The LED PCB comes into being with the rapid development of the printed circuit PCB industry. Some LEDs were soldered on PCB to created lighting electronic products.
As we all know that LED will generate more heat compared with other electronic parts, which required the PCB to have a better ability for dissipating heat. For these special requirements, metal core PCB are frequently used on LED PCB, especially aluminum core PCB. This is because 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.
