  • Method of fabricating hermetic terminal and hermetic terminal, method of fabricating piezoelectric oscillator and piezoelectric oscillator, oscillator, electronic appliance, and radio clock
    Patent number: 7719171
    Abstract: A method of fabricating a hermetic terminal having an annular ring, a lead arranged to penetrate through the ring in which one end side thereof is an inner lead portion electrically connected to a piezoelectric vibrating piece and the other end side thereof is an outer lead portion electrically connected to outside as the ring is between them, and a filler fixing the lead to the ring, wherein the hermetic terminal seals the piezoelectric vibrating piece inside a case, the method includes the steps of: applying plating to a hermetic terminal intermediate having the lead fixed in the ring with the filler to plate the ring and the lead; setting the hermetic terminal intermediate after subjected to plating on a holding member; and flattening an end part of an inner lead portion in the lead to form a stair portion in the hermetic terminal intermediate set on the holding member.
