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...

In power electronics PCB design, how you fill unused board area with copper matters more than most engineers realize. The choice between a solid copper pour and a hatched (crosshatch) copper pattern is not purely aesthetic—it directly impacts curre...
