PACKAGE FOR SURFACE MOUNTING TYPE PIEZOELECTRIC VIBRATOR AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a surface mounting type piezoelectric vibrator which can be more miniaturized while enhancing shield effect and securing a housing space for a piezoelectric diaphragm and can improve the reliability of hermetic sealing. SOLUTION: Constellations are vertically formed on four corners of the outer periphery of a ceramic package. Under constellations C1 and C2 among these constellations, metal conductors 14 and 15 are formed and the relevant metal conductors 14 and 15 are electrically connected with an electrode pad. Besides, metal conductors 16 and 17 are formed from the upper ends to the lower ends of castellation C3 and C4 and electrically connected with a metal layer 11 and ground terminals E3 and E4 formed on the base of the ceramic package.
