PCB Fabrication :Electroless Nickel / Electroless Palladium / Immersion Gold (ENEPIG)

 In PCB Manufacturing

A final finish, which was already introduced more than ten years ago, is now receiving renewed attention because of its suitability for both Pb-free soldering and wire bonding applications, namely Electroless Nickel / Electroless Palladium / Immersion Gold (ENEPIG). Brittle fracture on BGAs is also no issue with this combination of metallic layers.
