Gold plated parts next to a ruler
Electroless Nickel Immersion Gold (ENIG) is a surface plating process that occurs when electroless nickel plating is covered with a layer of gold. The gold is added to act as a protective barrier to safeguard the nickel plating from oxidation. The prevention of this chemical reaction is why ENIG plating has become widely popular for preserving the nickel layer prior to soldering.

ENIG PLATING PROCESS

INCERTEC has developed a specific proprietary chemistry to successfully deposit this autocatalytic coating onto typical alloys. The thin immersion gold layer prevents a layer of oxide from forming on the electroless nickel layer. This ensures good stability. The chemistry can deposit on the following:

  • • Stainless steel
  • • Steel
  • • Alloy 42 & alloy 52
  • • Kovar
  • • Copper
  • • Brass
  • • Aluminum
Nickel-Gold Plating Advantages

ENIG plating comes with many advantages because there’s a uniform plating deposit, and it’s reliable for soldering and bonding. It also gives complete coverage for complex geometries compared to traditional electrolytic plating.
