If you keep the traces on a surface layer you'll benefit from improved thermal
dissipation and increased conductive thickness from the surface plating. Using
typical 20 deg C rise max and 1oz copper with 1 oz plating and adjacent plane
10 mils away, I get 32A with Saturn Toolkit

Hi
Try the free tool from Saturn pcb... It's very great and can compute the trace
width vs copper weight and Max temp. Rise you want to accept...
It does the job for both external and internal trace as well for the VIA
I hope it helps

hi Experts,
I need some guidance on how to calculate the trace width for High
Voltage AC line (80-240V) in PCB and maximum current shall go to 30A.
If I use conventional Trace width calculators available in web, it
calculates to very large trace widths 645mills in external layers and
248mills in internal layers with 2oz copper thickness.
Thanks in Advance
Harini
