Description

technical field [0001] The invention relates to a low-dielectric and high-frequency glass-ceramic LTCC material and a preparation method thereof, belonging to the technical field of electronic ceramics and its preparation. Background technique [0002] With the continuous development of electronic information technology in the direction of high frequency and digitalization, the requirements for miniaturization, integration and modularization of components are becoming increasingly urgent. Low Temperature Co-fired Ceramics (LTCC) technology is Electrical, mechanical, thermal, process characteristics, and high reliability have become one of the main technologies for electronic device modularization. LTCC technology requires microwave dielectric ceramics to be co-fired with Ag and Cu internal electrodes with high conductivity and low melting point. Therefore, low-temperature sintering of microwave dielectric ceramic materials has become a research hotspot. Traditional ceramic ...
