Ceramic Printed Circuit Boards

Many users of PCBs find ceramic PCBs have an advantage over traditional PCBs made of other materials. This advantage is because ceramic PCBs provide suitable substrates for electronic circuits with high thermal conductivity and low coefficient of thermal expansion (CTE).

The ceramic PCB is extremely versatile and can replace a complete traditional PCB with a less complex design and increased performance. You can use them in multiple products, like high-power circuits, chip-on-board modules and proximity sensors.

    Main Ceramic PCB Types

    From the level of substrates, ceramic PCBs include the aluminum, AIN, BeO, Si₃N₄, hybrid substrate boards, etc. From the layers of the circuit boards, there are the single-layer, double-layer, and multilayer.
    Ceramic PCBs are usually made up of ceramic cores, with alumina and aluminum nitride (AIN) being two of the primary types. Both of these kinds of boards provide better thermal performance than metal core PCBs because there isn’t a need for an electric layer between the core and the circuits.

    Advantages of Ceramic PCB

    Safe operation in temperatures up to 350 degrees Celsius
    Simple implementation of high-density circuit tracing
    Exceptional high-frequency performance
    Versatile packaging, with an option to come in hermetic packages to prevent water absorption
    Tough chemical erosion resistance
    Another ceramic PCB advantage is a lower overall system cost, which can be especially cost-effective for dense packages, since you have parallel processing of layers.
