FPC Manufacturing Process Overview Substrate PreparationPolyimide (PI) or PET films are selected as the base material. They are cleaned and dried to ensure a dust-free and oil-free surface. Circuit PatterningCopper is patterned onto the substrate through etching or plating, forming the required conductive traces. Drilling & PlatingHoles are drilled where interconnections are needed, followed by […]
