♦ 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

• • ​​​​Large current carrying capacity: copper thickness ≥3oz, can pass 100A+ current, low temperature rise.

  • ​​Strong heat dissipation: high thermal conductivity, heat dissipation efficiency increased by 5 times+, temperature rise reduced by 10-15℃.

  • ​​High mechanical strength: bending resistance increased by 50%, high temperature vibration resistance, adaptable to harsh environments.

  • ​​Electrical stability: low impedance, low loss, low risk of delamination at high temperature.

  • ​​Flexible design: supports wide line width (≥100mil) and multi-layer thick copper stacking.

  • ​​Complex process: etching/drilling is difficult, yield rate is 85%-90%.

  • ​​High cost: material + processing premium is 30%-50%, and the unit price is high.

♦ 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.
