Determining plating type and and what kind of dc power supply the plating tanks shall use is the implementation and the first important work in electroplating production. There are 2 methods to determine suitable dc power supply in the actual plating production: One: according to plating liquid solution to determine volume current density; Two: calculated according to the plating area to get plating current density per unit.
