ABSTRACT:
A piezoelectric resonator is formed with a case and a stem for housing the piezoelectric vibrating portion thereof. The case and stem are coupled by press-fitting and the interface is coated with a high temperature solder containing at least 90% lead. An inner lead of the resonator is also coated with the solder and a portion of the vibrator is fixed to the lead by melting the solder. Alternative constructions employ a resin case or a metallic plate case and a configuration in which an integrated circuit and a piezoelectric vibrator are integrally molded to achieve a highly desirable mounting configuration.
