Two Layers Sink PAD PCB with 2OZ copper made by Best Technology
Sink PAD PCB Technology reduces LED junction temperature compare to conventional MCPCB, Aluminum PCB or FR4 PCB. The Heat Sink design completely eliminates the substance with the lowest thermal conductivity/highest thermal resistance from the system. Direct Thermal Path still uses a dielectric, but this dielectric insulates the metal base electrically and leaves it uninsulated thermally. This not only increases thermal conductivity but also directly reduces production costs. In the case of applications that already had inadequate thermal conduction rates and then came to require an active cooling system, the reliance on these active cooling systems can be greatly reduced, reducing the size of these systems or eliminating them altogether will also reduce production costs.
