Abstract :
This paper presents multi-scale analysis for a MEMS package system with experimental verifications to investigate dynamic responses under drop-shock tests. Dynamic responses such as acceleration waves of MEMS package in macro-scale are measured as the inputs of MEMS structures in micro-scale for numerical simulations. Structural deformation and stress distribution data are extracted and predicted. Possible applications include device fracture and in-operation stiction predictions for micro mechanical components in various MEMS sensors, including accelerometers and gyroscopes. We present results with MEMS accelerometers inside QFN packages.
