You need to strongly attach thermal pads with the ground planes of the motor driver PCB. Again, there should be a continuous copper plane between thermal pads and other portions of the PCB.
Motor Driver PCB Low Thermal Resistance
Regulating Copper Thickness
Copper thickness plays an essential role in promoting the thermal management of motor driver PCB. You can reduce the thermal resistance by using heavier copper on the PCB surface.
The following equation defines the relationship between copper thickness and the area of the PCB plane.
Thermal resistance,= ( length )/ area
So, these two are inversely proportional. You need to apply thicker copper on the PCB surface to ensure better heat conduction from the components. Usually, 1.5 Oz and 2 Oz copper render better service in this case.
Effective Thermal Vias
Thermal vias have an effective role in heat dissipation. They form a path between the top and ground layer of the PCB. you have to apply the via with proper hole size and diameter.
