    • The present invention provides a method of fabricating a crystal oscillator with pedestal for surface mounting, which is provided on a base surface of a crystal oscillator from which a pair of lead wires extends and which is formed by injection molding using a mold with a liquid-crystal polymer as raw material; wherein protrusions that follow the shape of said mold are provided on at least a corner around the outer periphery of the surface of the oscillator pedestal facing said base surface of said crystal oscillator; a non-defective product is assumed to be one in which the upper surface of each of said protrusions is a flat surface, but a defective product is assumed to be one in which the flat surface of said protrusion is ridged; and only a non-defective product is mounted onto the base surface of the crystal oscillator. This makes it possible to provide a method of fabricating a crystal oscillator by which reliability is increased while the strength of the oscillator pedestal is maintained.
    • 本发明提供了一种制造具有用于表面安装的基座的晶体振荡器的方法,该晶体振荡器设置在晶体振荡器的基底表面上,一对引线从该晶体振荡器的基底表面延伸,并且通过使用具有液体 - 晶体聚合物为原料; 其特征在于,在与所述晶体振子的所述基面相对的所述振荡台的表面的外周的至少一个角上设置有跟随所述模具形状的突起; 假设无缺陷产品是其中每个所述突起的上表面是平坦表面的缺陷产品,但是假设缺陷产品是其中所述突起的平坦表面被脊化的缺陷产品; 并且只有无缺陷的产品安装在晶体振荡器的基面上。 这使得可以提供制造在保持振荡器基座的强度的同时提高可靠性的晶体振荡器的方法。
