Material stiffness of PCB
Material stiffness of PCB
(OP)
What is the Youngs modulus of a PCB. I have always assumed the the PCB is made from several layers 0/90 oriented layers of Continious Glass Fibre Plastic, and that no layers are oriented in 45 deg or any other directions. I need this to verify natural frequency of the PCB.
Thanks in advance

I use a value of about 3E10 Pa
Caution: the resonant frequency is strongly dependant on the constraints, e.g. sliding vs fix edges

What I am really asking is: Does the PCB have twisting stiffness of any significance?
