YIN GUAN offers a range of plating options based on product application and customer needs. Each process has its own strengths to enhance durability, conductivity, corrosion resistance, and appearance. All plating complies with RoHS regulations.
A dual-layer process with a nickel base and bright tin surface. The nickel provides hardness and corrosion resistance; the bright tin gives a silvery sheen and easy soldering. RoHS lead-free — widely used for jumpers, PINs, and terminals.
Nickel plating with high hardness, wear resistance, and corrosion resistance. Used as a standalone protective layer or as a base layer for gold plating. Applied to brush pins and precision parts for long-term use.
Gold plating with outstanding conductivity, oxidation resistance, and an attractive golden appearance. Used for high-end electronic contacts, premium brushes, and critical parts needing stable contact performance.
A dual-layer process with a nickel base and matte tin surface. The nickel provides hardness and corrosion resistance; the matte tin withstands SMT reflow high temperatures (260°C+) while reducing tin-whisker risk — an advanced choice for SMT lines.
A dual-layer process with copper inner layer and nickel surface. The copper provides conductivity and adhesion; the nickel provides hardness and corrosion resistance — the best balance of economy and performance.
A triple-layer process: copper inner, nickel middle, gold surface. Delivers the best overall performance — premium conductivity, excellent corrosion resistance, and attractive appearance. The top-tier surface treatment for high-end electronics.
