Cu Wire

In recent years, Cu wire become the cost saving alternative of Au wire due to the rise of gold price. Since 1987, Tatsuta always challenge the development of Cu wire technology for complex and sophisticated application in global market. Tatsuta Cu wire widely adopted mainly in automotive application, from discrete packages to IC packages.

Ag Wire

In recent years, Ag wire rapidly expanding as IC and LED applications. Tatsuta Ag wire contributes to improve LED brightness and has great reputation in LED industry. Ag wire application is expected to spread in the near future.

Pd-Cu Wire

Pd-coated Cu wire have the characteristic of both Au and Cu wire. This wire delivers the lower cost than Au wire, and has better manufacturing control than bare Cu wire.

Cu Heavy wire

Recently Cu heavy wire began to be used in place of Al wire, because chip material is changing from Si to SiC or GaN for high performance. Tatsuta's heavy Cu wire shows high electrical conductivity and high cycle test performance.
