Piezoelectric oscillator unit |
摘要 |
A piezoelectric oscillator unit maintains the adhesive force of a quartz vibrator package with respect to a circuit substrate even when the solder connecting the quartz vibrator package to the circuit substrate melts. This prevents the vibrator package from lifting from or falling off of the circuit substrate. In this piezoelectric oscillator unit, a quartz vibrator housing a quartz member is overlaid on a box-shaped circuit substrate on which an oscillating circuit, a temperature compensation circuit, or other circuits are mounted. The electrodes provided on the four corners of the top surface of the circuit substrate and the electrodes provided on the four corners of the bottom surface of the quartz vibrator are bonded together using solder, and also the circuit substrate and the quartz vibrator are mechanically coupled by an adhesive.
