Pcb pad thermal resistance
SpletThermal Resistance in PCB Heat management plays a crucial role in keeping components cool during operation. Arguably, FR4 is the commonest substrate material. However, it … Spletthe parts are reflowed onto ceramic substrates which are then screwed down to reliability boards using thermal grease. For 3-pad devices which have two electrical contacts and a thermal pad (such as LUXEON Z ES), the contact pads are soldered to the ceramic substrates. For the very conductive TIM measurement, the thermal pad is also soldered.
