基于殼溫的IGBT模塊鍵合引線疲勞壽命預(yù)測
[Abstract]:In order to study the fatigue life of bonding lead under power cycle and improve the reliability of IGBT module, a method for predicting the life of bonding lead based on shell temperature is proposed in this paper. The fatigue failure mechanism of the bonding lead is investigated by testing the power cycle of the IGBT module, and then the electric-thermal-structural strong coupling model of the IGBT module is established, and the electrical, thermal and structural characteristics of the module under the power cycle load are analyzed. According to the strain of bond lead and the fatigue curve measured by experiment, the fatigue life of bond lead is evaluated, and the prediction model of its life is established on the basis of shell temperature. The accuracy of the model is verified by comparing the test results. Finally, the improvement scheme of copper bonding lead is put forward. The failure rate of IGBT module can be reduced by determining the service life of bonding lead and changing the device in advance according to the easily measured shell temperature.
