Aluminum Pcb Vs Fr4. The only reason for using an aluminum pcb is to transfer the heat from the emitters to a heatsink. Thermally conductivity aluminum pcb has a great capability of thermal conductivity than fr4 which makes them play an important role in.
In the cost comparison the aluminum pcb is more expensive than fr4 as well as more superior in performance. Aluminum pcb has high heat management most reason is it have dielectric layer. Yes it is a cluster of 6 leds per board and it won t be directly exposed to the environment which is why aluminum is suitable.
As below picture aluminum pcb bottom layer is aluminum fr4 pcb bottom layer is copper aluminum dissipation is better than copper so aluminum pcb dissipation is dramatically superior to standard fr 4 constructions.
