Printed Circuit Materials (PCB / PWB)

Printed circuit materials have copper-clad surfaces for the fabrication of electronic and electrical circuitry on printed circuit boards (PCBs), printed wiring boards (PWB) and flexible circuits. They include materials for flexible film circuit and membrane switches, as well as rigid laminates for circuit boards. Specifications for printed circuit materials include dimensions such as width, length and thickness; thermal properties; physical and mechanical properties; and electrical parameters.
