Do you know what is ENEPIG in PCB?
What is ENEPIG?ENEPIG-Electroless Nickel Electroless Palladium Immersion Gold is a surface finish for Printed Circuit Boards.ENEPIG works well with lead free and conventional eutectic solder alloys.This is the best way for gold wire bonding. Advantages for ENEPIG:

1.[Black Nickel" free – no possibility of grain boundary corrosion of nickel surface by immersion gold
2.Palladium acts as an additional barrier layer to further reduce copper diffusion to surface, thus ensuring good solderability
3.Palladium completely dissolves into solder, without leaving an excessively high P% rich interface, exposing an oxide-free nickel surface allowing reliable formation of Ni/Sn intermetallic
5.Withstands multiple lead-free reflow soldering cycles
6.Demonstrates excellent gold wire bondability

7.Process costs substantially lower than electrolytic nickel gold or electroless nickel electroless gold
