What Do PCB Design Services Do

By Linda Maynard


Many view electronics as little more than modern day witchcraft, as they can't actually see how things work. It can be confusing to the majority but where would modern day man be without electronics. So if you don't know a resistor from a capacitor, but still need electronics in your device it makes sense to use professional PCB design services.

Electrical devices abound in this age of technology, and seem to be everywhere you look. They are in the work place, and in the home, they are also there as you travel between the two. Some are bigger than others, but they do have a common bond, inside them there will be printed circuit boards.

If ever you open a device and look inside you will notice these printed circuit boards. Quite often they are either brown or green in color. They seem to have an awful lot of components on them, and this is where people begin to get baffled.

The easy thing to do is to think of an electronic system, as a miniaturised electrical system. Power goes in, it does something and comes out again and goes to earth. In much the same way as a simple lighting circuit, power comes in, you operate the switch completing the circuit, the power goes through the filament illuminating the bulb, and out to earth.

It does look very confusing to the average person. Mainly because they don't recognise the components, or understand what they do. It also seems to be very small, and crammed in together.

The board itself is made from material layers bonded together to a uniform thickness. You will often notice small metal tracks on one side, these are used to conduct the current to where it is meant to be. On the other side you will see the components, sitting above a white etched layout plan.

This layout plan is a circuit that has been devised to carry out the operation that a customer wants. It also tells the engineer which device has to be placed where for the circuit to operate properly. They will also be working from a large paper schematic too, so the engineer will be checking off one against the other.

As soon as the proposed circuit has been worked out in theory, a full size version needs to be created. The correct size board is made so that the right component will sit in its correct place and it is then soldered permanently in position. This carries on until all components are correctly fitted. This allows full testing to be carried out, which will include whether it can fit in the designated position without anything fouling.

So although these electronic boards might not be as daunting as they first appear, it is all to easy to become confused by them. It is a sensible option to remove that confusion and make use of professional PCB design services. They are the experts, and will be able to do things faster and cheaper than others.

  1. With the growth of electronic technology in lighting and automatic lighting, there are various new things been developed and they are energy efficient as well. As, if we talk about PCB Assembly Services, then it can also be a good example.
