Electronic Gold Plating Methods

Each type of industry using electronics plating has developed its own gold plating bath recipes. Most desire to minimize the amount of gold used, for obvious reasons, but still retain the best thickness of the plate to prevent corrosion. They are also concerned with minimizing the amount of bath solution while making it as pure as possible, and making the process occur quickly. Electronics plating, also called industrial plating, is broken down into four categories or types of gold used. They are soft and pure gold used on semiconductors, hard and bright gold used for contact points and connectors, hard and bright gold used on printed-circuit tabs and soft and pure gold used in chip-on-board products, which involves plating the whole circuit board.
