200℃ Polyester Amide Imide Enamelled Copper Wire For Generators

200℃ Polyester Amide Imide Enamelled Copper Wire For Generators

Copper bonding wires are currently the industry choice as an alternative to gold wires.Copper has high electrical conductivity when compared to gold (or aluminum). As a result better heat dissipation and increased power ratings are attainable with thinner wire diameters. Copper possesses higher mechanical properties compared to gold, enabling excellent ball neck strength and high loop stability. They are strong, with high tensile strength. Copper wires are used for both ball and wedge bonding when using a protective forming gas. Copper has good intermetallic stability which contributes, over time, to the bond reliability.Alongside the many benefits of copper wires, the inherent characteristics of the material also create many challenges semiconductor manufacturers struggle with when handling copper micro wires.

RUIYUAN was established in 2002, located in Tianjin City,the second largest port city in China.We have been focusing on different kinds of high quality wires: enameled round copper wire, rectangular enameled copper triple insulated wire, silk covered Litz wire, bonding wire and special enameled wire for 23 years.Ruiyuan is one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience. In 2019, our finest diameter is 0.011mm, and mass production has been achieved. All of our products are UL, RoHS certified, in line with industry standards IEC60317, JIS C 3202, NEMA, NW82.
