Heavy copper PCB, defined as any board with copper thickness of 3oz (105μm) or greater on any layer, is engineered for high-power applications requiring exceptional current carrying capacity and superior thermal management. With outer layer copper weights ranging from 3oz to 20oz (105μm to 700μm) and inner layers stackable up to 200oz, these boards support currents exceeding 100A while maintaining low electrical resistance and efficient heat dissipation. The robust copper construction minimizes voltage drops, reduces resistive losses, and provides effective heat spreading, making heavy copper PCBs the preferred solution for power supplies, motor drives, welding equipment, and electric vehicle charging systems.
High current-carrying capacity and low electrical resistance ensure efficient power delivery for AC-DC converters, DC-DC modules, and uninterruptible power supplies (UPS). The heavy copper construction handles elevated currents with minimal temperature rise, extending component life.
Robust copper traces withstand the high inrush currents and continuous loads of motor control applications. The enhanced thermal dissipation keeps power semiconductors within safe operating temperatures during extended operation.
EV charging stations and onboard battery management systems leverage heavy copper PCBs for high-current power distribution. The 100A+ capability supports fast charging requirements while maintaining reliability under continuous duty cycles.
