Commonly known as PCBs (printed circuit boards), circuit boards consist of an insulator (usually fiberglass), with threads of conductive material serving as wires on the base of the board. The insulator may consist of one or numerous layers of material glued into a single entity. These additional layers may serve a number of purposes, including providing grounding to the board.
