“The key technology research and application of microwave high Q multilayer ceramic capacitors for 5G communications” project has solved the problem of gelation of low melting point Dielectric Powders in the process of porcelain slurry configuration. The amount of residual carbon in the rubber discharge process is reduced by humidifying in nitrogen; A method for testing MLCC high frequency parameters is developed.
