Frequently Asked Questions
What are the primary applications of these thermal management materials?
They are primarily used as raw materials for high-silicon aluminum alloys (with silicon content exceeding 30%) to manufacture electronic packaging substrates, CPU heat dissipation covers, and power module substrates.
How do these materials prevent thermal cycle failure in electronic components?
They feature a low Coefficient of Thermal Expansion (CTE) that closely matches the silicon chip, minimizing mechanical stress and preventing thermal cycle failures during temperature fluctuations.
What makes these materials suitable for aerospace electronics systems?
Their key advantage is their lightweight profile, having only 1/3 the density of copper, combined with high thermal conductivity for rapid heat dissipation.
Which manufacturing processes are compatible with these materials?
These materials support precision molding through powder metallurgy or vacuum hot pressing to ensure high density and low porosity.
Why is low porosity important for electronic packaging substrates?
Low porosity ensures a high-density structure, which maximizes thermal conductivity and enhances the structural integrity of the CPU covers and power module substrates.
