High Temperature Alumina Ceramic Roller Company Introduces You To What Is High Frequency Porcelain

Time:2018/9/4 16:23:40 Click on:

Commonly used high-frequency porcelains are high-aluminum porcelain, talc-like porcelain, etc. With the development of the electronics industry, especially the thick film, thin-film circuits and microwave integrated circuits, higher requirements have been placed on packaged ceramics and substrates. Many new varieties, such as oxidized enamel and boron nitride ceramics, are being developed to develop aluminum nitride and silicon carbide ceramics. Their common feature is higher thermal conductivity.

High-frequency porcelain is an insulating ceramic, also known as ceramic, which is mainly used for mounting, fixing and protecting components of electronic equipment, and provides insulating support for current-carrying conductors and ceramics of various integrated circuit substrates. Low dielectric constant, low dielectric loss, high mechanical strength, high dielectric strength, insulation resistance and thermal conductivity, etc. High alumina ceramics mainly include dielectric ceramics, talc porcelain, etc.

With the development of the electronics industry, especially thick film and thin film circuits and microwave integrated circuits, higher requirements are placed on ceramic packaging and substrates. There are many new varieties, such as yttria ceramics, boron nitride ceramics, and the like. The high temperature alumina ceramic roller company tells you that the current development of aluminum nitride ceramics and the research of silicon carbide ceramics, their common feature is high thermal conductivity.

High-frequency porcelain is mainly composed of alpha-alumina, which contains more than 75% of various types of ceramics. With excellent mechanical and electrical properties, it is one of the most widely used high-frequency insulating ceramics. It can be used for high-power insulation parts of ultra-high frequency and vacuum electronic components, ceramic tube shells for vacuum condensers, microwave ceramic component windows and various multimedia ceramic substrates, such as talc porcelain and natural minerals. The pyroxene is the main crystalline ceramic, excellent dielectric properties and low price. The disadvantages are large thermal expansion coefficient, poor thermal stability and low strength. It is widely used in the manufacture of switches, sockets, adjustable capacitor assemblies and shafts, porcelain plates, variable inductance coil bobbins, and skeletons.
