Title:
PIEZOELECTRIC VIBRATOR MANUFACTURING METHOD, OSCILLATOR, ELECTRONIC DEVICE AND RADIO-CONTROLLED CLOCK
Document Type and Number:
WIPO Patent Application WO/2010/097904
Kind Code:
A1
Abstract:
A method for manufacturing a piezoelectric vibrator has a step of inserting a core material section of a conductive tack body, which has a flat-board-like base section and the core material section extending along a direction orthogonally intersecting a surface of the base section, into a through hole of a base substrate, and making the base section of the tack body abut to a first surface of the base substrate; a step of applying a paste-like glass flit on a second surface of the base substrate, and filling the through hole with the glass flit by moving in one direction a first squeegee which abuts to the second surface at an attack angle; and a step of filling the through hole with the glass flit excessively applied on the second surface, by moving a second squeegee, which abuts to the second surface at an attack angle, in the direction opposite to the one direction.
