Heavy Copper PCBs from San Francisco Circuits are engineered to support demanding electrical loads and enhanced thermal management in advanced unmanned platforms. Designed with substantially thicker copper layers than standard boards, these PCBs enable reliable handling of high current while reducing resistive losses and improving heat dissipation. This makes them well-suited for power distribution, motor control, and other energy-intensive subsystems within UAVs, UGVs, and autonomous maritime systems.
Manufactured with precision-controlled processes, heavy copper designs from San Francisco Circuits maintain tight tolerances while accommodating complex layouts and multilayer configurations. The increased copper weight enhances mechanical strength and durability, supporting operation in harsh environments where vibration, temperature variation, and continuous power cycling are present. These capabilities allow engineers to consolidate circuitry, improve system reliability, and optimize performance in space- and weight-constrained unmanned applications.
