Semiconductor
Probe pins used in semiconductor inspection and micro-scale testing face extreme operational demands, including millions of contact cycles, high frequencies, and exposure to oxidation. Conventional plating techniques struggle to balance contact resistance, mechanical hardness, and uniform thickness across ultra-fine pin geometries. Poor plating consistency leads to unstable signal transmission, premature contact tip wear, pin deformation, and frequent equipment downtime during high-throughput semiconductor testing.
Our Competitive Advantages & Key Differentiators:
・Mitsuya provides ultra-high-precision plating solutions tailored specifically for next-generation probe pin applications, delivering unmatched signal reliability, wear resistance, and operational lifespan.
・Diverse Precious Metal Coatings: We offer specialized deposits matched to your exact testing environment:
・Rhodium (Rh): Extremely hard surface for extreme wear resistance and extended pin operational lifespan in high-cycle testing.
・Palladium (Pd): Balanced conductivity and wear/oxidation resistance as a cost-effective alternative to gold.
・Gold-Tin (AuSn): Exceptional thermal performance and high mechanical strength for solderable probing interfaces.
・Gold (Au): High electrical conductivity and corrosion resistance for low-signal, high-precision applications.
・Precision Engineering & Uniformity: Micro-thickness controls guarantee consistent coating thickness across complex pin geometries, maintaining stable electrical contact even in high-frequency and micro-scale testing.
・Fully Customizable Multi-Layer Solutions: We provide bespoke plating configurations (e.g., Ni + Au, Pd alloy underlayers), thickness optimizations, and application-specific material selection through a seamless one-stop process.
