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 Electrochemical Effects of Immersion Gold on ...

Electroless Nickel - Immersion Gold (ENIG) has become one of the more extensively used plating methods in the microelectronics industry for creating an under-bump-metallurgy (UBM) [1-3]. Several reasons for this are: low cost, high throughput, and simplicity of the process, i.e. no photolithography, no high vacuum steps, and no current is applied as is the case for electroplated UBM layers [4 ...

nickel/immersion gold (ENIG) process. To avoid cracking of the nickel during bending, the use of ENIG for flex and rigid-flex circuits has typically required a relatively thin electroless nickel deposit of medium phosphorus content. In this technical paper, the reliability of ENIG with high-phosphorus electroless nickel is examined for such applications. Using electroless nickel deposits of ...
