Reddish immersion gold
WebENIG (electroless nickel immersion gold) is a two-layer metallic surface finish that consists of a very thin layer of gold plated over a layer of nickel. Using an electroless chemical reaction, a nickel layer is first plated on copper pads. An immersion method is then used to apply gold on top of the nickel layer to cover the pads and traces. 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 containin…
