  • Patent number: 5189507
    Abstract: The invention provides a technique for interconnecting electronic components in which interconnection wires are bonded to contacts on a first component without the use of a material other than the materials of the contacts and the wires; the wires are then severed to a desired length of between 2d and 20d, where d is the diameter of the wires, and bonded to contacts on the second component by means of a conductive material such as solder. Preferably, solder is provided as pools located in recesses in a layer of insulating material. The invention also provides a bonding head for a wire bonder for bonding the wire to the contact on the first component and for weakening or severing the wire at the desired point.
