Description

Technical Field

[0001] The utility model relates to the field of copper plating working solution preparation, in particular to a pulse copper plating working solution preparation device. Background Art

[0002] A copper plating solution is a chemical substance used to coat copper plates or other metal surfaces with a copper film. Copper plating is achieved by electrolyzing a liquid containing copper ions onto the surface of another object. The working principle is to utilize electrochemical principles to connect an anode (which produces Cu2+ ions) with a cathode (copper plate or other metal) in an electrolytic cell. A certain potential and current are then applied to reduce the ions at the anode to the cathode surface, thereby achieving the copper plating process. Chinese invention patent application number 202311675865.3 discloses a pulse copper plating solution, a preparation method thereof, and a pulse copper plating method. The pulse copper plating solution is prepared by mixing the copper sulfate, sulfuric acid, chloride ions, a starter, a brightener, and a tank opener.
