PCB Process: ENIG - Electroless Nickel Immersion Gold ...

“RAIG” Immersion Gold. TWX-40 reduction assisted immersion gold is a single-step bath that plates up to 4-8 μin gold with zero nickel corrosion or porosity. TWX-40 is a unique process, with autocatalytic capability; this makes it the most gentle bath for nickel underlayers.TWX-40’s primary advantage is that it assures compliance with IPC 4552 rev. A.

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
