Abstract:
A process of plating on isolated conductor circuit pattern wherein a deposit is formed through an electroplating on an isolated conductor circuit pattern of wiring circuit board, characterized in comprising the steps of forming on the wiring circuit board an electrically conducting layer consisting of a material electrically conducting and peelable with one of heat, solvent and alkali, so as to be at least in contact with the isolated conductor circuit pattern on which a deposit coat is to be formed; forming a peelable protect layer on at least a portion of the electrically conducting layer other than a portion on which the deposit coat is to be formed and to be superposed on the electrically conducting layer; causing a metal to deposit on a portion not coated by the protect layer through an electroplating performed with the electrically conducting layer used as a power supply layer; and peeling off the electrically conducting layer and the protect layer left on the wiring circuit board.
