What is aluminum silicon carbide? Aluminum silicon carbidemetal substrate thermal management composite material is a special electronic packaging material for electronic components. It mainly refers to the combination of aluminum and large -capacity silicon carbide into a low -density, high heating rate and low -expansion coefficient electronic packaging material to solve the thermal failure problem of electronic circuits.
Uses of silicon aluminum carbide Semiconductor industry: air flotation device, vacuum sucker, etc.; RF, microwave, and millimeter wave packaging used in microwave field: mainly used in microwave field; Power packaging mainly refers to high-power devices: power grid, rail transit, new energy vehicles, and other IGBT and MOSFET power module packaging; Complex optoelectronic carrier: photoelectric converter, laser device, etc.; LED: high-power LED; High-performance PCB interlayer: the sandwich of the printed circuit board; Microprocessor cover plate and heat sink: CPU chip.
Preparation of silicon aluminum carbide Dissolve phenolic resin powder in anhydrous ethanol; Add SiC powder into the obtained solution and stir evenly at 40~60 ℃; SiO2 aerogel powder and Al powder are added into the obtained solution in turn, stirred evenly, and then milled for 10-12h; The slurry obtained after ball milling is dried, granulated and screened, and then the particle powder obtained is pressed to form a green body; Put a certain mass of Al2O3 plate on the green body, and sinter it under vacuum 900~1000 ℃ for 1~2h to obtain SiC green body; SiC green body is aluminized in a vacuum of 900~1100 ℃ for 0.5~1h, and then cooled naturally to obtain silicon carbide/aluminum composite. The invention has the advantages of a simple process, convenient operation, low production cost, good product performance, etc. The SiC/Al composite material has good mechanical strength, thermal conductivity, and low thermal expansion coefficient and will have great application prospects in electronic packaging materials.
