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. Jeffrey A.
