What is thick copper PCB? 

Thick copper PCB is a special printed circuit board specifically designed for high-power applications. It uses a thicker copper foil layer than standard PCBs, with a thickness typically ranging from 3 ounces (approximately 105 micrometers) to 20 ounces (approximately 700 micrometers). This enhanced copper thickness gives PCBs higher current-carrying capacity, better thermal management performance, and stronger mechanical strength, thereby providing higher performance and reliability in harsh environments. Thick copper PCBs are widely used in power equipment, automotive electrical systems, industrial mechanical automation, and military and aerospace electronic devices that require high current and good thermal stability. This PCB is designed to meet the needs of high-current applications while reducing hotspots, protecting electronic components from overheating damage, and ensuring the stable operation of electronic devices in harsh environments.

The functions of copper-clad PCB boards 

Our copper-clad PCB products feature a thicker copper layer than standard PCBs, enabling them to handle higher currents and enhance heat dissipation performance. This characteristic makes our copper-clad PCBs the ideal choice for various demanding applications, especially those with strict requirements for high power, thermal management, and mechanical elasticity. As a reputable thick-copper PCB manufacturer, the circuit boards we produce possess the following functions: 

High current capacity: Thick copper PCBs can handle higher currents than standard PCBs. This capability helps prevent overheating and ensures reliable operation even in high-power applications. They are suitable for power supplies, motor controllers, and power converters. 

Heat dissipation: The thick copper layers in the thick copper PCB board help achieve excellent heat dissipation, thereby reducing the risk of heat accumulation. The additional copper layers can more effectively conduct and disperse heat, keeping the components cool. This makes them ideal choices for applications such as LED lighting systems, power amplifiers, and electric vehicles. 

Enhancing strength: The increased copper thickness provides PCBs with greater mechanical strength, enhancing durability and thermal cycling resistance. Therefore, they are also commonly used in industrial automation, military, and aerospace applications. 

Compact power distribution: Copper-clad PCBs can integrate high-power circuits in a compact design. Therefore, they are widely used in compact power distribution units, UPS systems, and other equipment.
