Printed circuit board with components attached. A printed circuit board (PCB) is a plastic board made for connecting electronic components together. These are used in almost all computers and electronics today. The card is made of a material that does not conduct electricity, like fiberglass or plastic.
Chemical structure of PCBs. The possible positions of chlorine atoms on the benzene rings are denoted by numbers assigned to the carbon atoms. PCB warning label on a power transformer known to contain PCBs. A polychlorinated biphenyl (PCB) is an organic chlorine compound with the formula C12H10âxClx. Polychlorinated biphenyls were once widely deployed as dielectric and coolant fluids in electrical apparatus, carbonless copy paper and in heat transfer fluids.
