Abstract
Description
Die Erfindung richtet sich auf ein Verfahren zur Erstellung einer Leiter struktur auf einem platten- oder folienförmigen, isolierenden Träger.The invention is directed to a method for creating a ladder structure on a plate or foil-shaped, insulating support.
Derartige Leiterstrukturen werden für unterschiedliche Anwendungszwecke benötigt. Beispielsweise werden leitende Metallstrukturen auf als Träger fungierenden Glasplatten zur Erstellung sogenannter LCDs benötigt. Weiter hin werden Leiterstrukturen der in Betracht stehenden Art bei Folientas taturen eingesetzt, wo sie zur Ausbildung der Kontakte und Zuleitungen dienen, und wobei zwei mit derartigen Leiterstrukturen versehene Folien durch eine Abstandshalteeinrichtung so im Abstand voneinander gehalten werden, daß die Kontakte nur dann und nur dort geschlossen werden, wo auf die Folien ein mechanischer Druck ausgeübt wird.Such conductor structures are used for different purposes needed. For example, conductive metal structures are used as a carrier Acting glass plates needed to create so-called LCDs. Next towards lead structures of the type under consideration in film tapes tatures used where they are used to train the contacts and supply lines serve, and wherein two foils provided with such conductor structures held at a distance from each other by a spacer be that the contacts are closed only where and on the foils are subjected to mechanical pressure.
Herkömmlicherweise werden die Leiterstrukturen auf die jeweiligen Träger aufgedruckt. Derartige Herstellungsverfahren sind aufwendig und führen dazu, daß Folientastaturen beispielsweise relativ teuer sind.Conventionally, the conductor structures are on the respective carrier printed on. Such manufacturing processes are complex and lead that membrane keyboards, for example, are relatively expensive.
Zur Herstellung von gedruckten Schaltungen ist es an ich auch schon be kannt, eine isolierende Trägerplatte mit einer Kupferschicht zu versehen und die Kupferschicht an nicht von einem Schutzlack bedeckten Stellen in einem Säurebad abzutragen. Die aufgebrachte Schutzlackstruktur muß der später herzustellenden Leiterstruktur entsprechen. Dieses Verfahren ist aber auf solche Trägermaterialien beschränkt, welche von der Säure nicht angegriffen werden und es erfordert die Entsorgung der beim Prozeß an fallenden umweltfeindlichen Reste.For the production of printed circuits it is already on me knows to provide an insulating carrier plate with a copper layer and the copper layer in places not covered by a protective lacquer in to remove an acid bath. The protective lacquer structure applied must correspond to the conductor structure to be produced later. This procedure is but limited to those carrier materials which are not acidic be attacked and it requires the disposal of the process falling environmentally hostile remains.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren anzugeben, welches die präzise und gleichermaßen kostengünstige Herstel lung von Leiterstrukturen auf einem isolierenden Träger ermöglicht.Proceeding from this, the object of the invention is a method specify which is the most precise and equally inexpensive manufacturer development of conductor structures on an insulating support.
Diese Aufgabe wird dadurch gelöst, daß der Träger flächig mit einer lei tenden Beschichtung versehen wird, und daß mittels eines scannerartig verfahrenen Werkzeugs leitendes Material derart abgetragen wird, daß die gewünschte Leiterstruktur verbleibt.This object is achieved in that the carrier with a lei tenden coating is provided, and that by means of a scanner moved tool conductive material is removed so that the Desired conductor structure remains.
Durch die entsprechende Auswahl des Werkzeugs kann sichergestellt werden, daß zwar einerseits die leitende Schicht an den Stellen, die nicht als Leiterbahnen verbleiben sollen, zuverlässig abgetragen wird, daß anderer seits aber auch der Träger unbeschädigt bleibt. Bei diesem Verfahren ist es auch möglich, die Leiterbahnen relativ breit auszubilden, so daß eine gute Leitfähigkeit und eine zuverlässige Kontaktierung erreicht werden.The appropriate selection of the tool can ensure that on the one hand the conductive layer at the points that are not considered Conductors should remain, is reliably removed that others but also the carrier remains undamaged. In this procedure is it is also possible to form the conductor tracks relatively wide, so that a good conductivity and reliable contacting can be achieved.
Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens ist vorgesehen, daß als Werkzeug ein Laserstrahl verwendet wird, der mittels eines handelsüblichen Laserdruckers scannerartig verfahren und angesteuert wird. Dies bedeutet, daß der Laserstrahl z. B. mäanderförmig über die Trägerfläche gefahren wird und nur dort arbeitet und dementsprechend die leitende Beschichtung abträgt, wo keine Leiterstrukturen verbleiben sollen. In a preferred embodiment of the method according to the invention provided that a laser beam is used as a tool, which means of a commercially available laser printer is operated and controlled in a scanner-like manner becomes. This means that the laser beam z. B. meandering over the Carrier surface is driven and only works there and accordingly conductive coating removes where no conductor structures remain should.
Es ist auf diese Weise mit besonderem Vorteil möglich, metallisch be schichtete Trägerfolien, z. B. Polyesterfolien mit Aluminiumbeschichtungen zu verwenden, die handelsüblich sind, weil sie auch für andere Einsatz zwecke Verwendung finden, und welche dementsprechend besonders kostengün stig verfügbar sind. Die Erfindung umfaßt also gerade auch das Bearbeiten handelsüblicher, bereits beschichteter Trägerfolien.It is particularly advantageous in this way to be metallic layered carrier films, e.g. B. polyester films with aluminum coatings to use that are commercially available because they are also used for other purposes find uses, and which accordingly are particularly inexpensive are always available. So the invention includes editing commercially available, already coated carrier films.
In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß mittels des auf höhere Leistung geschalteten Lasers ein folienartiger Träger zu geschnitten wird. Dies bedeutet, daß mit Hilfe des Lasers auch die Außen konturen und eventuelle Ausnehmungen der Trägerfolie erstellt werden kön nen.In a further embodiment of the invention it can be provided that of the laser switched to higher power to a film-like carrier is cut. This means that with the help of the laser also the outside contours and possible recesses of the carrier film can be created nen.
Statt eines Lasers ist es auch denkbar, als Werkzeug ein Feinsandstrahl gebläse oder aber auch ein fräsend arbeitendes Werkzeug zu verwenden. Unter einem fräsend arbeitenden Werkzeug werden dabei Werkzeuge verstan den, welche eine rotierende oder eine hin- und hergehende Bewegung ausfüh ren und mittels eines entsprechenden Fräs- oder Radierelements die leiten de Beschichtung mechanisch abtragen. Dementsprechend ist es ebenso wie mit Hilfe eines Feinsandstrahlgebläses möglich, auch relativ komplizierte Strukturen sauber herauszuarbeiten. Zum Verfahren dieser Werkzeuge kann auf kommerziell verfügbare und erprobte Scanningeinrichtung zurückgegrif fen werden, wie sie z. B. von Plottern bekannt sind.Instead of a laser, it is also conceivable to use a fine sand jet as a tool blower or a milling tool. Tools are understood to mean a milling tool the one that performs a rotating or a reciprocating motion ren and lead with an appropriate milling or erasing element Remove the coating mechanically. Accordingly, it is the same as with Possible with the help of a fine sandblast blower, also relatively complicated Working out structures cleanly. To move these tools can access to commercially available and proven scanning equipment fen as z. B. are known from plotters.
Zur Erzielung einer Korrosionsfestigkeit kann vorgesehen sein, daß auf freiliegende Leiterabschnitte eine Kontaktfett-, Silikon-Schicht od. dgl. aufgetragen wird. Dies ist z. B. bei Folientastaturen bei solchen als An schlußbereich dienenden Leiterabschnitten von Bedeutung, welche nicht durch die jeweils andere Folie abgedeckt sind.To achieve corrosion resistance, it can be provided that exposed conductor sections a contact grease, silicone layer or the like. is applied. This is e.g. B. with membrane keyboards in such as An conductor sections serving in the final area, which are not are covered by the other film.
Neben der Verwendung handelsüblicher, bereits beschichteter Träger kann vorgesehen sein, daß die Herstellung der Beschichtung auf dem Träger durch Kalandrieren, Tauchen, Aufsprühen, Vakuum-Aufdampfen, Sputtern oder Ka schieren erfolgt.In addition to the use of commercially available, already coated supports be provided that the production of the coating on the carrier by Calendering, dipping, spraying, vacuum evaporation, sputtering or Ka sheer takes place.
Die Erfindung richtet sich auch auf die Verwendung des vorstehend be schriebenen Verfahrens speziell zur Herstellung von Leiterstrukturen auf Folien für Folientastaturen für Rechner, Schreibmaschinen und dgl.The invention is also directed to the use of the above described method specifically for the production of conductor structures Films for membrane keyboards for computers, typewriters and the like.
