Heat management for high-power LEDs is also an issue. Our team uses heat-dissipating metal core PCBs (MCPCBs) to address this problem.
We source our metal-core substrates from companies such as Thermagon, Bergquist, Arlon, and Univaco. These products help dissipate the excess heat from LEDs.
However, these materials occasionally make transferring heat from the prepreg to the metal core difficult.
