Definition and Classification of PCB
Sep 18, 2016

PCB is short for Printed Circuit Board. Usually we called printed circuit which put on the insulating base, according to the predetermined design, and make it into conductive pattern. And on the insulating base to provide electrical conductive patterns between components which called printed line. Such finished plate printed circuit or printed circuit called the printed circuit board, also known as printed boards or printed circuit board.

According to the nature of the substrate, PCB is divided into rigid PCB and flexible PCB. The substrate of the rigid PCB is composed of glass cloth, prephenolic or epoxy resin, CCL surface one or two copper clad laminate and then glue solidified into the substrate. Flexible substrate is usually for soft film (flexible insulating substrate), a conductive pattern printed on the printed circuit board, we called it flexible printed circuit board.
