♦ 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.
