Affinity electroless nickel immersion gold (ENIG) final finish is for printed circuit board fabrication. Reportedly provides excellent performance in start-and-stop operation. Delivers stability in phosphorus content; eliminates startup dummy requirements, and operates under a range of bath loading. Has built-in protection against black line nickel. Includes pretreatment chemicals for removal of solder mask residues. Activation eliminates deposition in non-plated through-holes.
