SpletTrack Current (IPC-2152) Calculator Intermediate Variables This calculator can find the minimum allowed PCB track width for a given continuous current. Takes into account the allowed temperature rise, copper track thickness, proximity to planes, total thickness of the PCB, and PCB material in accordance with IPC-2152. SpletBy the way, it may seem counterintuitive, but thicker conductors have lower current carrying capacity than thinner ones because of the smaller trace width at a given A C . For those who work with metric units, here is a quick conversion reference for copper trace: 1 mm=0.03937", 1 mil^2=0.000645 mm^2, 1 oz/ft^2 copper is 0.033 mm thick minimum.
