ABSTRACT:
A capillary holder is provided for holding a wire bonding capillary. The holder has a base and an extension extending therefrom to hold the capillary by contacting the capillary at at least two points. The extension can hold the capillary by frictional contact with either an inner or outer surface of the capillary. The base can either constitute a drive element or be coupled to a drive element which can be rotated by a rotation element. This imparts rotation to a capillary held by the capillary holder.
