What is aluminum silicon carbide? Aluminum silicon carbide(AlSiC) metal matrix thermal management composite is a special electronic packaging material for electronic components. It mainly refers to the combination of aluminum and a high volume fraction of silicon carbide into electronic packaging materials with low density, high thermal conductivity, and low expansion coefficient to solve the thermal failure problem of electronic circuits.
Overview of characteristics of silicon aluminum carbide AlSiC has high thermal conductivity (170~200W/mK) and adjustable thermal expansion coefficient (6.5~9.5 × 10-6/K), so on the one hand, the thermal expansion coefficient of AlSiC is well matched with the semiconductor chip and ceramic substrate, which can prevent the generation of fatigue failure, and even install the power chip directly on the AlSiC substrate; On the other hand, the thermal conductivity of AlSiC is ten times that of Kovar alloy, and the heat generated by the chip can be released in time. In this way, the reliability and stability of the whole component are greatly improved. AlSiC is a composite material, and its thermal expansion coefficient and other properties can be adjusted by changing its composition. Therefore, electronic products can be flexibly designed according to the user's requirements and truly tailored, which is impossible for traditional metal or ceramic materials.
Uses of silicon aluminum carbide Because AlSiC electronic packaging materials and components have the advantages of high elastic modulus, high thermal conductivity, and low density, and the expansion coefficient can be adjusted by the volume fraction of SiC and the amount of adhesive added to achieve the thermal matching with GaAs chips and alumina substrates; At the same time, the components with complex shapes can be nearly net formed, so the production cost is also low, which makes it widely used in the fields of integrated microwave circuits, power modules, micro-processor cover plates, and heat dissipation plates. Compared with aluminum matrix composites used as structural materials, the mechanical properties of AlSiC electronic packaging materials are rarely studied. If they are used as packaging materials, their mechanical properties are also important data for structural design.
