Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer räumlichen, wenigstens in einem Teilbereich gekrümmten Leiterplatte sowie eine nach diesem Verfahren hergestellte Leiterplatte, die eine Grundplatte aus Verstärkungsfasern enthaltendem Epoxydharz aufweist, die mit einer Leiterbahnstruktur versehen ist.The The invention relates to a method for producing a spatial, at least in a partial area curved circuit board and a Printed circuit board produced by this method, which is a base plate made of reinforcing fibers containing epoxy resin, which provided with a conductor track structure is.
Bekannte
Leiterplatten sind als ebene Platten ausgebildet. Sollen räumliche
Leiterbahnstrukturen realisiert werden, die auch gekrümmte Bereiche enthalten,
so werden diese nach dem z.B. aus der
Eine Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zur Herstellung einer räumlichen, wenigstens in ei nem Teilbereich gekrümmten Leiterplatte aufzuzeigen, durch das entsprechende Leiterplatten in einfacher und kostengünstiger Weise realisiert werden können.A The object of the present invention is a method for the production of a spatial, show at least in a subarea curved circuit board, through the corresponding circuit boards in a simpler and more cost-effective Way can be realized.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Anspruchs 1 oder durch eine Leiterplatte mit den Merkmalen des Anspruchs 10 gelöst.These The object is achieved by a Method with the features of claim 1 or by a printed circuit board solved with the features of claim 10.
Der Vorteil der erfindungsgemäßen Lösung besteht insbesondere darin, dass dünne Leiterplatten mit praktisch beliebiger räumlicher Gestalt in einfacher und kostengünstiger Weise geschaffen werden können, ohne dass ein Spritzgießwerkzeug erforderlich wäre. Durch die Aushärtung der zunächst biegeschlaffen Grundplatte kann die in diesem Zustand geformte Grundplatte in ihrer Gestalt fixiert werden und bildet eine stabile Raumform. Die Leiterbahnstruktur kann dabei vor oder nach der Formanpassung an eine Form aufgebracht werden und haftet dabei an der im nicht ausgehärteten Zustand noch klebrigen Grundplatte.Of the Advantage of the solution according to the invention exists especially in that thin Circuit boards with virtually any spatial shape in a simple and cheaper Way can be created without an injection mold would be required. By curing the first pliable base plate can be shaped in this state base plate be fixed in their shape and forms a stable spatial form. The conductor track structure can be before or after the shape adaptation be applied to a mold and it does not adhere to the im cured Condition still sticky base plate.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Verfahrens möglich.By in the subclaims listed activities are advantageous developments and improvements of the claim 1 specified method possible.
Zweckmäßigerweise wird zwischen der Form und der biegeschlaffen Grundplatte eine Trennschicht angeordnet, die vorzugswei se als Teflonschicht oder Trennmittelfolie ausgebildet sein kann. Dies erleichtert das Ablösen der Grundplatte von der Form nach der Aushärtung.Conveniently, becomes a separating layer between the mold and the pliable base plate arranged, the vorzugswei se as Teflon or release film can be trained. This facilitates the detachment of the base plate from the mold after curing.
Um die gewünschte Raumform der Leiterplatte reproduzierbar zu erhalten, wird die auf die Form aufgelegte Grundplatte mittels einer Gegenform verpresst, bevor sie erwärmt wird. Dies sichert nicht nur die formgenaue Anpassung an die Form, sondern gewährleistet auch, dass die Gestalt beim Erwärmen beziehungsweise Aushärten erhalten bleibt.Around the desired Room shape of the circuit board reproducible to get the on pressed the mold base plate by means of a counter-mold, before it warms up becomes. This not only ensures the exact fit to the shape, but also guaranteed also, that the shape when heated or curing preserved.
Die Leiterbahnstruktur wird zweckmäßigerweise durch Laserschneiden, Ausätzen oder Ausstanzen aus einer Metallfolie, insbesondere Kupferfolie, hergestellt.The Track structure is expediently by laser cutting, etching or punching out of a metal foil, in particular copper foil, produced.
Zum Aufbringen der so hergestellten Leiterbahnstruktur wird wird diese in einer ersten Ausgestaltung des Verfahrens auf einer Trägerfolie oder folienartigen Trägerplatte angeordnet und damit auf die noch nicht ausgehärtete Grundplatte aufgebracht. Danach wird die Trägerfolie oder Trägerplatte abgezogen.To the Applying the conductor track structure thus produced will become this in a first embodiment of the method on a carrier film or foil-like carrier plate arranged and thus applied to the not yet cured base plate. After that becomes the carrier film or support plate deducted.
In einer zweiten Ausgestaltung des Verfahrens wird die Leiterbahnstruktur auf eine weitere biegeschlaffe, noch nicht ausgehärtete Platte oder auf eine ausgehärtete, aber verformbar dünne Platte aufgebracht und damit auf die noch nicht ausgehärtete Grundplatte aufgebracht. Die beiden noch nicht ausgehärteten Platten verbinden sich dadurch in vorteilhafter Weise besonders innig.In A second embodiment of the method is the conductor track structure on another pliable, not yet cured plate or on a hardened, but deformable thin Applied plate and thus on the not yet hardened base plate applied. The two not yet cured plates connect characterized in an advantageous manner particularly intimately.
In einer dritten Ausgestaltung des Verfahrens wird die Leiterbahnstruktur mittels einer wenigstens einen Saugarm oder -greifer aufweisenden Handhabungsvorrichtung auf die noch nicht ausgehärtete Grundplatte aufgebracht. Bei dieser Verfahrensversion kann die Leiterbahnstruktur direkt aufgebracht werden und muss nicht vorher noch mit einem Hilfsmedium versehen werden.In A third embodiment of the method becomes the conductor track structure by means of a handling device having at least one suction arm or gripper on the not yet cured Base plate applied. In this process version, the conductor track structure be applied directly and does not have to be done before with an auxiliary medium be provided.
Zweckmäßigerweise wird die Leiterbahnstruktur vor dem Aufbringen mit einer auf der Haftseite rauen oder aufgerauten Oberfläche versehen, um eine gute Haftung zu gewährleisten.Conveniently, is the conductor track structure before application with a on the adhesive side rough or roughened surface provided to ensure good adhesion.
