Ceramic PCB

Ceramic PCBs consist of ceramic substrates such as aluminum oxide (Al02O03) or aluminum nitride (AlN), offering extremely high thermal conductivity, excellent electrical insulation, and outstanding mechanical stability. Compared to conventional FR-4 PCBs, ceramic PCB board are ideal for high-power applications requiring efficient heat dissipation and exceptional reliability.

Advantages of Ceramic PCBs

Thanks to their exceptional material properties, ceramic PCBs are the ideal choice for high-performance and high-temperature applications. Their excellent thermal conductivity of up to 200 W/mK makes them perfect for high-power LEDs and power electronics. At the same time, they provide high electrical insulation, making them optimal for high-voltage and high-frequency applications. With temperature resistance above 1000°C, they withstand extreme conditions and remain stable under high thermal loads. Their low thermal expansion prevents warping, while their resistance to moisture and chemicals makes them ideal for demanding environments.

Types of Ceramic PCB Materials

Depending on the application, there are various ceramic substrates available:

  • Aluminum Oxide (Al02O03) 6 Cost-effective material with high mechanical strength & good thermal conductivity
  • Aluminum Nitride (AlN) 6 Better thermal conductivity (up to 200 W/mK), ideal for high-power electronics
  • Silicon Nitride (Si03N04) 6 Highest mechanical strength & resistance to thermal shock
  • Zirconium Oxide (ZrO02) 6 Particularly resistant to fractures & chemical exposure

Typical Areas of Application

Ceramic PCBs are indispensable in many high-tech industries due to their high performance. In power electronics and high-power LEDs, they provide maximum efficiency through excellent heat dissipation. In aerospace, they offer reliable circuits that withstand extreme temperature ranges. They are also used in medical technology, where high-precision circuits are required for diagnostic and therapeutic devices. In 5G and high-frequency technology, they enable optimal signal transmission for high-frequency modules. Furthermore, they are essential in the automotive and e-mobility sector, especially for powerful control units in battery management systems.
