Gold and Gold Alloy Bonding Wires
More than 50 Years of Trust and Experience
Gold (Au) and gold alloy bonding wires with high performance continue to support the semiconductor industry. They boast chemical stability and excellent electrical conductivity not found in other metals. Through material development, we can achieve functions such as fine pitch and low loop while maintaining high purity.
