San Francisco Circuits knows that selecting the appropriate surface finish for a PCB is critical to ensuring optimal performance. Read more >>
Electroless Nickel Immersion Gold or ENIG has become a favored surface finish thanks to its strong resistance to corrosion and compatibility with lead-free standards. It also provides a flat surface, making it well-suited for assembling intricate and high-density PCBs.
San Francisco Circuits offers a wide range of surface finishes, all of which are lead-free and compliant with RoHS and WEEE regulations.
The ENIG surface finish applies a layer of gold over nickel through a chemical process, with 2-5μ inches of gold deposited over 120-240μ inches of electroless nickel. This double-layered approach enhances durability while maintaining a smooth surface.
ENIG is especially recommended for applications requiring a long shelf life and flatness, such as high-density and flexible PCBs. It is widely used across various industries, including consumer electronics, telecommunications, aerospace, military, and medical devices.
