Thick copper PCB has unique advantages in some specific electronic applications.

The main feature of thick copper PCB is that its copper foil thickness is relatively large, usually much higher than that of ordinary PCB. This makes thick copper PCB have better conductivity and current carrying capacity. For example, in high-power power supplies, motor drives, and other fields, thick copper PCB can withstand large currents, reduce circuit resistance and heat generation, and improve system efficiency and reliability.

In terms of design, thick copper PCB needs to consider heat dissipation issues. Due to the thick copper foil, a significant amount of heat is generated during operation. Therefore, it is necessary to design heat dissipation channels and structures reasonably to ensure that the temperature of the PCB is within a safe range. For example, heat dissipation holes, heat sinks, or using high thermal conductivity boards can be added to the PCB to improve the heat dissipation effect.

Manufacturing thick copper PCB has certain difficulties. Due to the thicker copper foil, higher pressure and energy are required during the processing to ensure a strong bond between the copper foil and the board. At the same time, the etching and drilling processes of thick copper PCB also require special equipment and technology to ensure processing accuracy and quality.

The application fields of thick copper PCB mainly include high-power electronic devices, industrial control, automotive electronics, etc. In these fields, thick copper PCB can meet the requirements for high current and high reliability. For example, in the battery management system of electric vehicles, thick copper PCB can withstand high current charging and discharging, ensuring the safety and performance of the battery.

In short, thick copper PCB plays an important role in specific electronic applications due to its excellent conductivity, current carrying capacity, and heat dissipation performance. With the continuous development of high-power electronic devices, the demand for thick copper PCB will gradually increase.
