SinkPAD PCB is a special type of metal core PCB( MCPCB ),
The LED sink heat pad solder direct to the metal substrate,
Also,it is called Thermal pad MCPCB,direct thermal path mcpcb.
There are 2 types metal substrate,
Aluminum core sinkpad PCB and copper core sinkpad PCB.
Aluminum core sinkpad PCB thermal conductivity could be 235 W/m.k,
Copper core sinkpad PCB thermal conductivity could be 385 W/m.k
LEDs Chip Thermal Pads solder direct 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 235 W/m.k to 400 W/m.k.
Aluminum core sinkpad PCB stack up
Copper substrate sinkpad PCB stack up
Metal core PCB’s thermal conductivity only 1.0 W/m.k, maximum 12 W/m.k.
Sinkpad PCB thermal conductivity is much better than metal core PCB.
The SinkPad PCB provides fine heat transfer from the LED to the metal substrate,
