A PCB is a board base that physically supports and wires the components of electronic devices. Most PCBs are made from fiberglass or glass-reinforced plastics that come with copper traces.
Different electronic devices have different types of PCBs. For example, simple devices usually have PCBs that are made up of one layer; however, complex devices such as computer graphic cards and motherboards have PCBs that are up to 12 layers. Although, PCBs are green in color, they can come in almost any color.
Advantages of PCBs
There are many advantages that come with PCBs. One of the main advantages is that they are very neat and great to look at. Before, the components in an electronic device were connected using large wires that were randomly placed where they could fit. This is no longer the case as the wires are now professionally connected in a neat way.
The components are mounted on a non-conductive board and connected using traces. Since PCBs are designed on a computer, you can easily fit many components within a small space.
Parts of A PCB
A PCB has many parts. When you look at it you will be able to see thin lines that connect all the components in the circuit. These thin lines are the ones that replaced the much larger wires that were used in the past.
In addition to the thin lines, there are tiny holes that are usually drilled where you should place any component that you need. For example, if a microchip is part of the circuit and requires eight connections, you will find the same number of holes on the PCB. Presence of the holes ensures that you are able to mount the necessary components fast. The holes also help you to save a lot of space.
The final parts of the PCB are the components. These are small devices that must be linked to the PCB in order for it to work. Common components include: diodes, resister, switches and microchips.
How to Take Care Of PCB
For the PCB to last for a long time you need to take good care of it. When handling it always ensure that you wear rubber-soled shoes in order to prevent a buildup of static electricity that could harm the PCB. To discharge any residual electricity that might be stored in your body you should first touch a piece of metal for at least two seconds.
