Heavy copper high power circuits.
* Our multiple levels allow one layer to have 8 oz. of copper for the heavy tracks, and 1 oz. of fine-featured traces for SMT circuitry, all interconnected and intertwined.
* A two-ounce circuit's maximum current is about 25 amps; a 1"-wide 15 oz. trace can carry 200 amps at only 30[degrees]C rise.
* While copper thickness can be varied by layer, line/space requirements are 3 mils per oz. The heavy copper can be any thickness as a base copper from 1/2 oz. to 12 oz. The thicker the base copper compared to the final copper thickness means less to plate and less expense.
