Aluminum Pcb Vs Fr4. Aluminum pcb have three layer stack up and fr 4 stacks up depend on each application it can have 1 2 3 or even more later in three layer stack up of aluminum pcb the dielectric layer is most different from fr 4 pcb. Aluminum substrate is usually one side but fr4 can do double sides.
Thermally conductivity aluminum pcb has a great capability of thermal conductivity than fr4 which makes them play an important role in. Aluminum pcb have three layer stack up and fr 4 stacks up depend on each application it can have 1 2 3 or even more later in three layer stack up of aluminum pcb the dielectric layer is most different from fr 4 pcb. 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.
The only reason for using an aluminum pcb is to transfer the heat from the emitters to a heatsink.
For the pcb boards now in application to led headlight there are mainly four kind of materials fr4 pcb aluminum pcb copper pcb and ceramic pcb. Thermally conductivity aluminum pcb has a great capability of thermal conductivity than fr4 which makes them play an important role in. 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. Aluminum pcb has high heat management most reason is it have dielectric layer.
