Metal Core PCB
How many advantage of MCPCB?
1 . High thermal conductivity
General Aluminum core PCB
could be 0.8/1.0/1.5/ 2.0 w/m.k up to 10 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 ℃.
