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. ..»
