  • Threading tool and method for bond wire capillary tubes
    Patent number: 6789721
    Abstract: A capillary threading tool is used to thread bond wire through the capillary tool of a wire bond machine. The capillary threading tool includes a handle that is grasped to manipulate a body portion into a gap between the upper end of the capillary tube and the lower end of a guide tube that is positioned above the capillary tube. The body portion includes a guide surface that is placed in contact with the wire bond machine, and a vertical slot extending from the guide surface that terminates in a closed end having an inclined surface. The length of the slot is selected to position the lower edge of the inclined surface above the end of the capillary tube so the bond wire can be threaded into the capillary tube simply by forcing the end of the wire on the inclined surface.
    Type: Grant
