High Current PCB

is a specialized circuit board engineered to safely and efficiently handle substantial electrical loads, often exceeding tens of amperes. Unlike standard PCBs, it utilizes heavy copper layers (typically 2oz to 10oz or more) and wider traces to minimize electrical resistance and power loss. Effective thermal management is critical, achieved through strategies like thermal via arrays, copper pours, and high-performance substrates. These boards are indispensable in high-power applications such as industrial power supplies, motor drives, and automotive systems.
