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:
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.
