The thermal conductivity and dissipation is better than the other metal substrates. However, many factory put only one side on the PCB. The PCB boards which is made for copper Substrates has wonderful heat conductivity, electrical insulation and mach inability; moreover, it can strengthen the LED products and solve the problem of heat dissipation。
The features of Aluminum Substrates
1.SMT (Surface Mount Technology ) or COB (Chip on Board) 。
2.Improve the problem of heat proliferation in LED products。
3.Cool down the manufactures so quickly that improve the efficiency and life of products 。
4.Reduce the volume, additional features and costs 。
5.Surface treatment, polished and reflections 。
6.Replace the friable ceramics, own better mechanical durability。

Metal core PCB used for high voltage/high current、high temperature products, how to choose the MCPCB？
1. Certification：The raw material must have UL certification.(The list is as follows）。
2. Thermal conductivity………Important indicator
3. Breakdown Voltage………Important indicator
4. The characteristic of the metal base material
When it comes to LED product design, MCPCB play an important part in LED performance. K.T.Perfect provide different level of metal core PCB for different LED product,The purpose is to conduct the heat from LED to thermal module ASAP, keep LED live longer.
