Electroless nickel immersion gold - Wikipedia

Electroless nickel immersion gold (ENIG) is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes. It consists of an electroless nickel plating covered with a thin layer of gold, which protects the nickel from oxidation. The gold is typically applied by quick immersion in a solution containing gold salts. Some of the nickel is oxidized to Ni while the gold is reduced to metallic state. A variant of this pr

The Electrochemical Effects of Immersion Gold on ...

The electroless nickel and immersion gold layers are deposited using a series of wet chemical baths. The wafers are first immersed in chemicals that clean the bond pads of any impurities and then in chemicals that activate the pad surface for selective deposition of the nickel. This activation is typically a “zincation” process fo r aluminum pads and palladium process for copper pads. The nickel selectively

Electroless Nickel Immersion Gold (ENIG) ENIG is a two layer metallic coating of 2-8 μin Au over 120-240 μin Ni. The Nickel is the barrier to the copper and is the surface to which the components are actually soldered to. The gold protects the nickel during storage and also provides the low contact resistance required for the thin gold deposits.
