A rigid printed circuit board (PCB) is a flat, inflexible board made from solid substrate material — most commonly FR4 fiberglass — onto which conductive copper traces are etched to electrically connect components. Unlike flexible PCBs, rigid boards maintain their shape permanently. They are the most widely used PCB type in electronics, found in computers, medical devices, automotive systems, and telecommunications equipment.
