What is aluminum silicon carbide? Aluminum silicon carbide is a kind of aluminum alloy as the matrix of particle reinforced metal matrix composites. According to the design requirements, with SiC particles as the reinforcement, in a certain form, proportion and distribution state, the formation of a multi-component composite material with obvious interface, with a single metal does not have comprehensive, superior performance.
Performance characteristics of silicon aluminum carbide LSiC has high thermal conductivity (180~240W/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, the product can be flexibly designed according to the user's requirements and truly tailored, which is impossible for traditional metal or ceramic materials.
Material significance of silicon aluminum carbide It can greatly improve the packaging performance of integrated circuits. The use of aluminum silicon carbide materials for electronic packaging can make the package body consistent with the thermal expansion of the chip, play a good heat conduction function, and solve the thermal failure problem of the circuit; Bulk use of AlSiC materials can reduce the packaging cost, which is much cheaper than the current use of W-Cu, Mo and other precious metal materials; Effectively improve the packaging technology level of China's aerospace, military, microwave and other power microelectronics fields, improve functions, reduce costs, and accelerate the pre-evolution of China's aerospace and military products. For example, in the past, when the Kovar material was used as the device packaging shell, if the aluminum-silicon carbide shell were replaced, the weight would be reduced by one-third of the original, and the thermal conductivity would be increased by ten times.
Price of aluminum silicon carbide Aluminum silicon carbide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of aluminum silicon carbide. A large amount of large amount will be lower. The price of aluminum silicon carbide can be found on our company's official website.
