Heavy Copper PCB

Heavy Copper PCBs adopt thick copper foil with outstanding high-current capacity and excellent thermal dissipation. They are mainly used for high-power power modules, inverters, EV chargers, energy storage equipment and industrial drivers. Capable of carrying large current, reducing trace temperature rise and enhancing long-term operational stability.
