Most electroless gold plating processes require a separate gold immersion deposit, which provides adhesion for the subsequent gold layer and avoids contamination of the gold plating bath, particularly by nickel. 37 In a study conducted by Ikuhiro et al., 15 the plating process of gold consists of two steps. The first step is immersion gold to ...

Mar 01, 2002· For example, using dc, electroplated gold completely covers the surface and will be porefree at a nominal thickness of µm. With pulse plating, the gold covers the same surface and will be porefree at a thickness of µm, reducing production costs. Gold bump plating. Another example from the semiconductor industry is gold bump plating.

Gold is typically thought of as a metal used for coins and jewelry. However, its resistance to corrosion, conductivity and malleability makes it useful for electronics. When electronics become defective, there are ways to recover the gold, such as reverse electroplating. Reverse electroplating ...
