Process ENIG - Electroless Nickel Immersion Gold

ENIG is the industry standard for uniform mid-phos EN deposits with a topcoat of immersion gold. A unique, reduction-assisted immersion gold process deposit higher thickness “4 to 8 μin gold” in a single step, with no corrosive replacement reaction. EN is an autocatalytic process that deposits a nickel-phosphorus or nickel-boron alloy onto a solid surface via chemical reaction, without electricity. Its primary purpose is to enhance a product’s corrosion and wear properties; it also improves solderability and lubricity.
