Abstract: A bonding arm swinging type bonding apparatus that has a rotational center 13 of the bonding arm 1 beneath the bonding arm. The rotating shaft parts 11 of circular arc form rotary motors 10 that rotate about the rotational center 13 of the bonding arm 1 are attached to the bonding arm 1, and the rotating shaft parts 21 of circular arc form air bearings 20 that rotate about this rotational center 13 are provided so that the rotating shaft parts of the circular arc form air bearings 20 are rotatable as a unit with the rotating shaft parts 11 of the rotary motors 10.

Abstract: A bonding apparatus including a front link whose lower end is rotatably connected to a bonding arm and upper portion is rotatably connected to bonding head, and a rear link whose lower end is rotatably connected to the rear end of the bonding arm and upper portion is rotatably connected to the bonding head; and a hypothetical rotational center of capillary of the bonding arm is on a bonding surface and set to be the intersection of a line that connects upper and lower rotational centers of the front link and a line that connects upper and lower rotational centers of the rear link, wherein the immovable element of motor is fastened to the bonding head, and the rotational element of the motor is attached to the upper end of the rear link so that the rotational element rotates about the upper rotational center of the rear link.

Abstract: A transducer vibrated by a vibrator and used in a bonding apparatus, the transducer including holding portions and connecting portions. The holding portions are provided so as to protrude at at least two locations that correspond to the nodes of vibration of a transducer main body, and the connecting portions each connects the tip ends of two protruding holding portions to each other. The external force applied to one of the holding portions is thus dispersed in each of the respective holding portions connected by the connecting portions, deformation of the holding portions is prevented, and the respective holding portions can be formed extremely thin in the axial direction of the transducer main body.
