Chemical copper plating
Gold plating is a method of depositing a thin layer of gold on the surface of glass or metal, most often copper or silver. Gold plating is often used in electronics, to provide a corrosion-resistant electrically conductive layer on copper, typically in electrical connectors and printed circuit boards. With direct gold-on-copper plating, the copper atoms ha… WebGeneral activities include but are not limited to: electroplating of various metals (including Copper Damascene, sulfite bath chemistry Gold plating, and Nickel plating), plating bath chemical maintenance, thin film analysis/inspection, measurement and data entry.
