Benefits and Advantages
The use of heavy copper PCBs provides several significant benefits:
High Current Carrying Capacity: This is the most notable advantage. The thicker copper traces can handle substantially higher currents—from 10 to hundreds of amperes—compared to standard PCBs, preventing trace burnout and electrical failures.
Superior Thermal Management: Copper is an excellent thermal conductor. The thicker copper layers effectively spread and dissipate heat away from critical components, reducing the risk of overheating and extending the lifespan of the electronic device.
Enhanced Mechanical Strength: The robust copper structure provides greater durability and resistance to thermal stress, vibration, and physical shock. This makes heavy copper PCBs ideal for use in harsh environments.
Integration of Power and Control Circuits: Heavy copper plating technology allows for the integration of high-current power circuits and low-current control circuits on the same board, simplifying the design, reducing the overall size, and potentially lowering costs.
Reduced Product Size: By using thicker copper, designers can achieve the required current-carrying capacity with narrower traces, which can help to reduce the overall size and layer count of the PCB.
