Abstract

Closed-form solutions for the dynamic responses of the printed circuit board (PCB) subjected to half-sine support excitation and with damping have been derived for the PCB that is modeled as an Euler beam. The analytical solutions have been used to investigate the effects of frequency ratio, damping ratio and distortion of the excitation pulse. Responses of the PCB were found to decrease non-linearly with increasing damping ratio. They are also dominated by its fundamental mode while the higher modes tend to decay more rapidly.
