Für die modellhafte Beschreibung des Drahtbondvorganges in Abhängigkeit von den Bondparametern ist sowohl das Verständnis der werkstoffwissenschaftlichen Zusammenhänge am Interface als auch im Bonddraht von entscheidender Bedeutung. Diese Vorgänge sind sehr eng mit der Oberflächenaktivierung der Fügepartner und der Drahtdeformation in z-Richtung verknüpft. Während der Bondzeit bildet sich am Interface eine intermetallische Phase vom Typ Au8Al3 aus, deren Schichtdicke von der Höhe der Ultraschallenergie beeinflusst wird. Am Ende des Bondprozesses ist das Interface nahezu vollständig mit intermetallischer Phase bedeckt. Entgegen der bisherigen Vorstellungen wird jedoch die Flash-Au-Schicht der Leiterplattenmetallisierung durch die Relativbewe...
