I am trying to perform a modal and dynamic analysis on aprinted circuit board (PCB) and have found it difficult to obtainreliable material specifications. My initial Frequency analysisindicated displacements of several meters. Can anyone point me toreliable material specifications for the FR-4 (epoxy laminate)material and how to accurately model a 6 layer PCB with 2 1 oz.interior copper layers and .5 oz. outside copper layers?SolidworksSimulation
