FPC PCB Technics Capacity

Flexible PCB, FPCB, is a printed circuit board with graphics made of flexible substrate, consisting of an insulating substrate and a conductive layer, between which there can be a binder. between the insulating substrate and the conductive layer can have a binder. Because Flexible PC has a continuous automated production, high wiring density, light weight, small size, wiring error less, flexible and can be flexible to change the shape of Flexible PC is widely used in military, defense and consumer electronics such as digital cameras, watches, laptops and other fields.
