ABSTRACT:
An alignment apparatus is provided for ensuring proper positioning of a wire bonding capillary during installation of the wire bonding capillary onto the horn of a wire bonding machine. The apparatus ensures that the capillary is in a correct position relative to its longitudinal axis and is also in a desired rotational position with respect to the horn. The apparatus includes a first arm and a second arm which are movable toward each other to engage an outer surface of the horn thereby gripping the horn between the first and second arms. The apparatus also includes a support for holding the capillary. When the apparatus is properly positioned on the horn the support holds the capillary in a predetermined position in which the capillary is properly aligned with respect to the horn. A locking mechanism of the horn may then,be used to lock the capillary onto the horn.
