PCBs are used in almost all electronic devices. Printed circuit boards route signals through electronic devices, providing both mechanical and electrical connections.They are sometimes confused with printed wiring boards, or PWBs, but unlike PWBs, PCBs have circuit elements manufactured into the nonconductive substrate of the board. And PCB has a wider range of application in many fields.
