提升成本管理的金线替代品

Silver (Ag) alloy and Copper, Palladium Coated Copper (PCC) wires have emerged as alternatives to gold bond wires. Silver alloy offers properties like those of gold with a cost similar to PCC. Copper wire offers a significant cost advantage over gold and is an excellent replacement due to similar electrical properties.

银合金焊线的重要
特性和优点

  • 银线比 PCC 更加柔软,从而减少铝溅出并降低焊盘损坏的风险
  • 银线具有更大的制程窗口,能够提升焊盘结构脆弱设备的工艺性
  • A low-cost replacement for applications that need:
    • 晶粒之间焊接、多级焊接
    • 超小焊盘节距 (BPP) 和小焊盘开窗 (BPO)
    • 超低线弧高度

铜焊线的重要
特性和优点

  • 相较于金线具有明显的成本优势
  • 由于电气特性相似,是金线的理想替代品
  • 金线与铜线的自电感和自电容几乎相同
  • 更低电阻率
  • Where resistance due to the bond wire can negatively impact circuit performance, copper wire can offer improvement
