I need to control 60A of current on a PCB so can't really see any option but nice thick copper like 4-6 oz. I'll probably use 4 layer so that signals can get in and out more easily.
I am aware that thick copper creates problems for track width as at aome point you etch down this traces. But do i need to care ? thin traces are just for signals so if they end up thinner that does not matter, or are there manufacturing issues with an inconsistent thickness. Would the inner layers be less than 6oz and say just 1 oz ? What is the standard way of doing it ?
