Metal Core PCB
Metal Core PCB is the metal core object for PCBs.
It is infused from a technology developed to overcome the thermal limitations.
Most of these PCBs are made of Aluminum core, copper core, and Steel Alloy.
Metal core PCB is ideal for its applications that generate immense heat and have difficulty being cool down using conventional fans or other cooling methods.
MCPCBs play an integral role to achieve a high illumination with fewer requirements than LEDs require.
The fabrication process of metal core PCB is helpful for the applications
Since the MCPCBs are most often used in LED technologies for producing and high power electrical source.

Advantage of metal core PCB
1 . High thermal conductivity
General Aluminum core PCB
could be 0.8/1.0/1.5/ 2.0 w/m.k up to 12 W/m.k
Special technical Aluminum PCB
could 173 w/m.k (direct chip on Aluminum)
Special technical Copper Substrate PCB
could be 384 w/m.k (direct chip on copper)
FR4 is approx only 0.3 W/m.K
2. Dimensional stability
It is clear that the size of the metal-based printed circuit board
more stable than insulating materials.
The size change of 2.5 ~ 3.0% when Aluminum PCB and
aluminum sandwich panels was heated from 30 ℃ to 140 ~ 150 ℃.
