and manufacturability.
The design process is a crucial aspect of PCB prototyping, encompassing schematic capture and PCB layout design.
Schematic capture involves creating a graphical representation of the circuit design using specialized software tools. It involves selecting and connecting various electronic components to form a functional circuit diagram, capturing the electrical connections and relationships between components. During this stage, designers must consider factors such as the desired functionality, component availability, and compatibility.
The following image is an example of a schematic capture.
Once the schematic is finalized, the next step is to create the PCB layout design. This involves translating the circuit diagram into a physical representation of the PCB, positioning components, and routing traces to establish electrical connections. PCB layout design requires careful consideration of component placement. Designers should consider signal integrity, power distribution, and manufacturability too. Designers need to optimize the layout to minimize noise, ensure proper thermal dissipation, and facilitate ease of assembly.
Following is an example of a PCB layout:
To design PCB prototypes effectively, it is essential to choose the right tools and software. Numerous software packages are available that facilitate schematic capture, PCB layout design, and simulation. These tools offer features such as component libraries, design rule checks, and simulation capabilities, enabling designers to create accurate and optimized PCB prototypes.
When selecting tools, it is important to consider factors such as the complexity of the design, ease of use, availability of support, and compatibility with manufacturing processes. Popular software tools for PCB design include Altium Designer, Eagle, KiCad, and OrCAD, among others. Additionally, designers should also consider the availability of design resources, community support, and compatibility with the chosen PCB manufacturing service.
To ensure the success of a PCB prototype, adherence to certain design guidelines is crucial. Consider the following aspects during the design process:
Efficient component placement and routing contribute to optimal signal flow, reduced noise interference, and ease of assembly. Consider factors such as signal paths, thermal management, and component accessibility while placing and routing components on the PCB. Group components logically based on their functions and connections, and minimize the length and complexity of traces to avoid signal degradation and interference.
The following image shows a good arrangement of components.
Proper allocation of power and ground planes helps ensure a stable power supply. It reduces noise and improves signal integrity. Implementing a multilayer PCB design with dedicated power and ground planes is often beneficial for high-speed and complex designs. Ensure that power and ground traces are sufficiently wide to minimize resistance and voltage drops, and employ vias to establish connections between different layers.
The image below shows the power and ground planes.
For designs involving high-speed signals, careful attention must be paid to signal integrity. Consider factors such as impedance control, termination techniques, and signal routing to minimize reflections, crosstalk, and other signal integrity issues. Use controlled impedance traces for high-frequency signals, and employ techniques such as differential signaling and shielding to minimize electromagnetic interference (EMI).
The following picture shows Crosstalk Checking in PCB Layout for Signal Integrity Validation.
Once the PCB design is complete, the next step is manufacturing the prototypes. The manufacturing process typically involves two main stages: fabrication and assembly.
The fabrication process involves translating the PCB design into physical reality. It includes steps such as creating the PCB stack-up, applying the copper layers, etching, drilling, and applying surface finishes. Advanced fabrication techniques, such as advanced routing and via technologies, are employed to meet the design requirements. During the fabrication process, designers must consider factors such as the choice of substrate material, layer stack-up, copper weight, and surface finish to ensure the desired performance and reliability of the PCB prototype.
The following image shows the sequence of PCB fabrication:
During the assembly process, electronic components are mounted onto the fabricated PCB. This can be done through manual or automated processes, depending on the complexity and scale of the design. Once the components are placed, they are soldered onto the PCB, and any necessary inspections and tests are conducted. Designers must ensure proper component selection, compatibility with the manufacturing process, and appropriate soldering techniques to achieve reliable and robust connections.
PCBWay has PCB assembly capabilities.
The following picture shows the mixed 2-layer board assembly:
After the assembly process, the PCB prototypes undergo rigorous testing and validation to ensure their functionality and performance. Various tests, such as functional testing, electrical testing, and environmental testing, are conducted to verify the design's reliability and adherence to specifications. Testing may include checking for short circuits, open circuits, component functionality, and signal integrity. Designers must work closely with the manufacturing partner to define the testing requirements and ensure that the prototypes meet the desired quality standards.
PCBway’s testing and validation process is excellent. All of a PCB's design specifications are examined by the DFM inspection. This check specifically searches for any features that might be troublesome, redundant, or missing altogether. Any one of these problems could have a significant negative impact on how well the project works in the end. For example, too less space between PCB components is a typical PCB design problem. This may cause Short circuit and other issues.
DFM checks help save production costs and unanticipated expenses by spotting potential issues before manufacturing even starts. This is because fewer boards were scrapped as a result of these tests. This process can offer high-quality products at reasonable prices.
The following image shows the process of the DFM check.

Furthermore, Gerber files incorporate not only the geometric layout of the PCB but also important manufacturing details. This includes parameters like trace widths, pad sizes, drill hole dimensions, and material specifications, ensuring that the manufacturing equipment performs the necessary operations accurately and consistently.
In summary, a Gerber file is a standardized file format that encapsulates the critical information required to produce a PCB. It serves as a vital communication medium between the PCB design software and the manufacturing equipment. By conveying precise instructions and specifications, Gerber files enable manufacturers to bring PCB designs to life with the utmost accuracy and fidelity.
By analyzing the Gerber files, manufacturers can identify potential manufacturing issues, such as inadequate spacing between components, unachievable trace widths, or insufficient clearances. This helps in optimizing the design for efficient and cost-effective manufacturing. Addressing DFM concerns at the early stages of the design process saves time, reduces manufacturing risks, and streamlines the production timeline.
Detecting errors early in the manufacturing process saves time and resources. Inspecting Gerber files helps identify errors such as missing or overlapping features, incorrect layer assignments, or mismatches in the solder mask and silk screen layers. With the assistance of an advanced online viewer like JLCPCB's, design engineers can quickly spot these errors and rectify them before initiating the manufacturing process, minimizing rework and production delays.
Gerber files act as a common language between designers, manufacturers, and assemblers. Inspecting the files ensures clear communication and effective collaboration, reducing misunderstandings and streamlining the entire production cycle. With the availability of the Online Gerber Viewer, stakeholders can easily share and discuss design iterations, enabling smoother collaboration and efficient decision-making.
