Heavy Copper PCBs offer superior current carrying capacity, enhanced thermal management through better heat dissipation, increased mechanical strength at connector sites, and improved reliability in high-power applications.
These PCBs are essential in power electronics, automotive systems, industrial controls, power supplies, renewable energy systems, aerospace, and telecommunications equipment where high current and thermal management are critical.
Increased copper thickness (typically 3oz/ft² to 20oz/ft²) allows for higher current carrying capacity, reduces thermal resistance for better heat dissipation, enables wider trace spacing, and improves durability in demanding environments.
