♦ What is Thick copper PCB?

Thick copper PCB refers to a circuit board formed by bonding a layer of copper foil with a thickness of 2 ounces (oz, about 62.5 microns) or more to FR-4 or other substrates during the printed circuit board (PCB) manufacturing process.

♦ Features of Thick Copper PCB

• • High current carrying capacity: Thick copper reduces resistance, carries 100A current, and improves power density.
  • Strong heat dissipation: Fast heat conduction, temperature rise can be controlled within 40°C.
  • High mechanical strength: Vibration and shock resistance, adaptable to harsh working conditions.
  • High frequency stability: Low signal attenuation, supports high-speed transmission.
  • High reliability: Wide temperature operation (-40°C~150°C), long-term stability.

♦ Applications of Thick Copper PCB

• • ​​Power supply equipment: high-power switching power supply, inverter, UPS, etc.
  • ​​Automotive electronics: electric vehicle motor controller, on-board charger, battery management system.
  • ​​Industrial control: motor driver, servo controller, welding equipment.
  • ​​New energy field: photovoltaic inverter, wind power converter.
  • High-power LED lighting: LED driver board that needs heat dissipation and current carrying.

♦ Typical Application Scenarios of Thick Copper PCB

• • Power conversion equipment: photovoltaic inverters, electric vehicle OBCs and server power supplies use ≥4oz thick copper plates + heat dissipation design to control temperature rise <40℃.

  • Industrial control: PLC, inverters, etc. use double-layer 3oz thick copper plates + blind holes to achieve compact layout.

  • New energy field: energy storage busbars and fuel cell boards use ≥5oz thick copper + nickel plating (≥5μm) for corrosion protection.
