Glass powder for preparing copper-based LTCC (Low Temperature Co-Fired Ceramic) substrate, LTCC substrate, preparation method and application
The invention relates to the technical field of ceramic preparation, and particularly discloses glass powder for preparing a copper-based LTCC (Low Temperature Co-Fired Ceramic) substrate, the LTCC substrate, a preparation method and application. 6 to 15 weight percent of CaCO3; siO2 is 34 to 55 weight percent; the content of H3BO3 is 35-30wt%; 0 to 5 weight percent of Al2O3; 0 to 0.8 wt% of ZrO; 0.2 to 2.6 wt% of ZnO; and 50-3 wt% of P2O. By compounding the glass powder and quartz, the prepared LTCC substrate has excellent performance of low dielectric constant, low loss and high expansion, the matching degree is high after the LTCC substrate is co-fired with Cu, and the problem of thermomechanical mismatch caused by co-firing of an existing LTCC substrate and Cu can be avoided.
本发明涉及陶瓷制备技术领域，具体公开了用于制备铜基LTCC基板的玻璃粉及LTCC基板、制备方法和应用，包括以下重量百分比组分：BaCO3 30～42.5wt％；CaCO3 6～15wt％；SiO2 34～55wt％；H3BO35～30wt％；Al2O3 0～5wt％；ZrO 0～0.8wt％；ZnO 0.2～2.6wt％；P2O50～3wt％。本发明通过该玻璃粉与石英复配，制备的LTCC基板具有低介、低损耗、高膨胀的优越性能，与Cu共烧后匹配度高，能够避免现有LTCC基板与Cu共烧导致热机械失配的问题。
