MOUNT STRUCTURE OF PIEZOELECTRIC VIBRATOR, PIEZOELECTRIC VIBRATOR UNIT USING THE STRUCTURE AND OSCILLATOR

摘要

PROBLEM TO BE SOLVED: To secure electrical connection between the electrodes of a mount part and a piezoelectric vibrator with high reliability and without increasing the cost nor deteriorating the impact resistance. ;SOLUTION: An anisotropic conductive material 90 is used for a piezoelectric vibrator unit 1 to secure electrical and mechanical connection between a mount part 40 and an end part 61 of a piezoelectric vibrator 60. A 1st anisotropic conductive material 90A to which a small diameter conductive grain is mixed is used to secure connection between a tip part 611 of the part 61 of the vibrator 60 and the part 40. A 2nd anisotropic conductive material 90B to which a large diameter conductive grain is mixed is used to secure connection between the par 40 and an inside part 612 adjacent to the part 611. Then the vibrator 60 is obliquely fixed.;COPYRIGHT: (C)2000,JPO
