Electroless nickel immersion gold (ENIG) is a type of surface plating used for printed circuit boards. It consists of electroless nickel plating covered with a thin layer of immersion gold, which protects the nickel from oxidatio n. The thickness of gold during this process usually is 3 5 micro inch, the thickness of Nick is around 150 250
• Electroless Ni layer of 120 – 240 #181;” deposited on the copper surface. • Coated with an electroless palladium layer (4 to 20 #181;”) • Topped with immersion gold (2 to 8 #181;”).
