What a SinkPAD Board is?
A SinkPAD Board (SinkPAD PCB) is a special type of metal core PCB, the thermal conductive PAD is convexity area of copper core/pedestal, so that the thermal PAD of LED can touch the convexity area of metal core directly, and then the heat of LED will be dissipated into the air much faster and more efficient than conventional MCPCB, so that you can get superior thermal performance for medium to high power LEDs, or even for other chips/components.
Copper is the most popular raw material used for SinkPAD metal core, as the thermal conductivity is 400W/m.K, so normally people also named it as “SinkPAD copper core board”, or “SinkPAD copper core PCB”. While the thermal conductivity of traditional Metal Core PCB is only 1-5W/m.K, as the value is limited to dielectronic layer between copper trace and metal core.
The SinkPad provides excellent heat transfer from the LED to the metal base plate/pedestal, while maintaining excellent electrical isolation. The base copper base gives the board substrate mechanical integrity, and distributes and transfers the heat to a heat sink, mounting surface or directly to the ambient air.
As the electronic trace layer was in sink area of copper core, so we named that type of board as “SinkPAD Board (SinkPAD PCB)”, and because in most of cases, the material of core is copper, so it also named as “SinkPAD copper core PCB”, or “SinkPAD copper board”.
Because the heating of LED is conducting directly into copper core, which is different from traditional thermal path, so it also named as DTP (Direct Thermal Path) MCPCB, “DTP board”, or “DTP PCB”.
The electronic related function was on trace layer and thermal conduction was on copper core, and they are separated from each other, so that layer also named as Thermoelectric separation circuit board.
