Solid-state drive 강제진동시 dummy solder ball 효과에 의한 피로수명 예측
Fatigue Life Estimation of Solid-state Drive due to the Effect of Dummy Solder Ball under Forced Vibration
- 발행 : 2014.10.29
초록
This research proposes a method to estimate the fatigue life of solid-state drive(SSD) due to the effect of dummy solder ball under forced vibration. Mechanical jig is developed to describe the SSD in laptop computer. The jig with SSD is mounted on a shaker, and excited by a sinusoidal sweep vibration within the narrow frequency band around the first resonant frequency until the SSD fails. A finite element model of SSD is also developed to simulate the forced vibration. It shows that the solder joints at the corners of controller package are most vulnerable components and that placing dummy solder balls at those area is effective method to increase fatigue life of SSD.
