A transducer is provided that comprises a horn that is configured to transmit vibrations along its length during operation in the form of an oscillatory waveform, such oscillatory waveform having a plurality of vibration nodal points. An ultrasonic generator is coupled to one end of the horn and a bonding tool is coupled to an opposite end of the horn for performing bonding operations. A first flange structure is located along the length of the horn at a first vibration nodal point for mounting the transducer, and a second flange structure is located along the length of the horn at a second vibration nodal point for mounting the transducer, such that the second flange structure is separated from the first flange structure by a distance of at least two consecutive vibration nodal points.

Flanged transducer having improved rigidity

A bonding apparatus is provided comprising a bonding stage for holding a bonding tool, an air distribution system mounted to the bonding stage and an air inlet attached to the air distribution system. The air distribution system is connected to the air inlet for receiving air from the air inlet, and is operative to pass the air over multiple surfaces of the bonding stage for the purpose of temperature control.

Temperature control of a bonding stage

A thermal insulation system is provided for a component of a bonding system, such as an optical system. The thermal insulation system comprises multiple insulation layers located between the component and a heat source. The multiple insulation layers comprise at least one layer of moving air injected into the layer and a cover layer enclosing the layer of moving air. The multiple insulation layers may further comprise a layer of static air.

Multi-layer thermal insulation for a bonding system

A capillary holder for mounting a capillary onto a horn is provided that comprises a mounting hole formed in the horn that has a first width along a first axis that is smaller than a width of the capillary and a second width along a second axis perpendicular to the first axis that is larger than the width of the capillary. In particular, the mounting hole is configured such that application of a flexion force to reduce the second width simultaneously expands the first width so as to fit the capillary when the first width is larger than the width of the capillary, and removal of said flexion force contracts the first width whereby to grip the capillary using an elastic force of the horn.
