基于键合线等效电阻的IGBT模块老化失效研究
Study of IGBT Module Aging Failure Base on Bond Wire Equivalent Resistance
摘要
Abstract
Literature about the reliability of insulated gate bipolar transistor (IGBT) revealed that bond wire lift-off failure is one of the most dominant factors affecting the reliability of IGBT. This paper proposed a condition monitoring method of IGBT module based on bond-wire equivalent resistanceRJ. The theoretical analysis about the relationship between equivalent resistance of bond-wires and turn-off transient-waveform of IGBT was developed at first; and then the equation calculating equivalent resistance was established; finally, the relationship between bond-wire equivalent resistance and lift-off bond wires was analyzed qualitatively and quantitatively through experiments. It is concluded that bond-wire equivalent resistance RJ will increase with the increase of bond-wires lift-off, which validates the feasibility and correctness of the proposed method.关键词
