Circuit board. Macrophotograph of a printed circuit board (PCB). A circuit board consists of tracks of a metal conductor (pink) on a board made of insulating material, which form a circuit with connection points (blue circles). A number of components can be attached at the connection points, including resistors, transistors, microchips, dials and switches. Circuit boards are used in most electronic products, including computers and mobile phones.
