In this article you will learn everything you need to know about printed circuit board (PCB). Printed circuit board is most very important for electronics engineers to make electronics circuits. Electronics and Electrical engineers usually ignores the importance of technique and many engineers don’t even know what printed circuit board exactly is? If you don’t know anything about it, this article will help you to get useful knowledge related to it and its designing. I have also included Video tutorials at the end of this article . These video tutorials are all about how to design printed circuit board using proteus software.
In this article you will learn:
- What is a printed circuit board ?
- Layers of printed circuit board? Copper side of printed circuit board ?
- what are traces in printed circuit board and how to select their width?
- Video tutorials training for PCB designing ?
What is a printed circuit board or PCB:
As the name suggests of Printed circuit board, it is board on that circuit is print with the help of some procedure. It is a type of board which connects various components together with the help of copper traces on board. It is made of a copper. A proper procedure is used to print circuit on that board I will discuss procedure in video tutorials with practical examples. Before the invention of Printed circuit board circuits were made with connecting wires which was very hectic and long process to make any circuit. With the invention of this technique, you can even make a this board at your home with very ease. These board are widely used in electronics devices like computer mother board, your mobile board and even every single electronics device have printed circuit board inside. Diagram above shows a power supply printed circuit board.
What are layers in PCB Designing?
Layers are most important key points in its designing. It can be made with up to 12 layers. But maximum circuits available in market are single layer. Now the question come into someone’s mind what is a layer? To better understand what is layer, have a look at pictures shown below:
As shown in above picture, there are traces of copper which are used to connect components to each other and it is basically a layer of board. The above diagram is a single layer board. Because it has copper layers only on one side of board and other side of above board is for placement or assembly of components. I will discuss in video training how to make such boards. The diagram below shows the top view of a board where we place components and it is called top silk of printed circuit board.
What are traces in PCB and how to select their width ?
Traces are made of copper which are used to connect point with each other and other words the lines through which current flow from one point to another point as shown in above figure number one. There are usually two types of traces :
- Signal Traces
- Power Traces
Signal traces width is small and power traces width is bigger and its depend on amount of current flow through these power traces. Signal traces are usually small in width. Because current flow through these traces are usually in mili Amperes. Now the question is how to select width of traces according to magnitude of current? I will answer this question in video tutorials which are given at the end of this article. Diagram shown below, shows the power and signal traces of board. Yellow arrow indicates signal traces and black arrow indicates power traces.
Video Tutorial on PCB designing using Proteus ARES :
In these video tutorials you will learn how to make it in Proteus ARES software. There are many software available for PCB designing like Orcad, Eagle, express PCB. But if you are beginner in designing, I recommend you to use Proteus ARES. Because it is easy to use software for printed circuit board designing.I will also post articles on Eagle , Orcad for its designing in coming weeks. I assure you that after watching following video tutorials, you will be able to make your own board.But to become professional in circuit designing, you must practice different examples. Good luck 🙂
Tutorial number : 1 Basic overview of PCB designing and schematic diagrams
