Understanding PCBs

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.
