Description
Die Erfindung bezieht sich auf ein Verfahren zum Kontaktieren von Leiterbahnanordnungen nach dem Anspruch 1 und auf eine Kontaktanordnung nach dem Anspruch 9.The invention relates to a method for contacting of conductor arrangement according to claim 1 and to one Contact arrangement according to claim 9.
Elektrische und elektronische Schaltungen weisen Leiterbahnzüge auf, die an Anschluß- oder Kontaktstellen mit äußeren Anschluß verbindungen z. B. in Form von Drähten verbunden werden. Die Anschlußdrähte werden z. B. durch Löten, Ultraschallbonden, Thermokompression oder Spaltelektrodenschweißen an den Kontakt stellen befestigt. Üblich sind auch äußere Anschlußverbindungen durch elektrisch leitende Kleber, beispielsweise Schmelzkleber oder Kleber mit einem Lösungsmittelzusatz.Electrical and electronic circuits have conductor tracks on that at connection or contact points with external connection connections z. B. connected in the form of wires. The Lead wires are z. B. by soldering, ultrasonic bonding, Thermocompression or gap electrode welding to the contact put attached. External connections are also common through electrically conductive adhesives, for example hot melt adhesives or glue with a solvent additive.
Aus der DE-OS 28 31 984 ist eine Kontaktanordnung bekannt, bei der auf einem starren Substrat eine Mehrzahl von räumlich be grenzten Kontaktstellen vorhanden ist, die durch mittels Sieb druck aufgebrachtem, elektrisch leitfähigen Schmelzkleber be deckt sind. Ein flexibles Substrat wird so vorbereitet, daß Kontaktstellen auf diesem hinsichtlich ihrer Lage und Ausrich tung dem jeweiligen Gegenstück auf dem starren Substrat ent sprechen. Um die elektrische und mechanische Verbindung herzu stellen, wird ein erwärmter Stempel auf die mit dem Schmelz kleber versehenen Bereiche abgesenkt, wobei der Schmelzkleber erweicht und anschließend bei Erkalten wieder verfestigt wird. Bei dieser Kontaktanordnung ist nicht auszuschließen, daß bei eng benachbarten Kontaktstellen der leitfähige Schmelzkleber einen Kurzschluß zu benachbarten leitenden Bereichen erzeugt. Die Verbindung ist darüberhinaus bei höheren Temperaturen nicht beständig.A contact arrangement is known from DE-OS 28 31 984, at which on a rigid substrate be a plurality of spatially limited contact points is present, by means of a sieve pressure applied, electrically conductive hot melt adhesive be are covered. A flexible substrate is prepared so that Contact points on this with regard to their location and orientation tion of the respective counterpart on the rigid substrate speak. To establish the electrical and mechanical connection put a heated stamp on the one with the enamel glued areas lowered, the hot melt adhesive softened and then solidified again when cooled. With this contact arrangement it cannot be ruled out that at closely adjacent contact points of the conductive hot melt adhesive creates a short circuit to adjacent conductive areas. Furthermore, the connection is not at higher temperatures resistant.
Aufgabe der Erfindung ist es, ein Verfahren zum Kontaktieren von Leiterbahnanordnungen und eine Kontaktanordnung zu schaf fen, die auch bei miniaturisierten Schaltungen unabhängig vom Leiterbahnmaterial und den Umgebungsbedingungen einen stabilen, insbesondere elektrisch stabilen Kontakt gewährleisten.The object of the invention is a method for contacting of conductor arrangement and a contact arrangement to create fen, even with miniaturized circuits regardless of Conductor material and the environmental conditions a stable, Ensure in particular electrically stable contact.
Erfindungsgemäß wird diese Aufgabe durch die in den Ansprüchen 1 und 9 angegebenen Merkmale gelöst. Das zweite Substrat bildet aufgrund des oder der Durchgangslöcher eine Maske, deren Durch gangsöffnungen mit einer leitfähigen Füllung versehen werden, so daß vorteilhaft in Hinsicht auf eine miniaturisierte Bauweise die elektrische Verbindung an den Kontaktstellen des ersten Substrats lokal im wesentlichen auf die Querschnittsfläche der Durchgangslöcher begrenzt ist. Das Aufbringen der leitfähigen Füllung durch die Maske hat darüberhinaus den Vorteil, daß definierte Mengen der Füllung aufgebracht werden können und so ein Verlaufen der Füllung in die Leiterbahnanordnung ausge schlossen ist. Darüberhinaus ist das Verfahren automatisierbar, so daß große Stückzahlen kostengünstig kontaktiert werden kön nen. Das Material bzw. die Ausbildung des zweiten Substrats kann vollkommen unabhängig von den Gegebenheiten beim ersten Substrat bestimmten Erfordernissen entsprechend gewählt werden; das Substrat kann beispielsweise starr oder flexibel, dick oder dünn sein. Damit wird auch ermöglicht, das Befestigungsverfah ren für die Anschlußdrähte zweckentsprechend zu wählen. Die Leiterbahnanordnung auf dem zweiten Substrat von dem oder den Durchgangslöchern zu einem Anschlußfleck für die Verdrahtung kann aus auf das Befestigungsverfahren abgestimmten Materialien aufgebaut sein, beispielsweise aus Materialien, die besonders geeignet für Lötvorgänge sind.According to the invention this object is achieved by the in the claims 1 and 9 specified features solved. The second substrate forms because of the through hole or holes a mask, the through passage openings are provided with a conductive filling, so advantageous in terms of miniaturized construction the electrical connection at the contact points of the first Local substrate essentially on the cross-sectional area of the Through holes are limited. Applying the conductive Filling through the mask also has the advantage that defined amounts of the filling can be applied and so a running of the filling in the conductor arrangement is closed. In addition, the process can be automated, so that large quantities can be contacted inexpensively nen. The material or the formation of the second substrate can be completely independent of the circumstances at the first Substrate selected according to specific needs; for example, the substrate can be rigid or flexible, thick or be thin. This also enables the fastening method ren to choose appropriately for the connecting wires. The Circuit arrangement on the second substrate of the or Through holes to a connection pad for the wiring can be made from materials matched to the fastening method be built up, for example from materials that are special are suitable for soldering processes.
Eine bevorzugte Variante des erfindungsgemäßen Verfahrens sieht vor, daß die Füllung des oder der Durchgangslöcher so vorgenom men wird, daß Teile der Anschlußbereiche auf der dem ersten Substrat abgewandten Oberfläche des zweiten Substrats in einen Bereich, der größer ist als der durch den Querschnitt der Durchgangslöcher definierte, von dem Füllmaterial überdeckt werden; man erhält so eine mechanisch besonders robuste Aus führung mit einem großflächigen Kontakt auf dem zweiten Sub strat. Bei einer wenig Füllmaterial benötigenden Verfahrens variante ist vorgesehen, daß die Mantelfläche des oder der Durchgangslöcher mit elektrisch leitendem Material beschichtet wird; dies ist besonders vorteilhaft, wenn die Beschichtung im Lauf der Herstellungsprozesse des zweiten Substrats ohne einen separaten Verfahrensschritt mit vorgenommen werden kann. Bei dieser Variante ist eine vollständige Füllung der Durchgangs löcher nicht zwingend erforderlich.A preferred variant of the method according to the invention provides before that the filling of the through holes or so vorgenom men that parts of the connection areas on the first Surface of the second substrate facing away from the substrate into a Area that is larger than that through the cross section of the Through holes defined, covered by the filling material become; you get a mechanically particularly robust Aus guidance with a large contact on the second sub strat. With a process requiring little filler material variant is provided that the outer surface of the or Through holes coated with electrically conductive material becomes; this is particularly advantageous if the coating in the Run the manufacturing processes of the second substrate without one separate process step can be made with. At this variant is a complete filling of the passage holes not absolutely necessary.
Die Verwendung eines leitfähigen Klebers hat den Vorteil, daß Leiterbahnen, die wegen ihrer Schichtdicke oder ihres Materials nicht schweißbar oder lötbar sind, ohne weiteres kontaktiert werden können; auf die Abscheidung und Strukturierung lötbarer oder schweißbarer Schichten kann verzichtet werden, was z. B. bei Dünnfilmschaltungen den Gesamtprozeß vereinfacht und ko stengünstiger macht. Die Verwendung leitfähiger Epoxidharze z. B. hat den Vorteil der besseren Temperaturbeständigkeit ge genüber einer weichgelöteten Kontaktanordnung. Das Aushärten des Klebers kann vorteilhaft unterhalb 200° Celsius erfolgen, so daß Substrate aus organischem Material eingesetzt werden können, die vorteilhaft auch als flexible Substrate aus z. B. Polyimid ausgebildet sein können.The use of a conductive adhesive has the advantage that Conductor tracks because of their layer thickness or their material are not weldable or solderable, contacted without further notice can be; on the deposition and structuring solderable or weldable layers can be omitted, which z. B. with thin film circuits, the overall process is simplified and knocked out makes it cheaper. The use of conductive epoxy resins e.g. B. has the advantage of better temperature resistance ge compared to a soft soldered contact arrangement. The curing the adhesive can advantageously take place below 200 ° Celsius, so that substrates made of organic material are used can, which advantageously as flexible substrates made of z. B. Polyimide can be formed.
Bei der erfindungsgemäßen Verwendung eines leitfähigen Klebers wird in vorteilhafter Weise die Leitfähigkeit und die niedrige Aushärtetemperatur genutzt, wozu noch die Klebeigeschaften als zusätzlicher Vorteil hinzukommen.When using a conductive adhesive according to the invention will advantageously the conductivity and the low Hardening temperature used, what the adhesive properties as added advantage.
Insbesondere der Einsatz eines niedrigschmelzenden Lots als Füllmittel hat den Vorteil, daß auf sehr kleinen Lötstellen, nämlich solchen mit einem Durchmesser kleiner als 0,5 mm, defi niert gelötet werden kann, d. h. es können in vorteilhafter Weise kleine Flächen kontaktiert werden, die ohne Anwendung des erfindungsgemäßen Verfahrens nicht mehr lötbar sind.In particular the use of a low melting solder as Filler has the advantage that on very small solder joints, namely those with a diameter smaller than 0.5 mm, defi can be soldered, d. H. it can be more beneficial Way to contact small areas without using the are no longer solderable.
Der Einsatz von leicht zu verarbeitenden Dickschichtpasten ist z. B. dann vorteilhaft, wenn keramische Substrate verwendet werden. The use of easy-to-use thick-film pastes is e.g. B. advantageous if ceramic substrates are used become.
Bildet man eine Kontaktstelle auf dem ersten Substrat länglich aus, so erweist sich die Zuordnung mehrerer Durchgangslöcher zu dieser Kontaktstelle als fertigungstechnisch vorteilhafte, besonders stabile Ausgestaltung.An elongated contact point is formed on the first substrate the assignment of several through holes proves to be this contact point as advantageous in terms of production technology, particularly stable design.
