Maybe you often hear PCB products,so do you reall know what PCB is. Actually,it is a board base which physically supports and wires the components of electronic devices. And most PCBs are made from fiberglass or glass-reinforced plastics that come with copper traces. As for various electronic devices,they have different types of PCBs. Usually,simple devices usually have one layer PCBs but complex devices even have 12 layers. By the way,although PCBs are green,they can come in almost any color.
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.
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.
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.
