Resonator, ultrasonic die bonding head, and ultrasonic die bonding apparatus

摘要

A resonator 1 of the present invention includes: a vibrating member 13 holding an electronic component 12 and applying a vibration to the electronic component 12; and a depressing member 15 applying a depressing force for a side of a substrate 11 to the electronic component 12 through the vibrating member 13. The depressing member 15 includes: leg portions 15b which are disposed so as to leave spaces between the leg portions and both side faces 13a of the vibrating member 13 parallel with a vibration direction A; and supporting portions 15c through which the leg portions 15b and the side faces 13a of the vibrating member 13 are to be coupled to each other. With respect to a size of a cross section of each of the supporting portions 15c parallel with the side face 13a of the vibrating member 13, a length L2 along the vibration direction A of the vibrating member 13 is shorter than a length L1 along a depressing direction B of the depressing member 15.
