Abstract

The invention provides a packaging glass. The packaging glass comprises, by weight, 55-75% of SiO2, 2-15% of Al2O3, 10-20% of B2O3, 0-12% of Li2O, 0-10% of Na2O and 0-10% of K2O, wherein the content ratio of Al2O3/B2O3 is 0.17-1.2, and the content of 3.5K2O + 4.5Na2O + 6Li2O is 40-70%. Through reasonable component design, the obtained glass is low in transition temperature and excellent in chemical stability, the coefficient of linear expansion can be matched with that of ceramic, and the glass is suitable for the field of ceramic packaging.

Description

technical field [0001] The invention relates to an electronic package material, in particular to a package glass used in a microelectronic ceramic package, and a package component made of the package glass. Background technique [0002] Ceramic packaging technology has the characteristics of good air tightness, high chemical stability, high mechanical strength and simple packaging process, and has broad market prospects and development space. In ceramic packaging technology, the packaging glass can be used as the solder glass for fusing the ceramic base and the upper cover. The glass used in the packaging field must meet the following performance requirements: 1) The linear expansion coefficient of the glass can match the ceramics to be welded, so as to ensure that the airtightness of the packaging components is not damaged under different operating temperatures; 2) The chemical stability of the glass Excellent to ensure the durability of the packaged components when in con...
