  • Device for welding a wire by means of thermo-compression bonding
    Patent number: 3950631
    Abstract: A device for connecting a wire to a support, for example a semiconductor device, by means of thermocompression bonding, by buttwelding, has a movable tool for holding the wire while one end is exposed. An electrode is spaced from the wire end and means are provided for producing a high electric voltage between the electrode and the wire end so as to produce a spark discharge therebetween sufficient to melt the wire end and form a ball. The tool is then used to cause thermocompression bonding.
