How to obtain a bright and uniform coating

In the pyrophosphate copper plating process, in order to obtain a bright and uniform coating, in addition to maintaining the process parameters and plating solution, it can also be obtained by adding a copper pyrophosphate brightener. A suitable brightener can improve the brightness of the coating, produce a certain leveling effect, and also increase the working current density. Cu-203 is a product of Bigley, which is a copper pyrophosphate brightener that can produce bright and flat copper coatings, especially suitable for decorative electroplating. It has a wide range of current density and can be operated with high current density, which can shorten electroplating time and increase production capacity.
