Abstract
This study demonstrates a method for predicting the vulnerable location and fatigue life of an SSD (solid state drive) mounted on a notebook computer in a drop environment. In order to construct the drop environment of a notebook computer, a jig with the same weight and structure as the actual computer was used. The SSD was fixed in the same location as it would be on a notebook computer, and a drop experiment was performed. A drop analysis was performed by developing a finite element model of the notebook computer with the SSD. Additionally, we analyzed the effects of secondary contact between the SSD and other components. The vulnerable location was determined using the stress analysis results from the solder ball of the SSD. Using the analysis results and the Coffin -Manson equation, the fatigue life of the SSD in a drop environment was predicted.
