Double sided flexible printed circuit
Double sided flexible printed circuit consists of two copper layers on a flexible dielectric film, normally connected with the plated through hole (see picture below). Double-sided flexible PCB can be produced with or without cover layers.

Such double sided flexible printed circuit applications and advantages is almost the same as single-sided flexible PCB, its main advantage is to increase the wiring density per unit area. It can be classified as the following:
- without plated through hole and without cover layer
- without plated through hole but with cover layer
- with plated through hole but without cover layer
- with plated through hole and with cover layer
P.S.: It is occasionally happen without cover layer of double-sided flexible circuits.
