ELECTROPLATING APPARATUS

摘要

Electroplating apparatus for applying a protective metallic coating on the surface of an object has chamber means which includes a process chamber containing at least a part of the liquid electrolyte solution and in which the object to be seated is submerged. Atmospheric air is prevented from flowing through the process chamber, and a pneumatic pressure-reducing pump is connected to the chamber means to maintain a reduced pressure, which is substantially below atmospheric, above the electrolyte solution within at least a part of the chamber means.
