ENIG Plating

ENIG Plating

ENIG (Electroless Nickel Immersion Gold) is a widely used metal plating process in the manufacture of printed circuit boards (PCBs). This method deposits a thin layer of electroless nickel followed by a layer of immersion gold, providing a highly reliable, corrosion-resistant finish. The resulting finish is ideal for enhancing the performance and longevity of PCB contacts.

ENIG plating offers superior surface planarity, making it a top choice for PCBs with fine-pitch components. It's also fully compatible with lead-free soldering processes, making it an excellent option for industries that adhere to environmental regulations. Additionally, ENIG plating ensures outstanding solderability and is wire bondable, which is essential for high-performance, long-lasting electronic connections.
