Jaka jest najlepsza praktyka dotycząca PCB w zakresie termicznego umieszczania urządzeń półprzewodnikowych SMT?

Thermal via’s don’t work well to conduct heat because they are essentially a copper-lined hole. If you really want to conduct heat to another layer, then you should really think about using through-hole components.

Copper pads do conduct heat well

1. When we use the ‘copper pour’ function of your layout software to fill everything else with as much copper ground plane.
2. When we oversize heat generating traces* to wick the heat away from the hot component

* where signal frequency is low enough to not be a consideration
