Description

Recently, the underfill mount structure is noticed. However, the sufficient thermal fatigue reliability evaluation has not been established. In this study, the authors proposed a simple reliability evaluation method using Finite Element Analysis (FEA) . In addition, an approximate calculating method for the reliability evaluation parameter (Total equivalent inelastic strain range) was developed using Statistical Design Support System (SDSS) .
