The ENIG is a common acronym that stands for Electroless Nickel Immersion Gold. As the hot air solder leveling, it is also a surface finish of the printed circuit board industry. The ENIG got its name because it comprises electroless nickel plating, which is coated with a slim layer of immersion gold.

The ENIG process generally involves cleaning the bare Cu, etching, applying a catalyst, acid dipping, and electroless Ni and immersion Au deposition.

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.

The new nickel coating solution developed has properties that allow it to control the solution's stability and decrease the brittleness of the nickel layer to allow more flexibility. For ENIG finishes, the risk of black-pad problems poses a real threat to the operation of whatever ball grid array — or BGA — components or other items are attached to the PCB. Unfortunately, ENIG finishes can’t be re-worked, so the problem of black pad is a crucial one that needs to be addressed properly. ENEPIG is similar to ENIG in both utilize electro-less nickel on top of copper plating; the difference is while ENIG has gold deposited directly on top of nickel, ENEPIG has an additional layer of palladium between the nickel and final gold layer (see below Fig. 1). Mit Eniig European Patent Office Issues National Patents in UK and Germany for Hybrid Propellant Electromagnetic Gun System (EP 3084337) to ENIG for its HyGUN-2™-related Technology May 23, 2018 United States Patent Office announced today the issuance of Patent No. 9,784,523 (Application 15/106,360) entitled Hybrid Propellant Electromagnetic Gun System ENIG is RoHS compliant is therefore one of the most used PCB surface finishes even though it is more complex and expensive when compared to other PCB plating process like HASL. ENIG is a two-layer metallic coating – Nickle is the barrier to the copper pad and is also the materials to which the components are soldered.

ENIG Plating: Advantages and Disadvantages. ENIG plating is much softer than hard gold plating.

Now chemical immersion gold generally refers to ENIG (Electroless Nickel Immersion Gold). The advantage of ENIG plating is that it can attach "nickel" and "gold" to the copper without the complicated electroplating, and its surface is flatter than electroplated gold, which is good for the finer and finer pitch. ENIG can also be applied before solder mask. In that case it resides over the entire copper surfaces of the outer layers of the PCB and we call it, Che Ni/Au overall.
