What is Aluminum PCB?
Aluminum PCB is the PCB type that used the low alloyed Al-Mg-Si with high plasticity alloy plate as the substrate material that has better thermal conductivity, electrical insulation, and machining performance, compared with the traditional FR4 PCB.
Similar to other types of PCBs, Aluminum PCB is structured by the conductive layer (copper layer); insulation layer (dielectric layer); and the substrate layer.
Aluminum PCB is capable to stand higher current with the same thickness and line width. Aluminum PCB is able to withstand voltage up to 4500V and thermal conductivity is more than 2.0. At present, aluminum PCB is the most common type for LED lighting PCB applications.
Common LED PCB has two sides. The top side with white solder mask is used for soldering SMD LED beads, and the other side normally has no solder mask and showing as aluminum metal color. If there is a demand for high-power heat dissipation, the aluminum base can also be coated with a thermal conductive silicone grease layer to connect with the installed heatsinks for better heat dissipation.
