Applications of Copper-Base PCBs
Copper base PCBs are used for high-power applications, applications in areas with large temperature differences, and heat dissipation for precision communication equipment. And some applications of copper-base PCBs are:

LED lights: copper-base PCBs can be used for LED lights, especially COB LED lights. COB LEDs can be bonded to the LED plates by gold wires or solder balls from PCBONLINE, and then the LED module is surface-mounted on the copper-base PCB to make the LED lights.
Automotive lighting: double component-mounting-sided copper-base PCBs can be used for the headlight of vehicles. The double-sided copper-base PCB provides high efficiency, excellent heat dissipation, and a superior spotlight effect. Both regular copper-base PCBs and thermoelectric separation PCBs can serve automotive lights.
Charging piles for electric vehicles: copper-base PCBs can be used for the charging piles for EVs and HEVs. For example, the adaptor board in the high-power charging pile is a copper/FR4 hybrid PCB. For reliability and safety, in the PCB design, large-current circuits and small-current circuits are separated. The copper plate areas conduct large currents and dissipate heat, and the FR4 areas conduct small currents and signals.
Conclusion
Copper-based PCBs have good thermal conductivity and are used for high-power devices and systems. There are regular copper-base PCBs with 1W/mK to 9W/mK thermal conductivity, and thermoelectric separation copper-base PCBs with 398W/mK thermal conductivity.
