PCB designers please help!
We are designing 2 oz copper PCB with the plain which suppose to carry 30 amps.
1. How many vias would be necessary to transfer 30 amps from one side to
another?
2. Does the via need relief (wagon wheel) or may be solid?
3. What should be the via size (0.020" or 0.031")

Any input would be greatly appreciated.
Thank you,
Stella Neyman
