An Overview of Immersion Gold ENIG Surface Finish for

20-06-2017  Although ENIG is an expensive surface finish technology, still it is popular due to the following reasons: Immersion gold has strong chemical properties. These properties include impressive wettability, surface planarity, coplanarity, and long shelf life. The properties are contributed by

Electroless nickel immersion gold - Wikipedia

Electroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, 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 oxi

The immersion gold step of any ENIG process relies on the exchange of nickel ions for gold, which is essentially a corrosion action. To compensate for the lower ductility of medium-P electroless nickel deposits, some fabricators of flexible PWBs finished with ENIG deposit a relatively low nickel thickness (2-3 microns) in comparison to deposits on

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.
