[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. Electroplating is also an important process used in the processing of PCB boards. During the electroplating process, it is necessary to continuously add reagents to the electroplating tank.
