The sensors are mounted on a metal angle or prism support (8) and attached to corresponding contact pins (2) via an automatic bonding process.Pref. the contact pins (2) have bonding pads (9) at an angle of 45 degrees to the surface of the base plate coupled via wires (7) to bonding pads (9) for the sensors.

Description

Die Erfindung betrifft die Kontaktierung und Verkapselung von integrier­ ten Schaltungsmodulen, insbesondere Sensoren, deren Hauptachsen ein Win­ kel zueinander im Raum aufweisen, sogenannte dreidimensionale Hybride.The invention relates to the contacting and encapsulation of integrier circuit modules, in particular sensors, whose main axes are a win have angles to each other in space, so-called three-dimensional hybrids.

Die Sensoren und ihre Signalverarbeitungs- und Auswerteschaltung sind dabei auf einem Chip integriert und in jeweils einem separaten Gehäuse untergebracht, vgl. die deutsche Patentschrift 37 36 294, Fig. 3 bis 5. Solche Sensorsysteme sind nicht nur aufwendig in der Herstellung sondern sie müssen wegen der hohen Anforderungen, insbesondere in Sicherheitssy­ stemen in Fahrzeugen, hohen Ansprüchen an die Zuverlässigkeit genügen.The sensors and their signal processing and evaluation circuit are integrated on a chip and each housed in a separate housing, cf. the German patent 37 36 294, Fig. 3 to 5. Such sensor systems are not only complex to manufacture but they must meet high demands on reliability because of the high demands, especially in safety systems in vehicles.

Die Erfindung baut auf der vorgenannten Patentschrift auf und möchte ei­ nerseits die Zuverlässigkeit solcher Meßwerterfassungs- oder Sensormodu­ le erhöhen, andererseits mit einem geringeren Fertigungsaufwand auskom­ men. Hierzu gehört ein raumsparendes und ein sicheres automatisierbares Kontaktieren und Verpacken.The invention is based on the aforementioned patent specification and would like egg on the other hand, the reliability of such measured value acquisition or sensor modules increase le, on the other hand get along with a lower manufacturing effort men. This includes a space-saving and a safe, automatable one Contact and pack.

Die Lösung der Erfindung ist in Anspruch 1 enthalten. Aus- und Weiter­ bildungen der Erfindung sind weiteren Ansprüchen sowie der Beschreibung und Zeichnung eines Ausführungsbeispiels entnehmbar.The solution of the invention is contained in claim 1. Off and on Formations of the invention are further claims and the description and drawing of an embodiment can be removed.

Die wesentlichsten Vorteile der erfindungsgemäßen Lösung bestehen darin, daß die Sensoren mit ihren Hauptachsen - hier Hauptempfindlichkeitsach­ sen (A1, A2) - in einer gewünschten (Fahrt-)Richtung im Raum eines Fahr­ zeuges als Hybrid-IC′s in einem Gehäuse unterbringbar sind und zugleich mit der Verpackung alle Kontaktierungen, insbesondere durch automati­ sches Bonden, vornehmbar sind. Diese Kontaktierungen werden bei der Er­ findung dadurch besonders erleichtert, daß die Bondflecken der Pins und die Sensormodule parallel zueinander angeordnet sind in dem gewählten Winkel im Raum bzw. 90° hierzu - vgl. die Zeichnung, die zwecks Be­ schreibung eines Ausführungsbeispieles beigefügt ist, ohne daß die Er­ findung hierauf beschränkt ist. The main advantages of the solution according to the invention are that the sensors with their main axes - here main sensitivity sen (A1, A2) - in a desired (driving) direction in the space of a driving stuff as a hybrid IC’s can be accommodated in one housing and at the same time with the packaging all contacts, especially by automati chemical bonding, can be performed. These contacts are made with the Er invention is particularly relieved that the bond spots of the pins and the sensor modules are arranged parallel to each other in the selected one Angle in space or 90 ° to this - cf. the drawing, for the purpose of loading writing an embodiment is attached without the Er finding is limited to this.  

Fig. 1 zeigt einen Querschnitt durch das Gehäuse für die IC-Hybride und Fig. 1 shows a cross section through the housing for the IC hybrids and

Fig. 2 zeigt den um seine 45° geneigte Mittelachse drehbaren Arbeits­ tisch für das Bonden. Fig. 2 shows the rotatable about its 45 ° central axis work table for bonding.

Die Fig. 1 zeigt in Einbaulage zur Fahrtrichtung den prinzipiellen Auf­ bau des gemeinsamen Gehäuses für die IC-Hybride 4, 5, wobei eine Grund­ platte 1, mit Pins 2 durchsetzt ist, insbesondere solche mit Glasdurch­ führungen 10, wie sie in der integrierten Schaltungstechnik und in der Hybridtechnik üblich sind und leicht kontaktierbar sind, insbesondere durch Drahtbonden. Vor dem Einsetzen der Pins 2 in die Grundplatte 1 sind die Pins an ihren in der Zeichnung oberen Enden 3 abgekröpft um ei­ nen vorgebbaren Winkel, im Beispiel 45°, und ergeben so parallele Bond­ flächen zu den Sensoren in Raumrichtung 1 und zu den Sensoren (4, 5) in Richtung von deren Achsen A1 und A2. Hier sind diese im Ausführungsbei­ spiel 90° zueinander ausgerichtet und gegenüber dem Substrat oder der Grundplatte mit 45°. Diese Winkel können bei Bedarf je nach Anwendungs­ fall auch hiervon abweichend gewählt werden. Die Sensoren 4, 5, welche zu den abgekröpften Enden 3 der Pins 2 parallel angeordnet sind, lassen sich bei der Erfindung in einem Arbeitsgang automatisch bonden. Dabei werden dünne Bonddrähte 7 von den IC-Hybriden mit den Sensoren 4, 5 auf ihren IC-Trägern B mit den Enden 3 der Pins 2 durch automatisches Bonden an den Bondflecken 9 verbunden. Fig. 1 shows in the installation position to the direction of travel the basic construction of the common housing for the IC hybrids 4 , 5 , with a base plate 1 , with pins 2 interspersed, especially those with glass bushings 10 , as they are in integrated circuit technology and are common in hybrid technology and are easy to contact, especially by wire bonding. Before inserting the pins 2 into the base plate 1 , the pins are bent at their upper ends 3 in the drawing by a predeterminable angle, in the example 45 °, and thus result in parallel bonding surfaces to the sensors in spatial direction 1 and to the sensors ( 4 , 5 ) in the direction of their axes A1 and A2. Here these are aligned in the exemplary embodiment at 90 ° to one another and at 45 ° with respect to the substrate or the base plate. Depending on the application, these angles can also be selected differently if necessary. The sensors 4 , 5 , which are arranged parallel to the bent ends 3 of the pins 2 , can be bonded automatically in one operation in the invention. In this case, thin bonding wires 7 are connected by the IC hybrids with the sensors 4 , 5 on their IC carriers B to the ends 3 of the pins 2 by automatic bonding on the bonding spots 9 .

Ein sehr wesentlicher Vorteil der Erfindung ist es, daß die Grundplatte 1 absolut eben ist, wenigstens auf der dem Gehäuse 6 zugekehrten Seite. Das Gehäuse, insbesondere ein Rechteckgehäuse, umfaßt nicht nur die Sen­ soren 4 und 5 auf ihren zueinander abgewinkelten IC-Trägern 8 sondern umhüllt auch die Pins 2, hier die abgekröpften oder abgeschrägten oder anderweitig in einem Winkel zur Grundplatte 1 angeordneten Enden 3 der Pins 2. Die absolut ebene Oberseite der Grundplatte 1 hat den Vorteil, daß hiermit eine absolut dichte Verbindung von Gehäuse und Grundplatte leicht und automatisch herstellbar ist. Die IC-Träger 8 können einfache Bleche sein, die auf der Grundplatte 1 aufgelötet, aufgeschweißt oder ähnlich fest verbunden werden unter dem gewählten Winkel. A very important advantage of the invention is that the base plate 1 is absolutely flat, at least on the side facing the housing 6 . The housing, in particular a rectangular housing, not only includes the sensors 4 and 5 on their angled IC carriers 8 but also envelops the pins 2 , here the bent or beveled or otherwise arranged at an angle to the base plate 1 ends 3 of the pins 2 . The absolutely flat top of the base plate 1 has the advantage that an absolutely tight connection between the housing and the base plate can be produced easily and automatically. The IC carrier 8 can be simple sheets which are soldered, welded or similarly firmly connected to the base plate 1 at the selected angle.

Ein weiterer Vorteil der Erfindung ist in Fig. 2 ersichtlich, die das automatische Bonden mit Hilfe eines Roboters darstellt.Another advantage of the invention can be seen in FIG. 2, which shows automatic bonding with the aid of a robot.

Dabei ist die Grundplatte 1 mit den IC-Hybriden 4, 5 auf ihren Trägern 8 auf dem Drehtisch 11 aufgespannt. Dieser ist ggf. auch um 45° kippbar. Die in Fig. 2 gezeigte Schräglage des Tisches 11 ist die bevorzugte Ar­ beitsstellung für das Bonden. Hier ist nur senkrechtes Bewegen des Bond­ werkzeuges 12 nötig um mittels Druck und Wärme die Drähte 7 mit den vor­ her parallel zueinander aufgebrachten Bondflecken 9 zu verbinden - wie dargestellt. Das Werkzeug 12 braucht hierbei auch nur um einen vorbe­ stimmten Abstand in der vorbestimmten Richtung (zu 14) bewegt zu werden, obwohl der Roboterkopf 13 auch Schwenken und Horizontalbewegung gestat­ tet.The base plate 1 with the IC hybrids 4 , 5 is clamped on their supports 8 on the turntable 11 . This can also be tilted by 45 ° if necessary. The inclined position of the table 11 shown in FIG. 2 is the preferred working position for the bonding. Here, only vertical movement of the bond tool 12 is necessary in order to connect the wires 7 to the bond spots 9 applied in parallel to one another by means of pressure and heat - as shown. The tool 12 only needs to be moved by a predetermined distance in the predetermined direction (to 14 ), although the robot head 13 also allows pivoting and horizontal movement.

Eine Anwendung der Erfindung ist bei Beschleunigungssensoren gegeben, wie sie in der eingangs genannten deutschen Patentschrift erwähnt ist.One application of the invention is in acceleration sensors, as described in the German patent mentioned at the beginning is mentioned.
