Danach wird die Nadel 5 abgesenkt und mit leichtem Druck auf die zu verbindenden Teile aufgesetzt. Zur Durchführung der Lötung werden mittels der Nadel 5 den zu verbindenden Teilen Ultraschallschwingungen zugeführt, und einincrease in electrical resistance to a significantly smaller cross-section than the legs 7. The metal strip 3, the solder body 2 and the semiconductor body 1 are not detailed in the drawing The means shown are brought into the soldering position on the support table 6. Then the needle 5 lowered and placed on the parts to be connected with light pressure. To carry out the soldering ultrasonic vibrations are fed to the parts to be connected by means of the needle 5, and a

The parts to be connected are heated at least to the eutectic temperature of the soldering body 2 and the semiconductor body 1. However, the melting points of the individual materials are not reached. The ultrasonic vibrations only act as a wetting aid during the connection process.
