Direct Thermal Path MCPCB

Thermal conductivity Max.  385 W/m.k

What is direct thermal path metal core PCBs?

LEDs Chip Thermal Pads solder to the Aluminum or Copper substrate directly,
No dielectric between LEDs heat out pads and the Metal core.
Means,thermal resistance is very small and,
Thermal conductivity could be 175 W/m.k ( direct to aluminum) to 385 W/m.k( direct to copper ).

The regular MCPCB is 1.0 w/m.k
