Subject: [DC] Carrying current through a via
How would one calculate how big a via hole has to be in order to carry
enough current through it to meet the load requirements?
I have a 4 layer, 2 oz, .062 thick, board that needs to carry 3 amps
through a via, (via barrel platting of .001). I can not find any
information that will help calculate how big the hole needs to be to
accommodate this.
Any assistance would be greatly appreciated.
Thanks,
Colleen
