Background

In the electroplating, plating metal or other insoluble materials are used as an anode, a workpiece to be plated is used as a cathode, and cations of the plating metal are reduced on the surface of a plate to be plated to form a plating layer. In order to eliminate the interference of other cations and make the plating layer uniform and firm, a solution containing metal cations of the plating layer is used as an electroplating solution to keep the concentration of the metal cations of the plating layer unchanged, thereby realizing the plating of the metal plating layer on the plate to be electroplated and changing the surface property or the size of the plate.
