摘要

Printed Circuit Boards are composed of multi-layered copper(CU) plate and glass epoxy. Each copper layer has the complicated and different pattern to correctly operate for its mission. In that case, PCB(Printed Circuit Board) stiffness are affected by the copper layers. By reasoning of this complicated copper layer pattern, it is difficult to determine the PCB stiffness. Solar array regulator for KOMPSAT(Korea Multi Purpose SATellite) has two type of PCB. In this study, the methodology of calculation of the PCB stiffness for KOMPSAT SAR unit is suggested considering the concept of simplified representative volume element and It will be correlated with the results under KOMPSAT vibration test condition.
