Bei diesem bekannten Verfahren wird der Kleber auf die Leiterplatte oder das Keramiksubstrat aufgebracht und dann der Chip entsprechend positioniert. Es wird also mit einer Einheit, die vorzugsweise drei Bewegungsfreiheiten besitzt und die einen Stempel aufweist, der Kleber aus dem Vorratsbehälter auf die Leiterplatte aufgebracht. Der Chip wird mit einer in einer Saugnadelhalterung vorgesehenen Saugnadel, die vorzugsweise ebenfalls drei Bewegungsfreiheiten hat, zu der Klebestelle auf der Leiterplatte angeliefert und entsprechend befestigt. Nachteilig bei diesem Verfahren ist es, daß zwei Einheiten oder Kopf maschinen mit jeweils vorzugsweise dreiIt is known that an adhesive is used to fasten electronic circuits, for example chips, on a printed circuit board. In this known method, the adhesive is applied to the circuit board or the ceramic substrate and then the chip is positioned accordingly.

Mit dieser Erfindung ist es erstmals möglich, die Bestückungsgeschwindigkeit weit zu erhöhen. Vor allem ist dies darauf zurückzuführen, daß der Kleber nach der Bereitstellung aus dem Vorratsbehälter, direkt auf einen zur Befestigung vorgesehenen Teil, nämlich auf den Chip, aufgebracht wird.The method according to the invention is characterized in that the adhesive is applied to the chip, the adhesive being distributed on the surface of the chip to be wetted in a defined manner with regard to thickness and application form. With this invention it is possible for the first time to increase the assembly speed considerably.

Auch mit dieser Verfahrensvariante ist eine Verkürzung der Arbeitszeit pro Verklebung möglich. Auch hier entfallen auf Grund der direkten Aufbringung des Klebers auf die zu benetzende Fläche des Chips arbeits- und zeitintensive Zwischenschritte. Die Öffnung des Klebstoff-Spenders kann in einer Nadel, die am Klebstoff-Spender angeordnet ist, vorgesehen werden. Ebenso kann aber auch eine Öffnung eines Srühmechanismus für den Klebstoff nach oben gerichtet sein.According to a further special feature of the invention, this is characterized in that the adhesive required for at least one bond, preferably with pressure, is provided from an adhesive dispenser (dispenser) provided with the opening facing upwards and that the chip which can be transported with a suction needle is positioned for glue transfer and that the chip is then transported to the corresponding position on the circuit board with the suction needle for gluing.

Durch diese Weiterbildung kann die Quantität des Klebers definiert auf der zu benetzenden Fläche des Chips einfach aufgebracht werden. Derartige Muster können beispielsweise entsprechend eines Sterns, einer Schneeflocke, einer Fischgräte oder dergleichen ausgebildet sein.According to a further development of the invention, the chip is moved in a freely defined pattern relative to the opening of the adhesive dispenser in order to distribute the adhesive when the adhesive is taken over, with the volume flow simultaneously a certain, but freely definable, time course is impressed on the adhesive from the opening.

In this case, the suction needle holder can be arranged on a device which, for example, carries out a circular movement. The defined one The adhesive cartridge executes movement for the targeted delivery of the adhesive onto the surface of the chip to be wetted.
Nach einem weiteren besonderen Merkmal der Erfindung ist eine den Chip transportierende Saugnadel vorgesehen ist, die den Chip in einen bevorrateten Kleber taucht und anschließend zur Verklebung auf die entsprechende Position auf der Leiterplatte transportiert. Mit dieser einfachsten Konstruktionsvariante wird vorteilhafterweise die geringste Arbeitszeit erreicht, da praktisch alle Zwischenschritte wegfallen.According to a further special feature of the invention, a suction needle that transports the chip is provided, which dips the chip into a stored adhesive and then transports it to the corresponding position on the printed circuit board for gluing. With this simplest construction variant, the shortest working time is advantageously achieved, since practically all intermediate steps are eliminated.
Gemäß einer Ausgestaltung der Erfindung ist die Saugnadel in einer Saugnadelhalterung gelagert, die der Saugnadel mindestens zwei Bewegungsfreiheiten gewährt. Durch die Bewegungsfreiheit der Saugnadel ist eine Positionierung des Chips auf der Leiterplatte gewährleistet.According to one embodiment of the invention, the suction needle is mounted in a suction needle holder, which grants the suction needle at least two freedom of movement. The freedom of movement of the suction needle ensures that the chip is positioned on the circuit board.
Nach einer besonderen Weiterbildung der Erfindung ist die Saugnadel in einer Saugnadelhalterung gelagert, die der Saugnadel mindestens drei Bewegungsfreiheiten, nämlich in x, y und z-Richtung, gewährt. Je mehr Bewegungsfreiheiten die Saugnadel aufweist, desto qualitativ hochstehender erfolgt die Positionierung des Chip. Es liegt durchaus im Bereich dieser Technik auch Saugnadelhalterungen mit vier Bewegungsfreiheiten, nämlich x, y, z- Richtung und Drehen einzusetzen.According to a special development of the invention, the suction needle is mounted in a suction needle holder, which grants the suction needle at least three freedom of movement, namely in the x, y and z direction. The more freedom of movement the suction needle has, the higher the positioning of the chip will be. It is quite within the scope of this technology to use suction needle holders with four freedom of movement, namely x, y, z direction and turning.
Die Erfindung wird an Hand von Ausführungsbeispielen, die in der Zeichnung dargestellt sind, näher erläutert.The invention is explained in more detail with reference to exemplary embodiments which are shown in the drawing.

The location information selected in the description, e.g. above, below, laterally etc. refer to the immediately described and illustrated figures and are to be transferred to the new position in the event of a change of position. Furthermore, individual features from the exemplary embodiment shown can also represent independent solutions according to the invention.
Gemäß der Fig. 1 bis 3 ist eine Einrichtung zum Befestigen von elektronischen Schaltungen, also insbesondere von sogenannten Chips 1 , auf einer Leiterplatte 2 oder einem Substrat, vorzugsweise Keramiksubstrat, mit einem Kleber 3 in den einzelnen Schritten aufgezeigt.1 to 3, a device for attaching electronic circuits, in particular so-called chips 1, to a circuit board 2 or a substrate, preferably a ceramic substrate, is shown with an adhesive 3 in the individual steps.
Entsprechend der Fig. 1 ist in einer Wanne 4 der Kleber 3 bevorratet. Die Wanne 4 kann als Drehteller ausgebildet sein. Der bevorratete Kleber 3 wird mittels einer Rakel 1 1 in der Wanne 4 kontinuierlich gleichmäßig verteilt, so daß für jede Kleberübernahme eine definierte Menge zur Verfügung steht. Für die Kleberübernahme ist ein Stempel 5 auf einem Arm 6 vorgesehen, der um eine Achse 7 um 180° verschwenkbar ist und der in die Wanne 4 eintaucht und die für eine Verklebung notwendige bzw. definierte Klebermenge aufnimmt. Nach dem Aufnehmen des Klebers 3 wird der Stempel 5 um die Achse 7 um 180° verschwenkt, so daß die Aufnahmefläche des Stempels 5 nach oben weist.1, the adhesive 3 is stored in a tub 4. The tub 4 can be designed as a turntable. The stored adhesive 3 is continuously and uniformly distributed in the tub 4 by means of a squeegee 11, so that a defined amount is available for each adhesive transfer. For the adhesive transfer, a stamp 5 is provided on an arm 6, which can be pivoted through an axis 7 by 180 ° and which dips into the tub 4 and receives the amount of adhesive necessary or defined for bonding. After the adhesive 3 has been picked up, the stamp 5 is pivoted about the axis 7 by 180 °, so that the receiving surface of the stamp 5 points upward.
Der nächste Schritt wird entsprechend der Fig. 2 aufgezeigt. Der zur Verklebung vorgesehene Chip 1 wird mit einer Saugnadel 8, die in einer Saugnadelhalterung 9 angeordnet ist, von der Ablösung von der Folie bis zu seiner Verklebung auf der Leiterplatte 2 transportiert. Der von der Folie abgelöste Chip 1 wird über der mit Kleber 3 versehenen Aufnahmefläche des Stempels 5 mit der Saugnadel 8 positioniert und zur Kleberübernahme mit dem Kleber 3 in Kontakt gebracht. Der mit Kleber 3 versehene Chip 1 wird mit der Saugnadel 8 zur Verklebungsstelle auf der Leiterplatte 2 weitertransportiert.The next step is shown in accordance with FIG. 2. The chip 1 provided for gluing is removed from the film with a suction needle 8, which is arranged in a suction needle holder 9 its glue transported on the circuit board 2. The chip 1 detached from the film is positioned with the suction needle 8 over the receiving surface of the stamp 5 provided with adhesive 3 and brought into contact with the adhesive 3 for the adhesive transfer. The chip 1 provided with adhesive 3 is transported further with the suction needle 8 to the bond point on the printed circuit board 2.
Die Verklebung des Chips 1 auf der Leiterplatte 2 ist entsprechend der Fig. 3 dargestellt. Dabei wird der Chip 1 über der definierten Verklebungsstelle der Leiterplatte 2 positioniert und vorzugsweise durch Absenken des Chips 1 mit der Saugnadel 8, zur Verklebung mit der Leiterplatte 2 gebracht.The bonding of the chip 1 on the printed circuit board 2 is shown in accordance with FIG. 3. In this case, the chip 1 is positioned over the defined bond point of the printed circuit board 2 and is preferably brought to be bonded to the printed circuit board 2 by lowering the chip 1 with the suction needle 8.
Wie bereits in der Beschreibungseinleitung kurz aufgezeigt, liegt der Vorteil dieses Verfahrens und der Einrichtung zur Durchführung des Verfahrens vor allem darin, daß nur eine Saugnadelhalterung 9 in der Anlage Verwendung findet. Die Bereitstellung des Klebers 3 erfolgt über einen Stempel 5 der nur um eine Achse 7 schwenkbar ist. Es wird also in der Transportebene nur eine Saugnadelhalterung 9 bewegt, so daß keine Abstimmungs- oder Koordinationsprobleme gegeben sind. Auch die Schwenkeinrichtung, also der Arm 6 für den Stempel 5 ist sehr einfach im Aufbau und ist auch einfach mit dem Transportweg des Chips 1 zu koordinieren.As already briefly pointed out in the introduction to the description, the advantage of this method and the device for carrying out the method lies primarily in the fact that only one suction needle holder 9 is used in the system. The adhesive 3 is provided via a stamp 5 which can only be pivoted about an axis 7. So only one squeegee holder 9 is moved in the transport plane, so that there are no coordination or coordination problems. The swiveling device, ie the arm 6 for the stamp 5, is also very simple in construction and is also easy to coordinate with the transport path of the chip 1.
Die Saugnadel 8 ist in der Saugnadelhalterung 9 derart gelagert, daß sie mindestens zwei Bewegungsfreiheiten aufweist. Vorzugsweise findet aber eine Saugnadelhalterung 9 Verwendung die der Saugnadel 8 drei Bewegungsfreiheiten, nämlich in x, y und z-Richtung gewährt. Bei speziellen Anlagen sind jedoch Saugnadelhalterungen 9 im Einsatz, die der Saugnadel 8 vier Bewegungsfreiheiten, nämlich die vorher genannten und Drehen, gewährt. Mit einem derartigen Werkzeug sind natürlich hohe Qualitäten und auch Quantitäten in der Fertigung zu erzielen.The suction needle 8 is mounted in the suction needle holder 9 in such a way that it has at least two freedom of movement. Preferably, however, a suction needle holder 9 is used which grants the suction needle 8 three freedom of movement, namely in the x, y and z direction. In special systems, however, suction needle holders 9 are used, which give the suction needle 8 four freedom of movement, namely the aforementioned and turning. With such a tool, of course, high qualities and quantities can be achieved in production.
Ein weiterer Schritt zur Erhöhung der Qualität der Verklebungsstelle ist dadurch zu erreichen, daß der Kleber 3 auf der zu benetzenden Fläche des Chips 1 hinsichtlich Dicke und Auftragsform definiert verteilt wird. Die Definierung der Kleberverteilung kann mit einem Muster, beispielsweise entsprechend einem Stern, einer Schneeflocke oder einer Fischgräte, des Stempels 5 erreicht werden. Die Kleberverteilung über die zu benetzende Chipfläche kann durch besondere Maßnahmen, die natürlich in Richtung Prozeßoptimierung gehen, variiert werden. So kann beispielsweise die Quantität des Klebers 3 vom Bereich des Mittelpunktes der mit Kleber zu benetzenden Fläche des Chips 1 zu den Außenrändern abnehmen.A further step to increase the quality of the bond point can be achieved in that the adhesive 3 on the surface of the chip 1 to be wetted is distributed in a defined manner in terms of thickness and form of application. The definition of the adhesive distribution can be achieved with a pattern, for example corresponding to a star, a snowflake or a fish bone, of the stamp 5. The adhesive distribution over the chip area to be wetted can be varied by special measures, which naturally go in the direction of process optimization. For example, the quantity of the adhesive 3 can decrease from the area of the center of the surface of the chip 1 to be wetted with adhesive to the outer edges.
Eine weitere Ausführungsvariante des Verfahren und auch der Einrichtung zur Durchführung des Verfahrens bei dem der Kleber 3 auf den Chip 1 aufgebracht wird, wird gemäß der Fig. 4 näher erläutert. Dabei wird der für mindestens eine Verklebung notwendige Kleber 3 aus einem mit nach oben gerichteter Öffnung vorgesehenen Klebstoff-Spender 10, einem sogenannten Dispenser, bereitgestellt. In dieser dargestellten Ausführungsvariante ist die Öffnung in einer Nadel des Dispensers vorgesehen. Natürlich könnte auch ein Sprühmechanismus für den Kleber 3 Verwendung finden. Die Bereitstellung kann mit Druck erfolgen. Der mit der Saugnadel 8 transportierbare Chip 1 wird zur Kleberübernahme über der Öffnung des Dispensers 10 positioniert und vorzugsweise zur Kleberübernahme abgesenkt. Anschließend wird der Chip 1 mit der Saugnadel 8, die in der Saugnadelhalterung 9 angeordnet ist, zur Verklebung auf die entsprechende Position auf der Leiterplatte 2 transportiert. Die Verklebung erfolgt im Sinne der Ausführungen zur Fig. 3.A further embodiment variant of the method and also of the device for carrying out the method in which the adhesive 3 is applied to the chip 1 is explained in more detail in accordance with FIG. 4. In this case, the adhesive 3 required for at least one bond is provided from an adhesive dispenser 10, a so-called dispenser, with the opening facing upwards. In this embodiment variant shown, the opening is provided in a needle of the dispenser. Of course, a spray mechanism for the adhesive 3 could also be used. The provision can be made with pressure. The chip 1, which can be transported with the suction needle 8, is positioned above the opening of the dispenser 10 for the adhesive transfer and preferably lowered for the adhesive transfer. The chip 1 is then transported with the suction needle 8, which is arranged in the suction needle holder 9, for gluing to the corresponding position on the printed circuit board 2. The gluing takes place in the sense of the explanations for FIG. 3.
Zur Erzielung des definierten Kleberauftrages auf der zu benetzenden Chipfläche kann sowohl der Chip 1 und/oder auch der Dispenser 10 entsprechend einem Muster verfahren werden. Dem Volumsstrom des Klebers 3 aus der Öffnung des Dispensers 10 kann ein bestimmter, jedoch ein frei wähl- oder definierbarer, Zeitverlauf aufgeprägt sein. Natürlich ist es auch denkbar, daß die Öffnung des Dispensers 10 nach unten gerichtet ist, wobei die Saugnadel 8 den Chip 1 mit nach oben gerichteter Saugnadelspitze transportiert.To achieve the defined adhesive application on the chip surface to be wetted, both the chip 1 and / or the dispenser 10 can be moved according to a pattern. The volume flow of the adhesive 3 from the opening of the dispenser 10 can be stamped with a specific, but freely selectable or definable, time profile. Of course, it is also conceivable that the opening of the dispenser 10 is directed downwards, the suction needle 8 transporting the chip 1 with the suction needle tip pointing upwards.
Weiters ist natürlich auch die einfachste Art des Verfahrens und der entsprechenden Ausführungsform der Einrichtung möglich. Diese ist in Fig. 5 aufgezeigt und wird an Hand dieser Fig. 5 näher erläutert. Dabei wird der Chip 1 mit seiner mit Kleber 3 zu benetzenden Fläche direkt in den in der Wanne 4 vorgesehenen Kleber 3 getaucht. Die den Chip 1 transportierende Saugnadel 8 senkt den Chip 1 direkt in den in der Wanne bevorrateten Kleber 3 und transportiert anschließend den Chip 1 zur Verklebung auf die entsprechende Position auf der Leiterplatte 2. Die Verklebung erfolgt im Sinne der Ausführungen zur Fig. 3.Furthermore, the simplest type of method and the corresponding embodiment of the device are of course also possible. This is shown in FIG. 5 and is explained in more detail with reference to FIG. 5. The chip 1 with its surface to be wetted with adhesive 3 is immersed directly in the adhesive 3 provided in the trough 4. The suction needle 8 transporting the chip 1 lowers the chip 1 directly into the adhesive 3 stored in the tub and then transports the chip 1 for gluing to the corresponding position on the printed circuit board 2. The gluing takes place in the sense of the explanations for FIG. 3.
