FAQ:
Question: What is ENEPIG Plating?
Answer: ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) is a type of surface plating applied on a Printed Circuit Board to protect it from environmental factors during storage and operation. ENEPIG is prepared by depositing electroless Nickel (Ni 3-5 μm), followed by electroless Palladium (Pd 0.05-0.1μm), and an immersion Gold layer (Au 0.03-0.05 μm). It is good for solder joint strength, gold wire bonding, aluminum wire bonding, and provides low contact resistance. It can easily be deposited on almost any PCB which is why it is also called the ‘Universal Finish’.
What are the advantages of ENEPIG over ENIG?
ENEPIG plating has an additional layer of Palladium when compared to the ENIG plating which consist of just Nickel and Gold. This additional layer helps avoid what is know as the ‘Black Pad’ syndrome i.e. the result of corrosion caused by the Gold to the Nickel layer.
Advantages of ENEPIG Finishes:
Limitation of ENEPIG Surface Finish: It is more prone to fractures due to the brittleness of the tin-palladium layers formed on top of the nickel plating.
Uses of ENEPIG Surface Finishes
ENEPIG Surface Finishies are ideal for Printed Circuits Boards that support various package types including THT (through-hole technology), SMT, BGA, wire bonding, etc. They are often used in the aerospace & defense industry as well as the medical industry. ENEPIG finishes are used in high density, high performance devices.
