Taiwan's high-tech industry due to global environmental change and the whole industry into the era of highly competitive and profit of, for the sake of business continuity, will continue to use existing strengths to provide the semiconductor industry better alloy wire, to cope with the grim reality of the production costs challenges and expectations of the staff combined with the centripetal force ...
"Alloy Wire" is mainly composed of different metal composition, physical properties, fracture load, elongation at break, after the wire tension and thrust are better than gold wire, electrical conductivity and fusing current, thermal conductivity can be comparable to gold wire, but the price is significantly lower in gold thread.
Complete specifications alloy wire produced by our company, diameter 2.0 ~ 0.6mil (0.0500-0.0150mm), and can be tailored for client models, has a strong R & D team and production lines and deep technical foundation for backing, you absolutely can meet the needs of production quality and price.
