Enhancing Reliability with Advanced Surface Finishes: ENEPIG, Immersion Silver & More

2026-01-04 14:32

Surface finish selection significantly impacts solderability, shelf life, and end-use performance. BQ-Circuit offers a variety of high-quality finishes, including ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold), Immersion Silver, Selective Gold, and others. ENEPIG, for instance, provides excellent corrosion resistance and is suitable for gold wire bonding, while Immersion Silver offers a flat surface ideal for fine-pitch SMT assembly. Our technical team can recommend the optimal finish based on your assembly process, environmental requirements, and cost considerations.
