What are PCB boards?
PCB stands for “printed circuit board.” It is a thick sheet, usually made of glass fibers, that contains circuits that have been printed onto the board. This technology is used for motherboards, peripheral cards and most storage devices.PCB MaterialsA PCB is typically made of several layers of glass fibers that have been glued together with epoxy resin. The glass fibers allow the board to respond to temperature without damaging components.Temperature and PCBsHeat causes a PCB to expand, and cold contracts it to its original shape. The flexibility of glass fibers prevents the board from cracking when temperatures or temperature changes become extreme.PCAsA PCB that contains electrical components, like a motherboard, is referred to as a “printed circuit assembly.” The PCB itself is just the epoxied layers of fiberglass.Putting Circuits in BoardsThere are several methods for creating copper circuits or “traces” on a board. Most of them involve putting a thin sheet of copper against the bo
