    Electronic Packaging and Thermal Management Materials
    Core Application

    As a raw material for high-silicon aluminum alloys (such as Si content of more than 30%), it is used to prepare electronic packaging substrates, CPU heat dissipation covers, and power module substrates.

    Performance Advantages

    Low CTE matching silicon chip to avoid thermal cycle failure; High thermal conductivity and rapid heat export; Lightweight (only 1/3 the density of copper) for aerospace electronics systems.

    Process Support

    Molding by powder metallurgy or vacuum hot pressing to ensure low porosity and high density.

    Frequently Asked Questions (FAQ)
    What are the primary applications of these thermal management materials?

    They are used as raw materials for high-silicon aluminum alloys (with a silicon content exceeding 30%) to prepare electronic packaging substrates, CPU heat dissipation covers, and power module substrates.

    Why is a low CTE important for electronic packaging?

    A low Coefficient of Thermal Expansion (CTE) matches the silicon chip, which helps prevent thermal cycle failure during temperature fluctuations.

    What makes these materials suitable for aerospace electronics?

    These materials are lightweight, with a density that is only 1/3 of copper, making them ideal for weight-sensitive aerospace electronics systems while still offering high thermal conductivity.

    What manufacturing processes are supported for these materials?

    They support molding processes such as powder metallurgy and vacuum hot pressing, which ensure low porosity and high density in the final product.

    How does the thermal conductivity performance benefit the system?

    The high thermal conductivity of these materials allows for rapid heat export, which protects sensitive electronics from overheating.
