2 Layer ENIG (Electroless Nickel Immersion Gold) PCB finish is a popular surface treatment for printed circuit boards. This finish consists of two layers: a thick layer of electroless nickel covered by a thin layer of immersion gold. The nickel layer provides corrosion resistance and serves as a diffusion barrier, while the gold layer offers excellent solderability and protects the nickel from oxidation.
ENIG is widely used in the electronics industry due to its flat surface, which is ideal for components with fine pitches. It offers good shelf life, uniform thickness, and is suitable for both through-hole and surface mount technologies. The 2-layer structure of ENIG provides a balance between performance and cost, making it a versatile choice for various PCB applications.
