Preliminary Design for the Vibration Analysis of a PCB Model—An Analytical Approach

Printed circuit boards (PCBs) are essential modules which are incorporated in a wide range of industrial equipment in order to control or signal manipulation applications. Printed circuit boards are subjected to various types of loads, such as vibrations, shocks and static loads. This paper discusses the development and use of an analytical approach for predicting the dynamic response of a flexible printed circuit board (PCB) at an early stage of design. The main contribution of this research work is to reduce the designing time and to increase efficiency, computer simulation (modeling) commonly used. As an application, the dynamic response of a simply supported circuit board, during the drop test, to an impact load applied to its support contours is presented and discussed using the modeling software tool Modelica/Dymola. An overview of the desired system behavior can be performed and the effects of some parameters on the system response can be analyzed. The model can be helpful in the analysis and the design of PCB structures experiencing dynamic loading in the preliminary vibrational design. For validation purpose, the obtained results are compared with those reported in the literature.
