electronic packaging silicon aluminum alloy | aluminum silicon carbide
Aluminum silicon carbide (AlSiC) is the abbreviation of aluminum-based silicon carbide particle reinforced composite material. It fully combines the different advantages of silicon carbide ceramics and metal aluminum. It has high thermal conductivity, a thermal expansion coefficient that matches the chip, low density, and light weight. , as well as high hardness and high flexural strength.
Aluminum silicon carbide packaging material meets the requirements of lightweight and high-density packaging. It is suitable for aviation, aerospace, high-speed rail and microwave fields. It is the first choice for solving thermal management problems. It can be used for various microwave and microelectronics and power Packaging and assembly of devices, optoelectronic devices provides the required thermal management.
A brief description of silicon aluminum alloy
Silicon aluminum alloy is a binary alloy composed of silicon and aluminum. It is an alloy material mainly used in aerospace, space technology and portable electronic devices. The silicon-aluminum alloy material can maintain the excellent properties of silicon and aluminum, and the content of silicon and aluminum is quite rich. The preparation technology of silicon powder is mature and the cost is low. At the same time, this material does not pollute the environment and is harmless to the human body. The density of silicon aluminum alloy is between 2.4~2.7 g/cm³, and the coefficient of thermal expansion (CTE) is between 7-20ppm/℃. Increasing the silicon content can significantly reduce the density and thermal expansion coefficient of the alloy material.
What can high silicon aluminum alloy be used for?
High-silicon aluminum alloys are mainly used in electronic packaging, and exert excellent performance in the packaging of microwave power devices, integrated power modules, and other electronic power devices. Using high-silicon aluminum alloy as the base, shell, box, and cover plate of the electronic packaging material has good matching, can provide better heat dissipation, can greatly prolong the service life of the packaged high-power module, and increase the reliability. The material has the characteristics of light weight, high thermal conductivity, low thermal expansion, high stiffness, good mechanical processing and surface plating performance and welding performance, good material compactness, high temperature resistance, corrosion resistance and so on.
