Metal Core PCB (MCPCB): Adopting high-quality metal substrates (aluminum, copper, or iron) with excellent thermal conductivity, heat dissipation efficiency far superior to traditional PCBs. It is mainly applied to high-power electronic products such as LED lighting, power modules, automotive headlights, industrial power supplies and LED displays. The metal base effectively dissipates heat generated by electronic components, solves the problem of heat accumulation, greatly extends product service life, improves operational stability, and reduces failure rates, making it the ideal choice for high-power, high-temperature working scenarios.
