  • Wire tensioning apparatus
    Patent number: 6520400
    Abstract: A device and method for providing tension and a reserve wire reservoir to a bonding wire for use with a bonding machine. The device includes an outlet port providing fluid under pressure, and a surface along which the pressurized fluid flows in a direction away from the outlet port such that the bonding wire follows a path along the surface and the pressurized fluid places a uni-directional tension on the bonding wire while maintaining a reserve portion of wire in a slack loop.
    Type: Grant
    Filed: March 30, 2001
    Date of Patent: February 18, 2003
    Assignee: Kulicke & Soffa Investments, Inc.

  • Indirect imaging system for a bonding tool
    Publication number: 20030019908
    Abstract: A vision system and method for use with a bonding tool that takes into account variations due to temperature changes and other nonrandom systemic effects. The vision system includes a cornercube offset tool having a plurality of total internal reflection surfaces, the cornercube offset tool located below the vision plane of the optical system; and an optical detector to receive an indirect image of the bonding tool through the cornercube offset tool. The method comprises the steps of providing a cornercube offset tool having a plurality of total internal reflection surfaces below a vision plane of the bonding tool; and receiving an indirect image of the bonding tool through the cornercube offset tool.
