摘要：

According to the problems of the vibration reliability of pcb in practical, a finite element model was established according to PCB actual parameters, and their first 4-order natural frequencies and modal modes are obtained by modal analysis, and the finite element model which is also helpful for the structural improvement is proved to be correct through the experimental modal analysis. And based on these, optimized design of PCB structure is accomplished for increasing the lower rank natural frequencies of pcb and enhancing the ability of anti-vibration and shock of pcb.
