High-frequency insulating ceramics, also known as device ceramics, are used in electronic equipment to install, fix, and protect components, as insulating supports for current-carrying conductors, and as ceramics for various integrated circuit substrates. Small dielectric constant, low dielectric loss, high mechanical strength, and high dielectric strength, insulation resistance and thermal conductivity. Commonly used high-frequency insulating ceramics include high-alumina ceramics and steatite ceramics.
The higher the purity of alumina ceramics, the more optimized the performance of the plate. For example, the dielectric constant of 99 ceramics is more stable than that of 95 ceramics, because the purity of the plate is better and there are fewer impurities. The heat conduction and heat dissipation ability is also better, but the use of 99 ceramics is more expensive than 95 ceramics. Generally, 96 ceramics is considered a better ceramic substrate. High-end products require higher purity of the plate, so you can choose 99 alumina ceramics Substrate processing ceramic circuit board or ceramic copper clad laminate.
In addition, we also provide ceramic parts made of cordierite and zirconia for different applications.
