Description
Das Einschmelzen von Halbleiteranordnungen in Glasgehäuse erfolgt nach einem bekannten Verfahren mit Hilfe von Wasserstoff-Sauerstoffflammen. Bei diesem bekannten Verfahren besteht jedoch die Gefahr, daß sich Wasserdampf und somit Feuchtigkeit bilden, die die Stabilität der eingescDmolzenen HalbleitLranordnung in Frage stellen.The melting of semiconductor arrangements in glass housings takes place according to a known method with the aid of hydrogen-oxygen flames. at However, this known method there is the risk that water vapor and thus Form moisture, which the stability of the melted semiconductor arrangement to question.
Nach einem anderen Verfahren erfolgt die Einschmelzung durch ringförmig
ausgebildete Heizdrahtwicklungen. Dieses Einschmelzverfahren erfordert einen geringen
Abstand zwischen Heizspule
und Glasgehäuse und bedingt dadurch Abschirmmaßnahmen
zur Verhinderung einer auf das Halbleiterelement einwirkenden Wärmestrahlung. Außerdem
ist es schwierig, eine genaue Bündelung und Konzentration der Wäremstrahlung auf
die Einschmelzstelle zu erzielen. Dieselben Nachteile treten bei einem ähnlichen
Verfahren auf, bei dem anstelle einer Heizspule ein induktiv erhitzter Graphitring
verwendet wird.
Zur Vermeidung dieser Nachteile wird deshalb eine Vorrichtung zum
Einschmelzen von Halbleiteranordnungen in Gehäuse', vorgeschlagen, bei der gemäß
der Neuerung mindestens ein Ultrrotstrah-
Gemäß einer Weiterbildung der Neuerung sind Mittel vorgesehen, durch
die das Gehäuse beim Einschmelzen in Rotation versetzt
Das Einschmelzen erfolgt in einer Einschmelzkammer 13, in der eine Schutzgasatmosphäre aufrechterhalten wird. Das Halbleitergehäuse ist auf eine drehbare Halterung 14 aufgesetzt, die infolge ihrer Rotation bewirkt, daß die zur Einschmelzung erforderliche Erwärmung praktisch gleichzeitig die gesamte Verbindungfläche auf ihrem ganzen Umfang erfaßt.The melting takes place in a melting chamber 13, in which a Protective gas atmosphere is maintained. The semiconductor housing is on a rotatable Mount 14 placed, which, due to its rotation, causes the meltdown required heating practically at the same time on the entire connection surface grasped their full extent.
Es können natürlich gleichzeitig auch mehrere drehbare Halterungen auf einer karusselartigen Vorrichtung angeordnet sein, die in laufender Folge die Halterungen an die Einschmelzstelle gelangen läßt. Das Einschmelzen wird erleichtert, wenn das Halbleitergehäuse aus dunkel gefärbtem Glas besteht, da dieses Schwarzglas die Ultrarot-Strahlung stärker absorbiert.Of course, several rotatable brackets can be used at the same time be arranged on a carousel-like device, the consecutive order Can get brackets to the melting point. Melting down is made easier, if the semiconductor housing is made of dark colored glass, since this is black glass absorbs more infrared radiation.
