Abstract
A FPCB includes a base layer defining at least one first through hole. A conductive paste block is formed in each first through hole. Each conductive paste block includes a first and a second end portion. The base layer has opposite surfaces, and a first conductive wiring layer is formed on each surface of the base layer. The first end portion at least protrudes from the base layer and is exposed from the first conductive wiring layer. An insulating layer and a second conductive wiring layer are formed on each first conductive wiring layer. At least one second through hole is defined in each insulating layer. The second through hole positioned near the first end portion extends to the first end portion and forms a recess. A conductive via is formed in each second through hole and the corresponding recess, and is electrically connected to the conductive paste block.
