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
- When we use the ‘copper pour’ function of your layout software to fill everything else with as much copper ground plane.
- 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
