PARTICLE IMPACT DAMPERS MITIGATE RANDOM VIBRATION FATIGUE IN PRINTED CIRCUIT BOARDS

摘要

This paper describes how Particle Impact Damping (PID), has been successfully applied to attenuate random vibration response in Printed Circuit Boards (PCB). Particle damping is a simple, compact and low cost solution with several inherent advantages over traditional mitigation methods. This paper is intended to inform the PCB design community of best-practices and design principles to prevent severe vibrations that damage circuit cards. By applying an effective PID design solution, PCB life and reliability can be significantly improved.
