I need to know when we are mapping copper trace on pcb , why pcb total mass is not changed? It is still showing mass of pcb equivalent to dielectric material used. I tried on several multiplayer PCBs and getting first natural frequency close to actual vibration test done on vibration shaker but higher modes are showing large error why so??

If copper trace is mapped over pcb then model mass should change, why it is not reflected?

Waiting for your reply.
