摘要: 由于铝线键合逐渐不能满足如今功率模块功率密度、工作温度不断提升的可靠性要求,因此采用铜线代替铝线,以实现更高的可靠性工作寿命。对比分析了铜线、铝线键合工艺的特点、结合强度和可靠性,证明了铜线键合工艺的可行性和高可靠性。同时分析了铜线键合工艺目前存在的问题和应对措施。

Abstract: As the Aluminum(Al) wire bonding can not meet the power density and working temperature rising reliability requirements of the power module, therefore, instead of Al wire with Cooper(Cu) wire, to achieve higher reliability life. The feasibility and high reliability of the Cu wire bonding are proved by comparing the characteristics, bond strength and reliability of bonding process of Cu wire and Al wire. At the same time, the existing problems and countermeasures of Cu wire bonding are analyzed.

Key words: Al wire bonding, Cu wire bonding, reliability
