Electroless Nickel Immersion Gold (ENIG) Nickel Gold Plating

Electroless Nickel Immersion Gold (ENIG) plating is a surface plating process that occurs when electroless nickel plating is covered with a layer of gold. The gold is added to act as a protective barrier to safeguard the nickel plating from oxidation.

Uyemura's Direct Immersion Gold process deposits a thin coating of immersion gold directly on the copper substrate. It is the best choice for a solderable surface, eliminating the shortcomings of other finishes. It is ideally suited for "lead free" higher temperature assembly conditions. The gold coating is 1 2 micro inches (0.02 0.05 microns).

Nov 01, 2000In an immersion process you have a galvanic displacement in which a metal less noble, for example copper or nickel, is displaced by gold. As soon as the copper or nickel surface is no longer exposed, the process stops. A true immersion deposit is limited in thickness and typically does not adhere extremely well to the substrate.
