Double-Layer FPC
Double-Layer FPC
A double-sided flexible printed circuit (Double-sided FPC) is a flexible electronic component with conductive traces routed on both sides of the substrate. Building on the thinness and flexibility of single-sided FPCs, it enables electrical interconnection between the two layers via plated through-holes (PTHs) or blind vias
