FPC is made of polyimide material and etched copper conductors. ... Single-sided flexible circuits have a single conductor layer made of either a metal or conductive (metal filled) polymer on a flexible dielectric film.
A flexible printed circuit consists of a metallic layer of traces, usually copper, bonded to a dielectric layer, usually polyimide.
Double-sided flex circuits are flex circuits having two conductor layers.
