Abstract

An ultrasonic vibration bonding resonator includes a resonance body, bonding working portions having a bonding working face and provided at a point of maximum oscillation on upper and lower surfaces of the resonance body and support portions provided at two points of minimum oscillation apart from the bonding working portions to opposite sides in a direction of ultrasonic vibration as projecting from front and back surfaces of the resonance body. Otherwise, it includes a resonance body, tool-attaching portions provided at a point of maximum oscillation on upper and lower surfaces of the resonance body, a bonding working portion having a bonding working face and attached to one of the tool-attaching portions with a screw, support portions provided at two points of minimum oscillation apart from the bonding working portion to opposite sides in a direction of ultrasonic vibration as projecting from front and back surfaces of the resonance body. Furthermore, it may includes a supporting device that includes an upper substrate, two lower substrates separated from each other in forward and backward directions and a resilient body.

Dependent claims

An ultrasonic vibration bonding resonator comprising:

a resonance body;
bonding working portions having a bonding working face and provided at a point of maximum oscillation on upper and lower surfaces of the resonance body;
and
support portions provided at two points of minimum oscillation apart from the bonding working portions to opposite sides in a direction of ultrasonic vibration as projecting from front and back surfaces of the resonance body;
wherein each of the support portions assumes a hexagonal shape, when being seen from a front side, having upper and lower horizontal faces, upper and lower slant faces and right and left vertical faces, and the horizontal faces are in parallel to the bonding working face;
and
wherein an extended line of the upper slant face of the support portion at one of the two points of minimum oscillation apart from the bonding working portions to the opposite sides in the direction of ultrasonic vibration and an extended line of the upper slant face of the support portion at the other of the two points of minimum oscillation intersect at a certain point existing on a perpendicular line relative to the bonding working portion and passing through the point of maximum oscillation, an extended line of the lower slant face of the support portion at one of the two points of minimum oscillation apart from the bonding working portions to the opposite sides in the direction of ultrasonic vibration and an extended line of the lower slant face of the support portion at the other of the two points of minimum oscillation intersect at a certain point existing on the perpendicular line relative to the bonding working portion, which line passes through the point of maximum oscillation, and each of the extended lines of the upper slant faces and the perpendicular line form between them an angle equal to an angle formed between each of the extended lines of the lower slant faces and the perpendicular line.
