    摘要: To provide a glass containing little B2O3, whereby when its powder is fired, its thermal expansion curve does not have an inflection point, a non-lead glass is provided containing, as represented by mol % based on the following oxides, from 35 to 41.5% of SiO2, from 8 to 25% of MgO, more than 27 to 35% of CaO, from 0 to 2% of SrO, from 0 to 4% of BaO, from 5 to 15% of ZnO and from 4.5 to 10% of Al2O3, wherein the total content of these components is at least 97%, and when SrO and BaO are contained, the total content of SrO and BaO is at most 2%; as well as a non-lead glass containing, as represented by mol % based on the following oxides, from 39.5 to 41.5% of SiO2, from 10 to less than 13% of MgO, from 18 to 22% of CaO, more than 12 to 15% of SrO, from 0 to 1% of BaO, from 6 to 11% of ZnO and from 4.5 to 7% of Al2O3, wherein the total content of these components is at least 97%.

    摘要: An integrated circuit package is mounted on a socket pedestal. External terminals such as ball electrodes may be provided in an array on a mounting surface. Recessed sections can also be provided in the mounting surface in a peripheral section of a region where the external terminals are arranged. The recessed sections can be used for positioning. When the integrated circuit package is subject to an electrical characteristic test (or a burn-in test), the recessed sections can be coupled to protrusions provided on a side of a socket and positioned. As a result, the external terminals can be securely and accurately connected to socket terminals. Thus, integrated circuit packages are provided which have arrayed electrodes for face-down mounting, and which improves the connection accuracy with respect to a socket for conducting electrical characteristic tests.
