This is theoretically possible... We have a design we are reviewing prior to
testing that will carry 40-50 amps continuos. We achieved this by creating
extremely wide traces and selectively plating them to 0.030 thick (much
thicker then even 3 ounce copper). You might try contacting Speedy Metro
(sp?) for information on the selective plating design.
