SinkPad PCB, also called Heat Sink or DTP (direct thermal path) PCB, it is a type of Copper base PCB used in thermoelectric separation application. It generally used for high power LED, the pad of LED touch the copper base directly, so that the heat generated by LED will dissipate quickly, which can achieve the best heat dissipation and conduction.
Thermoelectric separation technology is based on the higher heat dissipation requirements of high power electronic products, which needs to meet two basic conditions:
1.LED pad touches the base substrate directly.
It means we need to increase the path of the LED pad to the base substrate to accelerate the heat emission from the base material.
2.Higher heat dissipation substrate materials
Copper has a thermal conductivity of 401W/m·K, while aluminum has a thermal conductivity of 237W/m·K. Obviously, copper has better thermal conductivity because of its high density, high mass. Therefore, a SinkPad PCB usually means a SinkPad copper base PCB.
