Abstract
A process for the surface treatment of beryllium copper prior to electroplating comprising degreasing the material, removing beryllium from the surface thereby leaving a copper-rich surface and activating the copper-rich surface for electroplating. The removal of the beryllium is accomplished by causing the beryllium to form compounds and then dissolving the compounds without dissolving the copper.
