A heavy copper PCB (Printed Circuit Board) is a type of circuit board that has significantly thicker copper thickness compared to standard PCBs.
This enhanced copper thickness is specifically designed to handle high-current applications and provide superior thermal management.
Copper Thickness: Standard PCBs typically have a copper thickness ranging from 0.5 to 3 ounces per square foot (oz/ft²), the heavy copper PCB is defined as having a copper thickness of 3 oz/ft² or more on its inner and/or outer layers. In some cases, "extreme heavy copper" PCBs can have copper weights exceeding 20oz/ft².

Applications
Heavy copper PCBs are essential for a wide range of high-power and high-reliability applications, including:
Power Electronics: Power supplies, inverters, and converters.
Automotive and Electric Vehicles (EVs): Battery management systems (BMS), motor controllers, and charging systems.
Renewable Energy: Solar power inverters and wind turbine controllers.
Industrial Equipment: Motor drives, welding machines, and robotics.
Military and Aerospace: Radar systems, power distribution units, and communication devices where reliability in extreme conditions is critical.
Planar Transformers: Heavy copper PCBs are used to create high-power-density planar transformers directly on the board.
