I’ve been looking at designing a board that may need to use 2oz/70um copper for current-carrying capacity.
I have seen mentioned that when using 2oz copper, your minimum trace width and spacing must be larger compared to regular 1oz. Why is this?
And if so, what value would people recommend for minimum trace/space for 2oz? I usually go with 12 mil width and 10 mil clearance. Should I increase either?
