Technical Field

Background

Electroplating is a process of plating a thin layer of other metals or alloys on the surface of some metals (which can be conductive films) by utilizing the principle of electrolysis, and in the continuous electroplating process, the plating layer is gradually thickened, and correspondingly, the conductive capability of the films is also gradually enhanced.

At present, when a plurality of electroplating baths connected in series continuously electroplate a conductive film, the depth of each electroplating bath is the same, the height of an electroplating anode is the same, and correspondingly, the effective electroplating distance is also the same.

The electroplating anodes have the same height, which is a waste for electroplating the front end because the front end plating layer is thinner and the conductive capability is weaker, so that a large current is not needed to be applied to the conductive roller, and a longer effective electroplating distance is not needed;
