We address some basic problems of the dynamic response of electronic systems to shocks and vibrations, with an emphasis on analytical (“mathematical”) modelling, reliability physics behind the addressed phenomena, and design-for-reliability (DfR) issues and challenges, including probabilistic DfR (PDfR). The problems addressed include, but are not limited to, the attributes of analytical modelling, linear response (effect of viscous damping, shock tests vs. drop tests, role of compliant interfaces, maximum acceleration as an adequate reliability criterion), nonlinear response of a printed circuit board (PCB) to an impact load applied to its support contour, random vibrations, and shock protection of portable electronics, including application of nano-wires as a suitable “cushion”. Basic concepts are illustrated by numerous practical examples. The seminar is intended for scientists and engineering students, as well as for engineers and engineering managers, who are interested or involved in the field of the dynamic response of micro-electronic, opto-electronic and/or photonic systems, and/or micro-electro-mechanical systems (MEMS) and MOEMS (optical MEMS ) to shocks and vibrations.
