Printed Circuit Board Surface Finishes Advantages and

Electroless Nickel Immersion Gold (ENIG) ENIG is a two layer metallic coating of 2 8 μin Au over 120 240 μin Ni. The Nickel is the barrier to the copper and is the surface to which the components are actually soldered to. The gold protects the nickel during storage and also provides the low contact resistance required for the thin gold deposits.
