Every PCB generates heat when current flows through its traces. At low current levels—tens or hundreds of milliamps—the heat is negligible, dissipated quickly by the surrounding material, and rarely a concern. But when current climbs into the amper...

When your PCB design needs to handle tens or hundreds of amps, ordinary copper traces quickly reach their limits. Standard PCB fabrication processes were designed for signals, not power. The copper weight, trace width, and thermal management techni...
