Immersion Gold PCB

Immersion Gold,also called ENIG, has been growing as one of the best finishing methods for printed circuit boards. ENIG
is a costlier finish, but offers the best characteristics for pcbs.

Immersion gold chemistries offer many strengths like excellent surface planarity (particularly helpful for PCB's with large BGA
packages) coplanarity, excellent wettability, long shelf-life and surface oxidation.

ENIG doesn't require frequent dummy plating, excellent re-flow cycles, and gives level plating around the shoulders of pads and
circuits. Immersiong gold finish also provides both good adhesion as well as providing outstanding electrical testability

Compared with flash gold Immersion gold finish is cheaper because the thickness of gold. However, with good solderability.
