Copper foil is a type of anionic electrolytic material, which is a thin, continuous layer of metal foil deposited on the substrate layer of a circuit board. It serves as a conductive material for PCBs. It is easy to adhere to the insulation layer, accept the printed protective layer, and form a circuit diagram after corrosion.
