METHOD FOR MANUFACTURING PIEZOELECTRIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric device capable of preventing a poor contact between a pair of lead terminals of a piezoelectric vibrator and a substrate.SOLUTION: A method for manufacturing a piezoelectric device comprises the steps of: coating a case region corresponding to a metal case and a lead region corresponding to a third portion with a cream solder on a surface of a substrate (S102); installing a block solder having a smaller area than the case region in the case region (S103); arranging a metal case of a piezoelectric vibrator in the case region and the third portion in the lead region (S104); and heating the substrate and the piezoelectric vibrator in a reflow furnace (S105). A lead terminal includes a first portion pulled out horizontally in a longitudinal direction of the metal case, a second portion bent vertically in the longitudinal direction, and a third portion rebent in the longitudinal direction.
