Linear Simplification of Dynamic Model for Printed Circuit Boards

摘要

Printed circuit board as the carrier of electronic components, the vibration characteristic of printed circuit board is related to the performance of the whole electronic equipment and the stability of the system. The printed circuit board material has non-linear characteristics, and because in engineering applications to solve the nonlinear vibration problem is very complex, and there is no suitable software to calculate. Therefore, this paper focuses on how to linearize the nonlinear vibration dynamic model of printed circuit board. In addition, the effect of concentrated mass on printed circuit board is studied by means of experimental modal analysis, which provides a simple and convenient method for studying the vibration characteristics of printed circuit boards. Circuit board on the reliability of components provided an important basis.
