Heavy Copper PCB
Thick copper PCB is a special printed circuit board designed for high-power applications. It uses a thicker copper foil layer than standard PCBs, with a thickness usually ranging from 3 ounces (about 105 microns) to 20 ounces (about 700 microns).
What is Heavy Copper PCB?
Thick copper PCB is a special printed circuit board designed for high-power applications. It uses a thicker copper foil layer than standard PCBs, with a thickness usually ranging from 3 ounces (about 105 microns) to 20 ounces (about 700 microns). This enhanced copper thickness gives the PCB a higher current carrying capacity, better thermal management performance, and stronger mechanical strength, thereby providing higher performance and reliability in demanding environments. Thick copper PCBs are widely used in power supply equipment, automotive electric systems, industrial machine automation, and military and avionics equipment that require high current and good thermal stability. This PCB is designed to meet the needs of high-current applications while reducing hot spots, protecting electronic components from overheating damage, and ensuring the stable operation of electronic equipment under

Functions of copper-clad PCB Board
Our copper-clad PCB board products utilize thicker copper layers compared to standard PCBs, enabling them to manage higher currents and offer enhanced heat dissipation. This characteristic positions our copper-clad PCB board as an optimal choice for a variety of demanding applications, particularly those demanding high power, thermal management, and mechanical resilience. As reputable heavy copper PCB manufacturers, we fabricate boards equipped with the following functionalities:
High Current Capacity
Heavy copper PCBs are able to carry higher currents than standard PCBs. This capacity helps prevent overheating and ensures reliable operation even in high-power applications. These are suitable for power supplies, motor controllers, and power converters.
Heat Dissipation
The substantial copper layers in heavy copper PCBs facilitate superior heat dissipation, mitigating the risk of thermal accumulation. The additional copper conducts and spreads heat more effectively, keeping components cool. This makes them ideal for applications such as LED lighting systems, power amplifiers, and electric vehicles.
Improved Strength
The augmented copper thickness imparts greater mechanical strength to the PCB, enhancing durability and resistance to thermal cycling. Because of this, these are also commonly used in industrial automation, military, and aerospace applications.
Compact Power Distribution
Copper-clad PCBs enable the integration of high-power circuits within a compact design. That’s why these are used in compact power distribution units, UPS systems, and other devices.
