[393] Effect of Static Strength on High Cycle Fatigue Life of Sn-Ag-Cu Solder Joints

*Daigo YAMAZAKI1, Yoshiharu KARIYA2, Ryota KAMEKURA1 (1. Graduate School of Shibaura Institute of Technology, 2. Department of Materials Science and Engineering, Shibaura Institute of Technology)

Keywords:High cycle fatigue、Solder joint、Microstructual coarsening、Vibration load、Static strength

Sn-Ag-Cuはんだ接合部の高サイクル疲労寿命におよぼす静的強度の影響を実験および有限要素法解析から精査した.長期使用中のはんだ接合部の疲労寿命は短くなり,Basquin則は降伏応力に依存することが示唆された.
