  • Pros And Cons Of Using Ceramic PCBs - DemotiX

    2021-3-31 · Since ceramic has excellent thermal conductivity, the circuit board will perform better in situations where the device is in contact with excessive heat. The ceramic will protect the device from getting damaged and even control the temperature. When the device has a multi-layered ceramic PCB, it will give it even more protection from heat. Cons:
