An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means. Consequently, metal core PCBs are frequently chosen for LED application due to their enhanced ability to dissipate heat.
Aluminum in particular is often used to manufacture circuit boards for LED lights. The aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater
efficiency than a traditional rigid PCB.
