The present invention relates to a flexible printed circuit board substrate and FPCB made from the flexible printed circuit board substrate. In one embodiment, a flexible printed circuit board substrate includes a dielectric layer, a rolled copper foil and an electroplated copper foil disposed on two opposite surfaces of the dielectric layer respectively. The contact fingers are made from electroplated copper foil, as a result, the contact fingers are stronger than that made from rolled copper foil. Furthermore, electroplated copper foils are cheaper than rolled copper foils.
