    FAQ

    Q: What are the advantages of alumina ceramic heat dissipation substrates compared to aluminum substrates?
    A: They offer better insulation, higher heat resistance, and better matched thermal expansion coefficients, making them particularly suitable for heat dissipation in high-power devices.

    Q: What is the service life of filtration components?
    A: Depending on the usage environment, generally 6-24 months, and service life can be extended through backwashing.

    Q: Is customization of porosity and filtration accuracy supported?
    A: Yes, customized pore structures and filtration accuracy are available according to customer requirements.

    Q: How to test the performance of heat dissipation substrates?
    A: Thermal resistance can be measured using a thermal resistance tester, or temperature distribution can be observed using an infrared thermal imager.
