A Detailed Guide on PCB Manufacturing Process

Hi Friends! I welcome you on board. Happy to see you around. In this post today, I’ll document a detailed guide on the PCB manufacturing process.

PCB is hands down a crucial part of modern electronics. From cell phones and digital clocks to remote control and television sets, you will find inside a printed circuit board that connects the electrical components through sophisticated layers of copper traces. These electrical copper traces help in the flow of current through the connected components.

Needless to say, PCB has revolutionized the electronics industry. You’ll never find bulky electronics incorporated with scores of wires and electrical components. Nowadays, electronic devices are more compact and sophisticated, cover less space, and are capable of doing more functions than their predecessors.

• If you don’t want to dive into the nuts and bolts of this hectic PCB manufacturing process, you can outsource your PCB design. There are many online PCB Companies i.e. NextPCB, PCBWay, etc. that help you design your PCB according to your projects' needs & requirements.

• You can simply submit your details, and they will create the PCB design customized to your exact requirements.

A Detailed Guide on PCB Manufacturing Process

Circuit boards are mainly categorized into three main types. And all these types are used in different applications.

You need to understand the main difference between all these types, so you can pick the right one based on your requirement.

Main Types of Printed Circuit Board

The following are the three main types of circuit boards.

Single-sided Circuit Boards

Single-sided PCB, also known as single layer PCB, is made with the rigid laminate of woven glass epoxy material which carries one layer of copper traces on one side of the board and another side is used to place the different component on the board. These electrical components are electrically connected through copper traces on the board.

Double-sided Circuit Boards

Double-sided PCB, also known as two-layer PCB, is composed of the same rigid laminate of woven glass epoxy material as single-sided PCB, but here in this case both sides of the board are covered with copper traces. And mainly based on the applications, these traces are made with varying thicknesses.

Multiple-sided Circuit Boards

Multiple-sided PCBs are similar to single-sided or double-sided boards, but here in this case copper foil is used instead of copper coating. The copper foil continues to make multiple layers until you get the desired number of layers.

Main Parts of PCB

Before we study the complete manufacturing process, let’s discuss the main parts of the printed circuit board.

Substrate

This is the skeleton of PCB – the most basic structure. Fiberglass is used to make the substrate. Fiberglass extends the core strength to the PCB and keeps the board from breakage.

Copper Layer

The next part is the copper layer. Based on the type of PCB, copper foil or copper coating is used on one side or both sides of PCB. The purpose of this copper trace is to provide an electrical signal between the connected components on the board.

This is similar to the brain nervous system where neurotransmitters are connected with the muscles to collect and provide information to the brain.

Solder Mask

The third part is the solder mask. It is a protective layer made of a polymer that acts as a PCB skin. It protects the copper layer and keeps it from short-circuiting.

Silkscreen

Silkscreen, also known as legend or nomenclature, is the final part of the PCB. It is normally laminated on the components side of the board. This layer is used to represent symbol switch settings, logos, part number, test points, and component reference.

PCB Manufacturing Process

Hope you understand the main parts of the PCB. Now, let’s dig deep into the manufacturing process.

Step 1: The Design

It all starts with the basic design. A detailed PCB design is made on the dedicated PCB design software or you can also use online PCB design services to design your PCB.

Commonly used PCB design software is Eagle, Altium Designer, Pads, OrCad, KiCad, or Proteus, etc

Once the design is finalized, the file is exported. Make sure… you export file in the format that the manufacturers support. The commonly used file format is known as extended Gerber. Know that… different software include different Gerber file generation steps, however, they all include detailed information about drill drawing, copper tracking layers, component notations apertures, and other options.

Step 2: The Print

The plotted printer is used to print PCB. It generates the resultant film which is composed of various layers. The blank ink represents the conductive copper traces while the clear ink indicates the non-conductive areas. This is the representation of the inner layers. In outer layers, this trend is reversed i.e. the clear ink indicates the conductive copper traces and black ink indicates the non-conductive areas.

Step 3: The Substrate

The substrate is the skeleton of the PCB that is composed of fiberglass. This is an insulating material that connects the various elements.

Step 4: The layers

In this step, a laminate is created using the blueprints. This laminate is then covered with the photo-sensitive film which is also called a resist. This resist is composed of photo-reactive chemicals which when exposed to UV light, hardens the resist.

Step 5: Hardening the Photoresist Layer

The next step involves the revealing of underlying copper pathways. This is done by hardening the photoresist layer.

When a combination of laminate and resist is sent to the room under UV light, it hardens the photoresist layer.

Step 6: Removing Unwanted Copper

This step involves the removal of unwanted copper. An alkaline solution is employed to get rid of unwanted copper. Make sure during this process, it doesn’t harm the photoresist layer.

Step 7: Inspection

In this step, layer alignment and optical inspection are carried out. The inner and outer layers are aligned by the holes. A punch machine is used to make sure everything is aligned and in place.

Step 8: Lamination Process

At step 8, inner and outer layers are pushed together for the lamination. These layers are fused together once they are inspected, making sure they are defect-free.

Epoxy resin known as Prepreg is used with the metal clamps to keep these layers in place. The layer of substrate and copper coil is placed over the Prepreg. A mechanical press is then used to punch everything together where specialized pins are used to keep each layer in place. The PCB layers are fused together in the presence of epoxy that melts down due to applied heat and pressure. The top press plate and pins are then removed to pull out the actual PCB.

Step 9: Drilling

After the lamination, there comes the drilling process. But before initiating the drilling process, drill spots are located using an X-ray machine.

A computer-guided drill is used to create holes. After the drilling process, additional leftover copper at the edges is removed.

Step 10: PCB Plating

Once the drilling step has been completed, a certain chemical is used to fuse all layers together. This process is known as PCB Plating.

The PCB layers are then thoroughly cleansed together in a series of chemicals. This bathing process applies the copper layer on the top of the layer and in between the drilled holes.

Step 11: Outer Layer Imaging

After PCB Plating has been completed, another layer of photoresist is applied to the outer layers of the design. Which gets harden in the presence of UV light.

After coating the outer layers with photoresist, they are again fused together in the presence of certain chemicals like we did for inner layers in the previous PCB plating step. Though the plating process is the same as the previous step, the outer layers develop the plating of tin, thus guarding the copper of the outside layer.

Step 12: The Last Etching

The tin guard developed in the last out layer imaging is used to protect the copper layer during the etching of the outside layer. The same copper solvent is used to remove the unwanted copper while the tin guard continues to protect the copper of the outside layer.

Step 13: Applying the Solder Mask

The proper PCB connections have been developed once the unwanted copper is removed. Now comes the solder masking. The final panels are cleaned before applying the solder mask. Once the cleansing is done, solder mask film is applied with ink epoxy.

The final product is then exposed to UV light to remove the unwanted solder mask. After the removal of the unwanted solder mask, the PCB is heated in the oven that cures the solder mask and results in the green color of the PCB panels.

Step 14: Final Surface Finish

The final surface finish is achieved by the plating of materials like silver and gold. This surface finish results in developing the core strength and improves the bonding of the elements.

Once the plating with gold and silver is achieved, the resulting product is then silkscreened. The necessary information including company ID numbers, manufacturer marks, and warning labels have been printed on the PCB during this silk screening process.

Step 15: Electrical Testing

Once the final surface finish has been completed, the entire PCB goes through a series of electrical tests to ensure functionality.

These electrical tests include isolation and circuit continuity tests. The isolation tests scan the isolation values of PCB to ensure if there is any short circuit. While the circuit continuity test confirms if there are any disconnections in any area of the board. These tests not only confirm the board’s functionality but also how the initial PCB design is observed during this manufacturing process.

Moreover, these tests can be applied both ways: in the automated environment or under the supervision of a practiced technician.

• If you don’t want to dive into the nuts and bolts of this hectic PCB manufacturing process, you can outsource your PCB design. PCBWay Fabrication House helps you design your PCB for the required project.

• You can simply submit your details, and they will create the PCB design customized to your exact requirements.

Step 16: Final Cutting Step

Once the final product is run through a series of electrical tests, there comes a cutting process that results in removing and cutting the PCB from the original panel. You can cut PCBs from the original panel using V-groove or CNC machine.

Your final PCB product design is now ready that you can use in your electrical project.

D13003K Datasheet, Pinout, Power Ratings & Applications

Hi Friends! I welcome you on board. Thank you for clicking this read. In this post today, I’ll document the Introduction to D13003K. The D13003K is an NPN silicon transistor mainly employed for switching and amplification purposes. It comes with a power dissipation of around 50W which demonstrates the amount of energy this device releases during the functioning of this device. As this is an NPN transistor as here electrons are the major charge carriers. The collector current is 1.8A which means it can support load under 1.8A. The emitter-base voltage is 9V which means it needs 9V to bias this device and start the transistor action. I suggest you read this post all the way through as I’ll walk you through the complete Introduction to D13003K covering pinout, datasheet, power ratings, working principle, applications, and physical dimensions. Let’s get started.

Introduction to D13003K

• The D13003K is a power transistor made of silicon material and falls under the category of NPN transistors.
• This device is composed of three layers where one is a p-doped layer that stands between the two n-doped layers.

• This component comes with three terminals known as collector, emitter, and base. All these terminals are different in terms of doping concentrations.
• The power dissipation of this device is 80W which is the amount of power released during the working of this device.

• The D13003K belongs to bipolar junction transistors where electrons are the major carriers. The bipolar junction transistors are divided into two main types NPN transistors and PNP transistors. In NPN transistors electrons are the major carriers while in the case of PNP transistors holes are the major carriers. They are called bipolar junction transistors because both electrons and holes are responsible for the conductivity inside the transistor.
• These bipolar junction transistors are current-controlled devices because a small current at the base terminal is employed to control large output current at the remaining terminals.
• The MOSFETs, on the other hand, are voltage-controlled devices that come with terminals named drain, source, and gate.
• The mobility of electrons is better than the mobility of holes the reason NPN transistors are preferred over PNP transistors for a range of applications.

D13003K Datasheet

Before you embed this device into your electrical project, it is better to scan through the datasheet of D13003K. The datasheet features the main characteristics of the device. Click the link below to download the datasheet of D13003K:

D13003K Pinout

The following figure represents the pinout diagram of D13003K. This NPN transistor contains three terminals known as: 1: Base 2: Collector 3: Emitter All these terminals come with different doping concentrations. The collector terminal is lightly doped while the doping concentration of the emitter terminal is high. The base side is 10-times more doped than the collector side.

D13003K Working Principle

• The base pin plays a vital role to start the transistor action. When voltage is applied at the base pin, it will bias the device, and as a result, the current will start flowing from the collector to the emitter terminal.
• As this is an NPN transistor here current flows from collector to emitter terminal and in the case of PNP transistor current flows from emitter to collector terminal.

• These bipolar junction devices are not symmetrical in nature. And the different doping concentration of all three terminals is responsible for the lack of symmetry of this device.

• This means if we try to exchange emitter and collector terminals then the device will start working in reverse active mode, and stop working in forward active mode.

D13003K Power Ratings

The following table features the absolute maximum ratings of D13003K.

Absolute Maximum Ratings of D13003K
Pin No.	Pin Description	Pin Name
1	Collector-emitter voltage	400V
2	Collector-base voltage	700V
3	Base-emitter voltage	9V
4	Collector current	1.8A
5	Power dissipation	50W
6	Base current	0.9A
7	Operating and storage junction temperature range	-55 to 150C

• While embedding this chip into your project, make sure the ratings don’t exceed the absolute maximum ratings. Otherwise, it will put your entire project at stake.
• The junction temperature and storage temperature ranges from -55 to 150C.
• It is important to note that, don’t apply these ratings more than the required time, else they can affect device reliability.
• The collector-emitter 400 and collector-base voltage is 700. And total power dissipation is 50W which demonstrates that this device will release 50W energy during the working of this device.

D13003K Applications

D13003K is used in the following applications.

D13007K NPN Transistor Datasheet, Pinout, Power Ratings & Applications

Hello Fellas! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to D13007K. The D13007K is an NPN power transistor mainly used for switching and amplification purpose. This device is made of silicon material and falls under the category of bipolar junction transistors. As this is an NPN transistor so here major charge carriers are electrons. Holes are major carriers in the case of PNP transistors. This is a high voltage high current capability device used in energy-saving lamps. The collector current of this chip is 8A which means it is best for loads under 8A. And the power dissipation is 80W which projects it is eligible to release 80W power during the operation of this device. The collector-base voltage is 700V and collector-emitter voltage is 400 while the voltage across the base and emitter terminals is 9V which is the voltage needed to start the transistor action and bias the device. Read this entire post till the end as I’ll document the complete Introduction to D13007K covering datasheet, pinout, power ratings, working principle, applications, and physical dimensions. Let’s dive in.

Introduction to D13007K

• The D13007K is a power transistor that belongs to the NPN transistor family.
• The three terminals like emitter, base, and collector make this entire device. All these terminals are connected to the external electrical circuit.
• This is a current-controlled device because the small current at one terminal is employed to handle large current at the remaining terminals.

• While MOSFETs are voltage-controlled devices and come with terminals like a drain, source, and gate. The gate plays the same role in MOSFETs as what base plays in bipolar junction transistors.
• The bipolar junction transistors are mainly divided into two types one is PNP transistors and one is NPN transistors.

• Both electrons and holes play a key role in the conductivity of bipolar junction transistors.
• But in the case of PNP transistors holes are responsible for the major part of conductivity carried out inside the device while in the case of NPN transistors electrons play a key role in the overall conductivity inside the transistor.
• PNP transistors are considered less efficient than NPN transistors because electrons are quicker and efficient in the conductivity process compared to holes. The mobility of electrons is far better and quicker than the mobility of holes inside the transistor.

D13007K Datasheet

It is wise to check out the datasheet of the device before incorporating it into your electrical project. The datasheet comes with the main characteristics of the device. Click the link below to download the datasheet of D13007K.

D13007K Pinout

The following figure shows the pinout diagram of D13007K. The D13007K carries three terminals known as: 1: Base 2: Collector 3: Emitter All these terminals carry different doping concentrations. Which leads to the lack of symmetry of this device. The emitter side is highly doped and the collector side is lightly doped. While the collector side is 10-times less doped than the base side.

D13007K Working Principle

• The transistor working principle is straightforward and simple. It all initiates from the base side. When voltage is applied at the base side, it will bias the device, and as a result, the current will start flowing collector to the emitter terminal.
• As this is an NPN transistor so here current flow is carried out from the collector to emitter terminals this is the opposite in the case of PNP transistors.

• When voltage is applied at the base pin in PNP transitory, the current starts flowing from the emitter to the collector terminal.

• As described earlier this bipolar device is not symmetrical. Which means if you interchange both emitter and collector side then both terminals will start working in reverse active mode and the device will stop working in forward active mode.

D13007K Power Ratings

The following table features the absolute maximum ratings of D13007K.

Absolute Maximum Ratings of D13007K
Pin No.	Pin Description	Pin Name
1	Collector-emitter voltage	400V
2	Collector-base voltage	700V
3	Base-emitter voltage	9V
4	Collector current	8A
5	Power dissipation	80W
6	Base current	4A
7	Operating and storage junction temperature range	-55 to 150C

• While incorporating this device into your project, make sure the ratings don’t exceed the absolute maximum ratings. Otherwise, it can damage the entire project.
