Engineering:Electroless nickel immersion gold
ENIG and ENEPIG are meant to replace the more conventional coatings of solder, such as hot air solder leveling (HASL). While more expensive and require more processing steps, they have several advantages, including excellent surface planarity (important for ball grid array component mounting), good oxidation resistance, and suitability for movable contacts such as membrane switches and plug …

PCB Surface Finish Types and Comparison
 · ENEPIG Electroless Nickel Electroless Palladium Immersion Gold, or ENEPIG, is beginning to be used more and more as a PCB surface finish. Compared with ENIG, ENEPIG has an extra layer of palladium between nickel and gold which further protects the nickel layer from corrosion, preventing black pad that may occur with the ENIG finish.

Microelectronics – An introduction
Electronics is a general term for the field of science that involves managing electric currents through circuits. Microelectronics is one of the sub-categories of electronics. Microelectronics specifically relates to manufacture of very small electronic circuits. It also incorporates the study and engineering of the circuits. Fundamentally, the term ‘micro’ relates to the measurement scale
