What is aluminum silicon carbide? Silicon aluminum is like aluminum, and silicon carbide ceramic materials are well known and are usually called steel sand. Ordinary millstones, grinders and cutting blades are made of silicon carbide. Its hardness is higher than conical, lower than cubic boron, boron carbide and diamonds. The ceramic material is selected as one of the basic materials of our composite materials. Its high modular and high heating rates are the main factor that people value. The silicon carbide used in Alsic (aluminum silicon) materials is this silicon carbide. The purity of silicon carbide used in composite materials is very high to ensure the high thermal conductivity of the material.
Application of SiAlC in IGBT The bottom plate is directly connected to the radiator, and its main function is dissipating heat. The base plate material must consider the thermal conductivity and linear expansion coefficient (matching the thermal expansion coefficient between the chip and ceramic substrate). AlSiC combines the different advantages of silicon carbide ceramics and metal aluminum, with high thermal conductivity, thermal expansion coefficient matching the chip, low density, lightweight, high hardness, and high bending strength. Therefore, AlSiC materials have become irreplaceable materials in high-power electronic packaging with unique advantages.
Preparation method of aluminum silicon carbide base plate Good selection of the preparation process is crucial to the performance of composite materials. AlSiC, with a volume ratio of 55%~80% in electronic packaging, can meet the requirements. The preparation method of AlSiC substrate consists of two steps: preparation of SiC preform and liquid infiltration of molten aluminum alloy. Among them, preparing SiC preforms is the first and most important step in preparing AlSiC composites. Currently, the preparation methods for prefabricated parts mainly include the following:Molding. Powder injection molding of AFT.Quickest CPC ™ Injection molding technology. The molding method applies to some components with simple structures. The molding mold is simple in manufacture, convenient in operation, short in cycle, pollution-free, high in efficiency, easy to realize automatic production, and more suitable for preparing SiC prefabricated parts. Liquid infiltration methods of a molten aluminum alloy include squeeze casting, vacuum pressure infiltration, vacuum-assisted pressure casting, and non-pressure infiltration.
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.
