Copper-based PCBs, built on highly thermally conductive pure copper or copper alloys, offer excellent thermal conductivity (up to 380W/mK), rapidly dissipating heat generated by high-density electronic components and significantly improving system stability. These boards are particularly well-suited for applications requiring demanding heat dissipation, such as high-power LEDs, laser devices, power conversion modules, and high-frequency communications equipment. Their metal substrate also provides electromagnetic shielding, reducing signal interference. Copper-based PCBs support fine-grained circuit processing and maintain excellent performance in high-temperature and high-humidity environments, making them the ultimate solution for addressing heat dissipation and reliability challenges in high-end power and automotive electronics.
