Copper-based PCBs

Copper-based PCBs consist of a metal core structure with a solid or coated copper layer offering superior thermal conductivity and high electrical performance. Compared to FR-4 or aluminum PCBs, copper PCBs provide even more efficient heat dissipation, making them ideal for power electronics, high-current applications, and high-power LEDs.

Advantages of Copper-based PCBs

Copper-based PCBs offer outstanding performance due to their excellent thermal and current conductivity. These properties make them particularly suitable for high-power applications. Their extremely high thermal conductivity makes them ideal for high-power LEDs and powerful electronic components. Copper also provides excellent current-carrying capability, allowing for higher current loads. The effective heat management reduces hotspots on the board and significantly extends the lifespan of components. Furthermore, copper PCBs are especially robust, durable, and have high mechanical strength and corrosion resistance. They are also suitable for high-temperature applications, withstanding temperatures up to 30000b0C.

Types of Copper-based PCBs

Depending on the application and technical requirements, there are various types of copper-based PCBs:

  • Solid Copper PCBs provide particularly high thermal conductivity and current-carrying capacity, suitable for extremely powerful applications.
  • Copper Core PCBs are metal-core PCBs with a copper base for improved heat dissipation and protecting thermally sensitive components.
  • Copper-clad PCBs have a thin copper layer for optimized thermal performance, suitable for specific design requirements.
  • Multilayer Copper PCBs allow for complex and powerful circuits and are used in cutting-edge electronic systems.

Typical Areas of Application

Copper-based PCBs are used in many high-performance industries. In power electronics and high-current technology, they are used for power supplies, converters, and inverters. In high-power LED technology, they play a central role in LED drivers and lighting systems. They are also indispensable in the automotive industry and electromobility, particularly in battery management systems (BMS) and high-current PCBs. In industrial and automation technology, they are used in powerful controls and high-temperature circuits. Additionally, they are used in aerospace for resilient electronics in extreme environments.
