Predictive Modeling of the Dynamic Response of Electronic Systems to Shocks and Vibrations

Abstract

The published work on analytical (“mathematical”) and computer-aided, primarily finite-element-analysis based, predictive modeling of the dynamic response of electronic systems to shocks and vibrations is reviewed. Understanding the physics and the ability to predict the response of an electronic structure to dynamic loading has been always of significant importance in military, avionic, aeronautic, automotive, and maritime electronics. For the past decade, this problem has become important also in commercial, and, particularly, in portable, electronics in connection with accelerated testing on the board level of various surface-mount technology systems. The emphasis of this review is on the nonlinear behavior of flexible printed circuit boards experiencing shock loading applied to their support contours.
