FEA on PCB
FEA on PCB
(OP)
Hi All,
Does anybody know what are the appropriate material properties to use for PCB?
Our software gives the option of material type (isotropic, orthotropic, etc.), and I am sure PCB is not isotropic, but since we did not have all the data, we had to assume it as isotropic.
If somebody could advise on the reasonable assumption to use for PCB and where to find material properties (website or books?), I would appreciate it.
Thank you!

chose the most comon "FR-4"
Searched matweb for FR-4 and PCB and got this link

I hope this helps.

Apart from that, you might want to check to make sure the copper traces don't add any stiffness to the board.

Unless the components are physically large and massive such as transformers, modifying the bare pcb by adding mass is a reasonable approach and relatively easy to do.
Steinberg is very usefull.
