The Engineering Projects

Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new Proteus Library for Raspberry Pi 3 module. In my previous tutorial, I shared the Raspberry Pi Pico Library for Proteus. Similar to Pico Library, this RPi3 LIbrary won't operate on the Python code. We have just designed the front look to use in the circuit design. Although, we can upload Arduino code to these simulated Raspberry Pi boards.

This Raspberry Pi Proteus Library will have only the Raspberry Pi 3 board in it. We will design the other Pi boards soon. So, let's have a look at How to simulate Raspberry Pi in Proteus:

Raspberry Pi 3 Library for Proteus

First of all, we need to download the Raspberry Pi library files, by clicking the below button:

Raspberry Pi 3 Library for Proteus

Adding Proteus Library Files

• This Proteus Library zip file will have a folder in it, named "Proteus Library Files".
• Open this folder and you will find these two files in it:
• RaspberryPi3TEP.IDX
• RaspberryPi3TEP.LIB
• Next, we need to add these library files to the library folder of the Proteus software. So open C > PRogramin Files > Labcenter Electronics > Proteus 8 > Library folder and copy-paste these files into it.
• This zip file also has a Proteus simulation of the Raspberry Pi 3 board.

Note: Look at How to add a new Library in Proteus 8, if you are having any issues.

Raspberry Pi 3 in Proteus

• After adding the library files, open your Proteus software or restart it, if it's already open.
• In the components search box, make a search for Raspberry Pi 3 and you will get the below results:

• So double-click on this Raspberry Pi board to add it to your project.
• Place the Pi board in your Proteus workspace, as shown in the below figure:

Simulate Raspberry Pi 3 in Proteus

Now we are going to simulate this Raspberry Pi 3 board in Proteus. We will attach a simple LED to one of its pins. As I told earlier, we have just designed the exterior of this board. It won't read the Python code. We can use it to design circuit diagrams for our project. But just for fun, we have added the Arduino firmware to it. So, we can upload the Arduino hex file in this Pi board.

LED with Raspberry Pi 3

• I have connected a simple LED with resistance on Pin # 13 of the Pi board, as shown in the below figure:

• In the Properties panel of LED, change the Model Type from analog to digital, otherwise, it won't work.

Code for Raspberry Pi 3

• As I mentioned earlier, this Rpi3 board in Proteus won't read the Python code. We can only upload Arduino code in it.
• So, I am going to use the LED Blinking code and will select Arduino UNO in the boards' section, as shown in the below figure:

• Now compile the Arduino Code and get its hex file. Read this resource: How to Get the Hex File from Arduino IDE.

Add Hex File in Proteus

• In order to add this hex file, double-click on the Raspberry Pi 3 board to open its Properties Panel.
• In the Properties Panel, you will find a section named Program Files.
• Paste the hex file location in the Program Files section and click OK to close the panel.

Now, let's run our simulation to get the results:

Raspberry Pi 3 Simulation Results

• So, now let's run the simulation and you will see that the LED on the board will start blinking, as shown in the below figure:

So, that was all for today. I hope you will use this Raspberry Pi Library to design your projects. In the next tutorial, I will share the Raspberry Pi 4 Proteus Library. Till then, take care. Have fun!!!

An engineer's job description involves a great deal of creating things based on the knowledge learned in school and the course of their career. These creations qualify as creations of the mind which is the very definition of intellectual property and thus protectable under IP laws. 

So, understanding your rights as an engineer is critical to your profitability. This guide highlights types of intellectual property that have a huge significance to an engineer, such as patent, industrial design, trademark, copyright, and trade secret protections.

If you are venturing into a career as an engineer or have been in it but never paid attention to your IP rights, this will be an excellent read for you.

Understanding IP Laws

IP laws are designed to protect creations of the mind, also called intellectual property. The reasoning behind creating IP laws is to grant innovators and creators exclusive rights to their work, allowing them to commercialize and profit from them. 

Image source: https://pixabay.com/photos/engineer-engineering-teamwork-4941342/  

Also, the law creates avenues for rights holders to hold violators of their rights accountable for their actions, for example, by seeking compensation for damages suffered from their violation. Below is a breakdown of the important IP you need to know as an engineer. If you have intellectual property law questions, an expert Canadian IP attorney from Heer Law will gladly answer your questions and help you navigate a problem if you have one.

Patents

Patents are arguably the most important type of IP protection for engineers. Patents cover new innovations in the engineering industry , including construction methods, materials, building processes, new fuel technologies, new engines, etc. 

For an idea to qualify for patenting, it must meet the eligibility criteria. First, the idea must be novel, meaning it must be new in the world and never be revealed at any place before the date of filing for registration. The idea must also be practical for two other engineers in the same field. 

Lastly, the patent applicant must provide the registering entity with detailed information about the idea so that another person skilled in the trade can replicate the idea following the information provided. The government holds this information in confidentiality until the expiry of the patent protection period, which is 20 years from the filing date for registration.

Industrial Design Protections

Industrial design protection, also known as design patterns in some countries, is a form of patent protection covering a product's nonfunctional aspect. In other words, it covers a product's ornamental or aesthetic aspects, such as shape, ornamentation, texture, feel, etc. 

For a design to qualify for industrial design protection under Canadian intellectual property law, the design must be new and not closely resemble an existing one, must apply to a specific product, and has to be nonfunctional in the sense that it doesn't affect the performance and efficiency of a product in any way. 

Industrial design protections can apply to creations like car design, building design, interior design, and décor and are enforceable for 15 years from the filing date for registration. 

Trademark Protections

A trademark is a word, symbol, logo, slogan, hashtag, or combination of any distinguishing goods and services in the market. As an engineer, your work may not be so much about selling products but for other services, in which case trademarking your name and your business name and brand becomes critical for marketing purposes and building brand reputation. 

Trademarks can apply on a first-to-use basis, meaning you can claim ownership of a trademark even if it's not registered; however, proving ownership can be challenging. The best practice is to register your trademarks with the relevant authority. 

Upon successful registration, trademark protections run for ten years from the registration date. However, the term is renewable upon payment of a service fee, allowing businesses and individuals to claim ownership of a trademark indefinitely.

Copyright Protections

Copyright protections apply to creative work such as pictures, art, text, music, and video. Engineering involves creating some designs from scratch, so you need to make sketches called draw plans as the foundation of your creations. Those sketches and plans are protected under intellectual property law. 

In most countries, including Canada , the author of creative work owns its copyright by default unless they expressly transfer them to their clients. Therefore it's important to ensure that the terms of your contract are clear to avoid IP rights conflict with clients. 

Copyright protections last for the author's lifetime and 70 years after death. If more than one author was involved, the 70 years starts running after the death of the last surviving author. If a business owns the copyright, it lasts 95 years from publication or 120 years from the date of creation, whichever is shorter.

Trade Secrets

Trade secrets are, just as the name suggests, confidential information that gives a business a competitive edge in the market. A trade secret for engineers can include the formula for creating a specific building material, processes involved, or business plans. 

An entity does not need to register trade secrets to make them enforceable. However, doing so makes proving that information is a protected trade secret easier. Under the law, a trade secret can only be recognized as enforceable if the right holder makes reasonable efforts at protecting it, for example, by limiting access to good information, having employees sign non-disclosure agreements, and using passwords in encryption to secure the information. Also, trade secret protections run indefinitely if the rights holder keeps it confidential. 

Significance of IP Registration

IP laws guarantee a person or entity's right to profit from their creation through exclusivity. For example, patent rights give the rights holder the exclusive right to sell their innovation, allowing them to set the prices for their innovation without fearing being undercut. Where the demand exceeds demand, they can sell rights to other entities expanding their income streams. So if for no other reason, the money factor should motivate you to secure your rights.

The assurance of profit-making from inventions and creations has been critical in spurring innovation. Investors want to be sure they get value for money, and the only way of getting assurances is guaranteed exclusivity to profit from inventions and creations. Some experts feel that IP laws, in a way, hinder innovations because it prevents others from building upon what has been already created, but the gains achieved through the laws outway the drawbacks by far. 

Hello friends, I hope you all are fine. In today's tutorial, I am going to share the Raspberry Pi Pico Library for Proteus. It's a dummy library, we have just designed the display. We can't add the Python Code to it, but we can make it work with Arduino code. A mixture of Arduino and Raspberry Pi, I have given it an unofficial name "Arduino Pi". It's better to have something than nothing. You can design circuit diagrams using this library and can also demonstrate your project in presentations by designing simulations.

So, let's have a look at How to simulate Raspberry Pi Pico by adding this Proteus Library:

Raspberry Pi Pico Library for Proteus

Hello friends, I hope you all are doing well. In today's tutorial, I am going to share a new Proteus Library of ESP32 embedded module. ESP32 is a microcontroller board used mostly in IoT projects. It's a successor of ESP8266 or NodeMCU. We have already shared the NodeMCU Library for Proteus and I hope you guys have enjoyed it.

Proteus software is not capable of handling WiFi or BLE technology, thus we can't implement these technologies in the ESP32 board. Though, you can use its input/output pins to interface embedded sensors and modules. You can also use it to design the Circuit Diagram of your Project.

So, let's have a look at How to simulate ESP32 board in Proteus:

Hello friends, I hope you all are doing great. In today's tutorial, I will share a Proteus Library of another embedded module i.e. NodeMCU. NodeMCU is a microcontroller board and if you are new to this board, you should read Introduction to NodeMCU to get your hands dirty. NodeMCU is not present in the components library of Proteus and using this library you can easily simulate NodeMCU in Proteus.

We can't add WiFi and BLE capabilities to our module in the Proteus software, that's why it will just perform the basic functions i.e. sensors interfacing, PWM, I/O control etc. So, you can use it for simple code testing and can also use it to design circuit diagrams of your projects.

Hi Friends! Hope you’re well today. Today, I am going to share the Proteus Library of Current Sensor WCS1600. This sensor is not available in the Proteus Components Library and we’re sharing it for the first time.

The Current Sensor WCS1600 is used to measure the current flowing through the circuit and is used in embedded systems and robotics projects. If you are new to this sensor, you must first design its simulation before playing with the hardware. 

Before we move further, let’s have a brief overview of WCS1600 Current Sensor:

What is WCS1600 Current Sensor?

WCS1600 comes with a drift linear hall sensor IC which gives precise and accurate values. The hall sensor IC is 9.0 mm in diameter through the hole and is incorporated with a temperature compensation circuit. To measure the passing current, the electric wire of the system should pass through the hole of this sensor.

Using this design, the system designers can monitor the current path of any length without affecting the layout of the original system. The integrated hall IC senses the magnetic field generated when current flows through the wire. That magnetic field is then converted into a proportional voltage.

Features:

• Product: WCS1600 current sensor.
• Sensitivity: 22mV/A
• Low operating current: 3mA
• Supply Current: 3.5 ~ 6mA
• Zero Current Vout: 2.5V
• Bandwidth: 23kHz
• Isolation voltage: 4000V
• Supply Voltage: 3 ~ 12V
• Operating Temp: -20 ~ 125°C
• Conductor Through Hole: 9.2mm
• Temperature Drift: +/-0.3 mV/C
• Output voltage proportional to AC and DC
• Wide sensing current range 0~100A at 5V volt
• For easy soldering on PCB, two bronze sticks are used
• Ratiometric output from the supply voltage

WCS1600 Current Sensor Library for Proteus

• First, download the Proteus Library zip file for WCS1600 Current Sensor by clicking the link below:

WCS1600 Current Sensor Library for Proteus

Adding Library Files

• After downloading this zip file, extract it and you’ll find the folder "Proteus Library Files".
• In this folder, 3 Proteus Library files are available, named:
• WCS1600TEP.HEX
• WCS1600TEP.IDX
• WCS1600TEP.LIB
• Copy these files and paste them into the Library Folder of Proteus Software, as shown in the below figure:

• After adding these files to the Library folder, open the Proteus Software, and if you’re already working on it, you need to restart it. 

Note: You should read How to Add Library in Proteus 8, if you are having any issues finding the Library Folder.

Current Sensor in Proteus

In the components section, write ‘WCS1600 Current Sensor’ in the search bar and you’ll get the following result:

Now place this sensor in the Proteus workspace, as shown in the below figure:

You can see in the above figure, this current sensor carries 4 pins as follow:

• Vcc: 5V is provided to this pin.
• GND: This pin is grounded.
• D0: This is the output pin and it goes HIGH when current passes through the hole and will remain LOW when there is no current.
• A0: This pin will give the analog output.
  
• TestPin: As we can't use a current wire in Proteus, so we placed this test pin to indicate current. When this pin is HIGH, means the current is passing through the IC and if it's LOW, means no current. 

Adding Hex File

Now double-click the sensor to open up its Properties Panel, as shown in the below figure:

Go to the ‘Program File’ section and browse for the file WCS1600TEP.HEX which you have already downloaded and placed in the Library Folder of Proteus.

Simulate Current Sensor

• Now we’ll design a simple circuit to use this WCS1600 Current Sensor in Proteus.
• The following figure shows the WCS1600 Current Sensor Simulation in Proteus.

• As you can see in the above figure, I have placed an LC circuit at the analog pin, that's only for the simulation to get the analog value. It won't be used in real hardware.
  
• Now run Proteus Simulation. You’ll get the result as shown below.

That’s all for today. Hope you’ve found this Library for Proteus useful. If you’re unsure or have any queries regarding the simulation of this sensor and how to use it in your engineering projects, you are welcome to get in touch with me in the section below. I’ll help you the best way I can. Thank you for reading this tutorial.

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. 

1. FR-4
2. Teflon
3. Metal

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.

FR-4 Manufacturing

• PCBway Fabricaton House manufactures high-quality FR4 PCBs. They can produce these PCBs really fast. The cost is also optimum. They are capable of making multi-layered FR4 PCBs.

Here are some samples of FR4 PCBs made by PCBway.

Here are some common FR4 PCB assembly mounting technology types:

1. Surface Mount Technology (SMT):

 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.

2. Through-Hole Technology (THT):

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.

3. Mixed Technology: 

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.

4. Chip-On-Board (COB):

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.

5. Ball Grid Array (BGA):

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.

6. Micro BGA (uBGA):

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:

1. Design:

 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:

2. Gerber File Generation: 

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:

3. Material Selection:

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:

1. Dielectric Constant (Dk): The dielectric constant of the FR4 material affects the impedance and signal propagation characteristics of the PCB. Higher Dk values result in slower signal speeds. Consider the specific requirements of your circuit design. Select an FR4 material with an appropriate Dk value.
2. Glass Transition Temperature (Tg): Tg is the temperature at which the FR4 material transforms from a rigid state to a soft, rubbery state. Higher Tg values indicate better heat resistance and mechanical strength. Ensure that the chosen FR4 material has a Tg value that can withstand the expected operating temperatures of your PCB.
3. Copper Foil Thickness: Copper foils are added to the FR4 material. The thickness of the copper foil affects the current-carrying capacity of the PCB. It also affects the PCB’s thermal performance. Thicker copper foils can handle higher currents. However, they may require more complex fabrication processes.
4. Layer Count: Determine the number of layers required for your PCB design. FR4 materials are available in various layer configurations.  Single-sided, double-sided, and multilayer are among those. Consider the complexity of your circuit design. Choose an FR4 material that supports the required number of layers.
5. Surface Finish Compatibility: There are different kinds of surface finishes. For example-

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.  

6. 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:

• a) UL Recognition: Underwriters Laboratories (UL) is a globally recognized safety certification organization. They provide testing and certification services for electrical components and materials, including FR4 laminates. UL recognition ensures that the FR4 material meets specific safety and performance criteria.
• b) ISO Certification: The International Organization for Standardization (ISO) sets globally recognized standards for various industries. Suppliers with ISO 9001 certification indicate that they have implemented quality management systems to ensure consistent product quality.
• c) RoHS Compliance: The Restriction of Hazardous Substances (RoHS) directive restricts the use of hazardous substances in electrical and electronic equipment. FR4 materials should comply with RoHS regulations to ensure they do not contain restricted substances such as lead, mercury, cadmium, and others.

Industry Standards:

• a) IPC Standards: The Institute for Printed Circuits (IPC) develops and publishes industry standards for PCB design, manufacturing, and assembly. IPC-4101 is a standard that defines the requirements for base materials, including FR4 laminates. It specifies material properties such as dielectric constant, thermal conductivity, and flame resistance.
• b) NEMA Standards: The National Electrical Manufacturers Association (NEMA) sets standards for electrical equipment and materials. NEMA LI 1 is a standard that defines the performance requirements for laminated thermosetting materials, including FR4.
• c) MIL-PRF-55110: This military specification outlines the requirements for rigid printed wiring boards used in military and aerospace applications. It includes specific requirements for FR4 materials. Those are mechanical properties, electrical performance, and environmental durability.
