Choosing the right surface finish for a PCB is essential for achieving peak performance, and San Francisco Circuits understands this well. discover more >>
One of the most popular surface finishes is Electroless Nickel Immersion Gold (ENIG), known for its excellent corrosion resistance and alignment with lead-free manufacturing standards. Its flat surface is particularly favorable for assembling complex and densely packed PCBs.
At San Francisco Circuits, a diverse selection of surface finishes is available, all adhering to RoHS and WEEE regulations and ensuring they are lead-free.
The ENIG process involves applying a gold layer over nickel through a chemical reaction, resulting in a gold thickness of 2-5μ inches atop 120-240μ inches of electroless nickel. This dual-layer technique not only boosts durability but also preserves a smooth finish.
ENIG is particularly suited for applications that demand longevity and a flat surface, making it ideal for high-density and flexible pcbs. Its usage spans multiple sectors, including consumer electronics, telecommunications, aerospace, military, and healthcare devices.
