finierte Mengen an Lot aufbringen zu können. Dieses Verfahren ist Jedoch umständlich, und teuer.to be able to apply defined amounts of solder. This method However, it is cumbersome and expensive.
Der Erfindung liegt die Aufgabe zugrunde, ein vereinfachtes Verfahren der eingangs genannten Art zu entwickeln.The invention is based on the object of developing a simplified method of the type mentioned at the beginning.
Erfindungsgemaß wird diese Aufgabe dadurch gelöst, daß die in die metallischen Anschlußkontakte auslaufenden Teile der Leiterbahnen der gedruckten Schaltung in der Nähe dieser Anschlußkontakte als verengte Stege ausgebildet werden und daß zum Aufbringen des Lotes auf die mit Lot benetzbaren Oberflächenbereiche der gedruckten Schaltung das diese Schaltung tragende Substrat mindestens an der die gedruckte Schaltung tragenden Oberflächenseite mit flüssigem Weichlot in Berührung gebracht wird. Die Anschlußkontakte der gedruckten Schaltung werden dabei gleichmäßig mit Weichlot belegt, so daß sich das Aufbringen einer Glasschicht erübrigt. Die Einsparung dieses Arbeitsganges bringt eine Senkung der Herstellungskosten der mit Lot belegten gedruckten Schaltung um 25 bis 5o% mit sich. Die in die metallischen Anschlußkontakte auslaufenden Teile der Leiterbahnen der gedruckten Schaltung können auch als mehrere parallel zueinander verlaufende Stege ausgebildet werden. Zweckmäßig wird dabei das flüssige Lot auf die mit Lot benetzbaren Oberflächenbereiche der gedruckten Schaltung im Schwallverfahren aufgebracht. Dabei ist es besonders vorteilhaft, wenn das flüssige Lot in einer reduzierenden Schutzgasatmosphäre aufgebracht wird und wenn die gedruckte Schaltung vor dem Aufbringen des flüssigen Lotes in einer reduzierenden Schutzgasatmosphäre erwärmt wird. Nach dem Aufbringen des Lotes auf die mit Lot benetzbaren Oberflächenbereiche der gedruckten Schaltung können die Anschlußkontakte des Halbleiterkörpers mit den mit Weichlot belegten Anschlußkontakten der gedruckten Schaltung in Berührung gebracht werden und dann die so aneinandergefügten Teile desAccording to the invention this object is achieved in that the parts of the conductor tracks of the printed circuit which run out into the metallic connection contacts are designed as narrowed webs in the vicinity of these connection contacts and that the substrate carrying this circuit is used to apply the solder to the surface areas of the printed circuit that can be wetted with solder is brought into contact with liquid soft solder at least on the surface side carrying the printed circuit. The connection contacts of the printed circuit are evenly covered with soft solder, so that the application of a glass layer is unnecessary. The saving of this operation brings a reduction in the production costs of the printed circuit covered with solder by 25 to 50% . The parts of the conductor tracks of the printed circuit which run out into the metallic connection contacts can also be designed as several webs running parallel to one another. In this case, the liquid solder is expediently applied to the surface areas of the printed circuit that can be wetted with solder using a surge process. It is particularly advantageous if the liquid solder is applied in a reducing protective gas atmosphere and if the printed circuit is heated in a reducing protective gas atmosphere before the liquid solder is applied. After the solder has been applied to the surface areas of the printed circuit which can be wetted with solder, the connection contacts of the semiconductor body can be brought into contact with the connection contacts of the printed circuit covered with soft solder and then the parts of the so joined together
