Detailed information
ENIG PCB Manufacturing
The best features of ENIGs its flat surface and excellent solderability. The Electroless Nickel is an auto-catalytic process that deposits Nickel on a Palladium catalyzed Copper surface. Immersion Gold is replacement chemistry. In other words, it attaches to the Nickel by replacing atoms of Nickel with atoms of Gold. The recommended Gold thickness is 2-4 µin. The purpose of the immersion Gold layer is to protect the Nickel surface and maintain its solderability.
