Cu Wire

  • Cost saving alternative of Au wire
    20 years of challenge of Cu wire technologies for the applications of greater sophistication and complication and the global market.
    Well prevailed cost saving material globally with gold price rising of recent years as a background.
    Widely adopted by discrete package to IC package with high number wires.

High-Purity Copper Type
TC-A Series

  • Copper has a lower cost than gold.

    Copper wire offers superior long-term reliability compared to gold wire. It is suitable for automotive ICs.

    Copper wire's electroconductivity is superior to that of gold wire. Copper wire exhibits good heat release and is ideal for use in high-speed ICs.

    The initial ball is soft and the use of high-purity (6N) copper as a source contributes to damage-resistant chips.

    Excellent second and subsequent bonding results from the oxygen-free (4N) copper characteristic.

 

Oxygen-Free Copper Type
TC-E Series

  • This material is lower-cost than high-purity (6N) copper for superior cost effectiveness.
  • The squashed ball shape offers superior wire strength and circularity compared to high-purity (6N) copper.
  • Offers long-term reliability superior to that of gold wire. It is suitable for use in automotive ICs.
  • Offers superior electroconductivity compared to gold wire.
    Copper wire exhibits good heat release and is ideal for use in high-speed ICs.
