Abstract
In this paper, the characteristics of the Ag sinter bonding of the Si power module are described, and the effect of the change in creep properties due to sintering condition on the Ag sinter bonding layer was investigated. The authors have been studying changes in creep properties and fatigue life of Ag sinter materials. The Manson-coffin rule is derived using TCT analysis. Calculate the temperature change at the bonding layer using electro-thermal analysis. Based on the result, PCT analysis are performed. the Inelastic strain range of the bonding layer is investigated by thermo-structural analysis. Based on the results, the fatigue strength properties of the Ag sintering bonding layer are investigated using the Manson-coffin rule. It was found that creep has a significant effect on fatigue life.
