Product Description
8 Layer FR4 TG170 ENIG Electronic PCBA for Smart Home Main Board
What is ENIG PCBA?
ENIG PCBA refers to a printed-circuit board assembly where the bare board is finished with ENIG (Electroless Nickel Immersion Gold) surface treatment. This process applies a two-layer metallic coating:
- 3-6 µm of electroless nickel plating directly on copper pads, serving as a diffusion barrier and solderable surface
- 0.05-0.15 µm of immersion gold deposited on top of the nickel to prevent oxidation and maintain a flat, wire-bondable/solderable surface
Due to its exceptional planarity and corrosion resistance, ENIG PCBA is widely used in high-reliability applications including smartphones, aerospace systems, medical equipment, and telecommunications devices.
