Aluminum Core PCB possess the ability to integrate a dielectric polymer layer with high thermal conductivity for lower thermal resistance. Too much heat accumulates in the Aluminum based PCB, which eventually leads to mechanical equipment malfunctions. Electronic devices that generate a considerable amount of heat cannot always be cooled using conventional fans. Conductive cooling through Aluminum clad PCB is an ideal option. In conductive cooling, the heat is transferred from one hot part to a cooler part by direct contact. This works well since heat constantly seeks to move to any object or medium that is cooler.
Metal substrates are long-lasting and are more conductive than epoxy products. The higher the conductivity of the metal, the faster the heat transfer.
