Description

Die vorliegende Erfindung betrifft eine Siebdruckvorrichtung mit einem Gewebe und eine in dem Gewebe angeordnete Schablone in Form einer fotolithographisch strukturierten Emulsion. Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer derartigen Siebdruckvorrichtung.The present invention relates to a screen printing device with a fabric and arranged in the fabric template in the form of a photolithographically structured emulsion. The invention further relates to a method for producing such a screen printing device.

Der Siebdruck ist ein Druckverfahren, bei dem eine Druckfarbe oder Druckpaste mit einem messerƤhnlichen Werkzeug, dem Gummirakel (Druckrakel), durch ein feinmaschiges Gewebe hindurch auf das zu bedruckende Material gedruckt wird. Der Siebdruck wird deshalb auch als Durchdruckverfahren bezeichnet. An den Stellen des Gewebes, wo dem Bildmotiv entsprechend keine Farbe gedruckt werden soll, sind die Maschenƶffnungen des Gewebes durch eine an dem Gewebe angeordnete Schablone (z.B. fotolithographisch strukturierte Emulsion) undurchlƤssig fĆ¼r die Druckfarbe oder Druckpaste.Screen printing is a printing process in which an ink or print paste is printed through a fine mesh fabric onto the material to be printed with a knife-like tool, the rubber squeegee. Screen printing is therefore also referred to as a through-printing process. At the locations of the fabric where no color is to be printed according to the image motif, the mesh apertures of the fabric are impermeable to the ink or printing paste by a stencil (e.g., photolithographically structured emulsion) disposed on the fabric.

Neben dem Einsatz im Bereich der Werbung und Beschriftung, im Textil- oder Keramikdruck wird der Siebdruck heute hƤufig auch fĆ¼r das Drucken von Schaltungen im Bereich der Hybridtechnologie, zum Beispiel im Bereich der Mehrlagenkeramiktechnologie verwendet. Ein Beispiel fĆ¼r eine Mehrlagenkeramiktechnologie ist die sogenannte LTCC-Technologie (LTCC = Low Temperature Cofired Ceramics, dt. Niedertemperatur-Einbrand-Keramik), die eine kostengĆ¼nstige Technologie zur Herstellung von Mehrlagenschaltungen auf der Basis von gesinterten KeramiktrƤgern, die in mehreren Lagen Verdrahtungsebenen verbunden durch z-Kontaktierungen, sog. Vias beinhalten, darstellt. Bei der LTCC-Technologie werden die Schaltungselemente mittels Siebdruck auf die GrĆ¼nfolien des spƤteren KeramiktrƤgers aufgebracht, die dann gestapelt und gesintert werden.In addition to advertising and lettering, textiles and ceramics printing, screen printing today is frequently also used for printing circuits in the field of hybrid technology, for example in the field of multilayer ceramic technology. An example of a multilayer ceramic technology is the so-called LTCC (Low Temperature Cofired Ceramics) technology, which is a cost-effective technology for producing multilayer circuits based on sintered ceramic substrates that are interconnected in multiple layers of wiring z-contacts, so-called vias involve represents. In the LTCC technology, the circuit elements are screen printed on the green sheets of the later ceramic support, which are then stacked and sintered.

Die moderne Packaging-Entwicklung fordert heute ungeachtet des Einsatzgebietes das Drucken von feineren Strukturen (Feinstline-Strukturen), um Einbauplatz zu sparen oder um den Verbrauch hochpreisiger Pasten zu minimieren. AuƟerdem fordert die moderne Hochfrequenztechnik in AbhƤngigkeit der Einsatzfrequenz enge Leiterzugbreiten, die auf Basis von Verlusten und gegebenen Impedanzen durch umfangreiche Simulationen vorgegeben werden. Es ist daher wĆ¼nschenswert, feinere Strukturen zu drucken. Zudem kƶnnten, wenn es gelƤnge, feinere Strukturen zu drucken, Mehrlagentechnologie-Prozesse wie LTCC Schaltungen ersetzen, die bisher mittels der DĆ¼nnfilm-Technik hergestellt wurden. Die DĆ¼nnfilm-Technik wird aufgrund ihrer hohen Strukturauflƶsung bisher auf dem Gebiet der Hochfrequenzschaltungen im Hƶchstfrequenz-Bereich verwendet, um HF-taugliche Strukturen zu realisieren. Diese Technik wird durch Abscheidungs- und ƄtzvorgƤnge realisiert. Sie erfordert den Einsatz sehr ebener, vorbehandelter und hochpreisiger Substrate. Zudem ist der DĆ¼nnfilm-Prozess an sich ein kostenintensives Verfahren. DĆ¼nnfilmstrukturen lassen sich auƟerdem nur koplanar auf der SubstratoberflƤche realisieren. Der Einsatz der Mehrlagentechnologie mit Feinstline-Strukturen kƶnnte gegenĆ¼ber der DĆ¼nnfilm-Technik eine deutliche Kostenreduzierung bringen und auƟerdem den Vorteil der Nutzung mehrerer Ebenen u. a. auch fĆ¼r Schirmlagen bieten.Today, regardless of the field of application, modern packaging development demands the printing of finer structures (fine-line structures) in order to save space or to minimize the consumption of high-priced pastes. In addition, the modern high-frequency technology calls depending on the frequency use close Leiterzugbreiten that on Basis of losses and given impedances can be predetermined by extensive simulations. It is therefore desirable to print finer structures. Additionally, if one were able to print finer structures, multi-layer technology processes such as LTCC could replace circuits previously made using thin-film technology. Due to its high structural resolution, the thin-film technique has hitherto been used in the field of high-frequency circuits in the ultra-high frequency range in order to realize structures suitable for HF. This technique is realized by deposition and etching processes. It requires the use of very flat, pretreated and high-priced substrates. In addition, the thin-film process is itself a costly process. In addition, thin-film structures can only be realized coplanar on the substrate surface. The use of multi-layer technology with fine-line structures could bring a significant cost reduction compared to thin-film technology and also offer the advantage of using several levels, including for screen layers.

FĆ¼r den Siebdruck im Bereich der Mehrlagen-Technologie (Dickschichttechnik) sind die Siebdruckrahmen meistens aus Aluminium und werden mit einem Stahlgewebe bespannt, mit dem sich die wƤhrend des Druckvorgangs erforderliche elastische Durchbiegung des Siebes erreichen lƤsst. Eine elastische Durchbiegung des Siebes wƤhrend des Druckvorgangs ist erforderlich fĆ¼r den sogenannten Absprung, d. h. fĆ¼r die zwischen Gewebe und zu bedruckendem Substrat realisierbare Distanz. Zu wenig Absprung kann beispielsweise zur Wolkenbildung im Druck fĆ¼hren, da sich das Gewebe hinter dem Rakel nicht sofort aus dem gedruckten Pastenfilm lƶst - es bleibt in der gedruckten Paste "kleben". Zuviel Absprung erhƶht hingegen die Gewebespannung, was zum einen zu einem Ɯberschreiten der elastischen Dehngrenze des Gewebes fĆ¼hrt und damit zu einem Vorzeitigen Altern des Gewebes, und zum anderen zu unsauberen Ausdrucken aufgrund von Pastenspritzern fĆ¼hren kann, so dass die Schablonenkante kein sauberes Druckbild mehr zeichnen kann.For screen printing in the field of multi-layer technology (thick-film technology), the screen frames are usually made of aluminum and are covered with a steel mesh, which can be achieved during the printing process elastic deflection of the screen. An elastic deflection of the screen during the printing process is required for the so-called bounce, d. H. for the realizable between tissue and substrate to be printed distance. For example, too little jump may lead to cloud formation in the print, since the fabric behind the squeegee does not immediately detach from the printed paste film - it remains "stuck" in the printed paste. Too much bounce, on the other hand, increases tissue tension which, on the one hand, leads to exceeding the elastic yield strength of the tissue and thus leading to premature aging of the fabric and, on the other, impure printouts due to paste spatters, so that the template edge can no longer draw a clean print image ,

Die DrahtstƤrke der verwendeten Gewebe betrƤgt heute etwa zwischen 30 Mikrometern und 16 Mikrometern. Die DurchlƤssigkeit des Gewebes wird durch seine Maschenweite beschrieben, die mittels der sogenannten Mesh-Zahl angegeben wird. Beispielsweise bedeutet 325 Mesh, dass 325 Maschen je Quadratzoll (Quadratinch) vorliegen.The wire thickness of the fabrics used today is approximately between 30 micrometers and 16 micrometers. The permeability of the fabric is described by its mesh size, which is indicated by the so-called mesh number. For example, 325 mesh means that there are 325 stitches per square inch (square inches).

Die Schablone wird hƤufig als Direktschablone mittels eines fotografischen Verfahrens hergestellt. HierfĆ¼r wird das Gewebe mit fotosensitiven Polymeren beschichtet, die mit den gewĆ¼nschten Strukturen belichtet werden. AnschlieƟend werden die belichteten Strukturen entwickelt und die unbelichteten Bereiche ausgewaschen. Das Gewebe, die Schablone (Emulsion) und der Druckrahmen bilden zusammen das Siebdrucksieb.The stencil is often made as a direct stencil by a photographic process. For this purpose, the fabric is coated with photosensitive polymers, which with be exposed to the desired structures. Subsequently, the exposed structures are developed and the unexposed areas are washed out. The fabric, stencil (emulsion) and printing frame together form the screen printing screen.

Beim Drucken wird die Druckpaste auf das Sieb aufgebracht und gleichmƤƟig mittels eines sogenannten Flutrakels auf dem strukturierten Sieb verteilt. AnschlieƟend findet der eigentliche Druckvorgang statt, wobei das Druckrakel mit einer entsprechend angepassten HƤrte Ć¼ber das Sieb gezogen wird. Das Sieb befindet sich bei diesem Druckvorgang in einem bestimmten Abstand von dem zu bedruckenden Substrat, beispielsweise einer LTCC-Folie. Das Sieb wird mittels des Druckrakels elastisch nach unten in Richtung des zu bedruckenden Substrates gedrĆ¼ckt. Gleichzeitig erfolgt mittels des Druckrakels eine Scherung der Druckpaste, die aufgrund ihrer thixotropen Eigenschaft wƤhrend der Scherung ihre ViskositƤt erniedrigt und hierdurch durch die Ɩffnungen des Siebdrucksiebs gepresst werden kann. Nach Beendigung der Scherbeanspruchung weist die Druckpaste wieder die AusgangsviskositƤt auf.During printing, the printing paste is applied to the screen and distributed evenly on the structured screen by means of a so-called flood doctor blade. Subsequently, the actual printing takes place, wherein the squeegee is pulled over the wire with a suitably adjusted hardness. The screen is in this printing at a certain distance from the substrate to be printed, for example, an LTCC film. The screen is pressed by means of the printing doctor down elastically in the direction of the substrate to be printed. At the same time by means of the printing doctor blade, a shear of the printing paste, which reduces its viscosity due to their thixotropic property during the shear and thereby can be pressed through the openings of the screen printing screen. After completion of the shear stress, the printing paste again has the initial viscosity.

Wenn kleinere Auflƶsungen der gedruckten Strukturen (Feinstline-Strukturen) erreicht werden sollen, d. h. eine Auflƶsung unter 50 Mikrometern oder sogar unter 30 Mikrometern, ergibt sich das Problem, dass hierfĆ¼r das Gewebe und die Schablone entsprechend feine Strukturen mit kleinen Ɩffnungen aufweisen mĆ¼ssen und diese feinen Strukturen und kleinen Ɩffnungen in der Schablone und dem Gewebe den Farben- oder Pastenfluss durch das Siebdrucksieb hemmen.If smaller resolutions of the printed structures (fine-line structures) are to be achieved, d. H. For example, if the resolution is less than 50 microns or even less than 30 microns, there is a problem that the fabric and the template must have correspondingly fine structures with small openings and these fine structures and small openings in the template and the fabric through the flow of colors or pastes inhibit the screen printing screen.

In der Druckschrift DE 197 38 873 A1 wird das Problem gelƶst, die Passgenauigkeit beim Siebdrucken zu erhƶhen. AuƟerdem beschƤftigt sich die Druckschrift mit der Frage der Optimierung der DruckqualitƤt bei Feinstrichen und Rastern fĆ¼r Kunststoffgewebe. Die KunststofffƤden des Gewebes sind mit einer aufgedampften oder gesputterten Mantelschicht Ć¼berzogen, die wiederum von einem die Emulsion der Schablone tragenden, durch Galvanisierung entstandenen MetallĆ¼berzug Ć¼berdeckt ist. Die Mantelschicht wird durch einen Bedampfungs- oder Sputter-Prozess mit einer Schichtdicke von etwa 5 Nanometern bis Ć¼ber 200 Nanometern erzeugt. Der Auftrag der Mantelschicht erfolgt mittels galvanischer Abscheidung. Beispielsweise wird eine Kupfer- oder Nickelschicht aufgebracht. Das metallisierte Kunststoffgewebe bewirkt eine hohe reproduzierbare SchablonenqualitƤt mit exzellenter RandschƤrfe und exakter Farbdosierung, da es minimalste Dehnungen bei einer ausreichenden Grundfestigkeit gewƤhrleistet. Somit lƶst das aus dieser Druckschrift bekannte Gewebe das oben angegebene Problem nicht, zumal es sich auf ein Kunststoffgewebe und nicht auf ein Stahlgewebe, das fĆ¼r das Drucken von Schaltungselementen verwendet wird, bezieht. Zudem ist das in der Druckschrift DE 197 38 873 A1 angegebene Herstellungsverfahren fĆ¼r eine Siebdruckvorrichtung sehr aufwƤndig und kostenintensiv.In the publication DE 197 38 873 A1 solves the problem of increasing the accuracy of screen printing. In addition, the publication deals with the question of optimizing the print quality of fine lines and screens for plastic fabrics. The plastic filaments of the fabric are coated with a vapor-deposited or sputtered cladding layer, which in turn is covered by a metal coating which bears the emulsion of the stencil and which has been produced by electroplating. The cladding layer is produced by a sputtering or sputtering process with a layer thickness of about 5 nanometers to over 200 nanometers. The application of the cladding layer by means of electrodeposition. For example, a copper or nickel layer is applied. The metallised plastic fabric results in a high reproducible stencil quality with excellent edge definition and exact ink dosage, as it ensures minimum elongation with sufficient basic strength. Thus, that solves Tissue known from this document does not address the above problem, especially as it relates to a plastic fabric and not to a steel fabric used for printing circuit elements. In addition, this is in the document DE 197 38 873 A1 specified production method for a screen printing device very expensive and costly.

Die EP 1 147 887 A1 offenbart ein Siebdruckplatte zur Auftragung von Beschichtungen auf eine Glasscheibe, insbesondere Scheiben eines Automobils, welche eine ƶlabweisende Beschichtung beidseits des Siebs aufweist. Hier werden groƟflƤchige Beschichtungen durchgefĆ¼hrt. Die genannte Druckplatte ist also fĆ¼r das Drucken feiner Strukturen nicht geeignet.The EP 1 147 887 A1 discloses a screen printing plate for applying coatings to a glass sheet, especially disks of an automobile, which has an oil-repellent coating on both sides of the screen. Here, large-area coatings are carried out. The said printing plate is therefore not suitable for printing fine structures.

Die Druckschrift DE 10 2004 055 113 A1 offenbart ein Verfahren zur Hydrophilierung von SiebdruckschablonentrƤgern, das die Benetzung des SiebdruckschablonentrƤgers mit Schablonenmaterial wesentlich verbessert. Bei der Hydrophilierung des SiebdruckschablonentrƤgers, d. h. des Siebdruckgewebes, wird dieses mit feinstteiligen Oxidteilchen, wie Nanometer-Teilchen aus Metalloxid, bspw. Titanoxid, Aluminiumoxid oder Zirkonoxid, und einem Benetzungsmittel versehen. Als Benetzungsmittel kann beispielsweise ein Tensid verwendet werden. Alternativ hierzu kann das Hydrophilierungsmittel auch bei der Entfernung von Schablonenmaterial von den Siebdruckgewebe eingesetzt werden, vorzugsweise indem es der EntschichtungsflĆ¼ssigkeit zugegeben wird. Bei der Entschichtung des SiebdruckschablonentrƤgers, bei der dieser fĆ¼r die Herstellung eines neuen Siebdrucksiebs mit einer neuen Schablone vorbereitet wird, wird der SiebdruckschablonentrƤger nicht nur von dem Schablonenmaterial befreit, sondern gleichzeitig auch fĆ¼r den nƤchsten Beschichtungsvorgang hydrophiliert. Folglich lƶst auch die in dieser Druckschrift angegebene Beschichtung des Siebdruckgewebes das oben aufgezeigte Problem, feinere Strukturen zu erzeugen, nicht.The publication DE 10 2004 055 113 A1 discloses a method of hydrophilizing screen-printed stencil media which substantially improves the wetting of the stencil stencil sheet with stencil material. In the hydrophilization of the screen printing stencil carrier, ie the screen printing fabric, this is provided with very fine oxide particles, such as nanometer particles of metal oxide, for example. Titanium oxide, alumina or zirconium oxide, and a wetting agent. As the wetting agent, for example, a surfactant can be used. Alternatively, the hydrophilizing agent may also be employed in the removal of stencil material from the screen-printed fabrics, preferably by adding it to the decoating liquid. During the stripping of the screen stencil carrier, during which it is prepared for the production of a new screen printing screen with a new stencil, the screen stencil carrier is not only freed from the stencil material but at the same time hydrophilized for the next coating process. Consequently, the coating of the screen-printed fabric indicated in this publication does not solve the above-indicated problem of producing finer structures.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Siebdruckvorrichtung anzugeben, die das Drucken feinerer Strukturen ermƶglicht. AuƟerdem besteht die Aufgabe der vorliegenden Erfindung darin, ein Verfahren zur Herstellung einer Siebdruckvorrichtung anzugeben, das einfach und kostengĆ¼nstig das Drucken feinerer Strukturen, insbesondere fĆ¼r ein Stahlgewebe, ermƶglicht.The object of the present invention is therefore to provide a screen printing apparatus which enables the printing of finer structures. In addition, the object of the present invention is to provide a method for producing a screen printing device, which allows easy and cost-effective the printing of finer structures, in particular for a steel fabric.

ErfindungsgemƤƟ wird die Aufgabe durch eine Siebdruckvorrichtung gelƶst, bei der das Gewebe und/oder die Schablone jeweils auf der OberflƤche eine das Anhaften einer Siebdruckpaste oder einer Siebdruckfarbe an das Gewebe und/oder an die Schablone vermindernde nanokristallinen Beschichtung aufweist.According to the invention, the object is achieved by a screen printing apparatus in which the fabric and / or the stencil has a nanocrystalline coating which reduces the adhesion of a screen printing paste or a screen printing ink to the fabric and / or to the stencil on the surface.

Durch die angegebene Beschichtung wird erfindungsgemƤƟ die Hemmung des Durchflusses oder Durchtretens der Siebdruckpaste oder der Siebdruckfarbe durch die Gewebemaschen bzw. die Ɩffnungen in der Schablone verringert, sodass ein Gewebe mit einer kleineren Maschenweite bzw. eine Schablone mit kleineren Ɩffnungen verwendet werden kann und hierdurch feinere Strukturen erzeugt werden kƶnnen. Der Effekt des verringerten Anhaftens der Siebdruckpaste oder der Siebdruckfarbe an dem Gewebe bzw. der Schablone wird auch als Lotus-Effekt bezeichnet.The indicated coating, according to the invention, reduces the inhibition of the passage or passage of the screen printing paste or the screen printing ink through the fabric stitches or the openings in the stencil so that a fabric with a smaller mesh size or a stencil with smaller openings can be used and thus finer structures can be generated. The effect of reduced adhesion of the screen printing paste or the screen printing ink to the fabric or stencil is also referred to as the lotus effect.

Besonders einfach wird die Antihaft-Beschichtung mittels einer nanokristallin ausgebildeten Beschichtung, die vorzugsweise Kristalle mit einem Durchmesser von weniger als 10 Nanometern aufweist. Eine derartige Beschichtung hat zudem den Vorteil, dass sie sehr dĆ¼nn aufgetragen werden kann, so dass sie keine wesentliche zusƤtzliche Ƅnderung der Maschenweite oder der Ɩffnungsweite der Schablone bewirkt.The non-stick coating becomes particularly simple by means of a nanocrystalline coating, which preferably has crystals with a diameter of less than 10 nanometers. Such a coating also has the advantage that it can be applied very thin so that it does not cause any significant additional change in the mesh size or the opening width of the template.

Als besonders geeignetes Beschichtungsmaterial fĆ¼r die Beschichtung kann eine Kohlenstoff-Verbindung mit einer diamantƤhnlichen Struktur (DLC) und/oder ein Fluorid und/oder eine fluorbasierte Verbindung, vorzugsweise Teflon (Polytetrafluorethylen, PTFE), und/oder eine siliziumbasierte Verbindung verwendet werden.As a particularly suitable coating material for the coating, a carbon compound having a diamond-like structure (DLC) and / or a fluoride and / or a fluorine-based compound, preferably Teflon (polytetrafluoroethylene, PTFE), and / or a silicon-based compound can be used.

In einem weiteren bevorzugten AusfĆ¼hrungsbeispiel weist die Siebdruckvorrichtung eine Beschichtung mit einer Schichtdicke zwischen etwa 100 nm und etwa einigen Mikrometern auf. Diese Schichtdicken sind einerseits genĆ¼gend dick, um mit einer hohen BestƤndigkeit das leichtere Hindurchtreten der Siebdruckfarbe oder der Siebdruckpaste durch die Gewebemaschen bzw. die Schablonenƶffnungen zu gewƤhrleisten, und erlauben andererseits das Drucken von Feinstline-Strukturen.In a further preferred embodiment, the screen printing device has a coating with a layer thickness between about 100 nm and about a few micrometers. On the one hand, these layer thicknesses are sufficiently thick to ensure with a high degree of stability the easier passage of the screen printing ink or the screen printing paste through the fabric stitches or the stencil openings, and on the other hand permit the printing of fine-line structures.

In einem besonders bevorzugten AusfĆ¼hrungsbeispiel ist die Beschichtung auf der Oberseite des Gewebes und/oder der Schablone, d. h. auf der dem zu bedruckenden Substrat abgewandten Seite des Gewebes und/oder der Schablone, oleophil (hydrophil/-phob, lipophil/-phob) um durch das Anhaften der Paste eine Rollbewegung und damit eine gute Scherung zu erreichen, um den Tixotropieeffekt aufzubauen. Auf der Unterseite des Gewebes und/oder der Schablone, d. h. auf der dem zu bedruckenden Substrat zugewandten Seite des Gewebes und/oder der Schablone, und in den ZwischenrƤumen des Gewebes und der Schablone ist die Beschichtung oleophob ausgebildet, um ein Anhaften/Kleben zu unterdrĆ¼cken. Diese Gestaltung der Siebdruckvorrichtung bewirkt ein sauberes Verteilen der Siebdruckpaste oder der Siebdruckfarbe (Fluten des Siebes) auf der Oberseite und ein gutes Ablƶsen der Siebdruckpaste bzw. der Siebdruckfarbe nach dem Wegfall der durch das Rakel aufgebrachten ScherkrƤfte auf der Unterseite des Siebdrucksiebs.In a particularly preferred embodiment, the coating on the top of the fabric and / or the template, ie on the side facing away from the substrate to be printed on the tissue and / or the template, oleophilic (hydrophilic / -phobic, lipophilic / -phobic) by Sticking the paste a rolling motion and thus a good To achieve shear to build up the Tixotropieeffekt. On the underside of the fabric and / or the stencil, ie on the side of the fabric and / or the stencil facing the substrate to be printed, and in the interstices of the fabric and the stencil, the coating is designed to be oleophobic in order to suppress sticking / sticking , This design of the screen printing device causes a clean distribution of the screen printing paste or screen ink (flooding of the screen) on the top and a good separation of the screen printing paste or the screen printing ink after the elimination of the shear forces applied by the doctor on the underside of the screen printing screen.

Die obige Aufgabe wird auƟerdem durch ein Verfahren zur Herstellung einer Siebdruckvorrichtung gelƶst, bei dem das Gewebe vor dem Aufbringen der Schablone an dem Gewebe und/oder das Gewebe und die Schablone nach dem Aufbringen der Schablone an dem Gewebe jeweils auf der OberflƤche mit einer das Anhaften einer Siebdruckpaste oder einer Siebdruckfarbe an das Gewebe oder an der Schablone vermindernde Beschichtung versehen wird.The above object is also achieved by a method of manufacturing a screen printing apparatus in which the fabric is adhered to the fabric prior to applying the template to the fabric and / or the fabric and the template is applied to the fabric after application of the template to the fabric a screen printing paste or a screen printing ink to the fabric or stencil-reducing coating is provided.

Das erfindungsgemƤƟe Verfahren bewirkt sehr einfach und kostengĆ¼nstig, das Gewebe mit kleinerer Maschenweite bzw. Schablonen mit kleineren Ɩffnungen verwendet werden kƶnnen und ermƶglicht hierdurch den Druck feinerer Strukturen. Das erfindungsgemƤƟe Verfahren beinhaltet hierfĆ¼r lediglich einen einzigen zusƤtzlichen Beschichtungsschritt. Das bekannte Verfahren zur Herstellung einer SiebdrĆ¼ckvorrichtung wird dadurch nicht wesentlich verteuert bzw. verkompliziert.The inventive method causes very simple and inexpensive, the tissue can be used with smaller mesh size or templates with smaller openings and thereby allows the pressure of finer structures. The method according to the invention involves only a single additional coating step for this purpose. The known method for producing a SiebdrĆ¼ckvorrichtung is thereby not significantly expensive or complicated.

Eine besonders einfache und kostengĆ¼nstige Beschichtungsmƶglichkeit wird durch eine Beschichtung gegeben, die nanokristallin, mit einem Kristalldurchmesser von weniger als 10 Nanometern ausgebildet ist.A particularly simple and cost-effective coating option is given by a coating which is nanocrystalline, with a crystal diameter of less than 10 nanometers.

In einem weiteren bevorzugten AusfĆ¼hrungsbeispiel wird bei dem erfindungsgemƤƟen Herstellungsverfahren eine Beschichtung mit einer Schichtdicke zwischen etwa 100 nm und etwa einigen Mikrometern erzeugt. Wie oben bereits dargestellt, erlauben diese Schichtdicken das Drucken von Feinstline-Strukturen mit einer hohen BestƤndigkeit.In a further preferred embodiment, a coating having a layer thickness of between about 100 nm and about a few micrometers is produced in the production method according to the invention. As already indicated above, these layer thicknesses allow the printing of fine-line structures with a high resistance.

Ebenso ist eine kostengĆ¼nstige Beschichtung durch ein Beschichtungsmaterial erreichbar, das eine Kohlenstoff-Verbindung mit einer diamantƤhnlichen Struktur (DLC = diamond like carbon) und/oder ein Fluorid und/oder eine fluorbasierte Verbindung, vorzugsweise PTFE, und/oder eine siliziumbasierte Verbindung enthƤlt. Eine weitere Verbesserung der Eigenschaften der Beschichtung kann erreicht werden, indem das Gewebe und/oder die Schablone auf ihrer Oberseite mit einer oleophilen (lipophil/-phoben, hydrophil/-phoben) Beschichtung und/oder auf der Unterseite des Gewebes und/oder der Schablone und/oder die ZwischenrƤume des Gewebes und/oder der Schablone mit einer oleophoben Beschichtung versehen werden.Likewise, an inexpensive coating can be achieved by a coating material which has a carbon compound with a diamond-like structure (DLC = diamond-like structure) carbon) and / or a fluoride and / or a fluorine-based compound, preferably PTFE, and / or contains a silicon-based compound. Further improvement of the coating properties can be achieved by placing the fabric and / or the stencil on top with an oleophilic (lipophilic / hydrophobic / hydrophobic) coating and / or on the underside of the fabric and / or the stencil and / or the interstices of the fabric and / or the template are provided with an oleophobic coating.

Beispielexample

Das Stahlgewebe einer Siebdruckvorrichtung wird nach einem Plasma-Reinigungsschritt mittels eines Plasma-CVD Verfahrens entweder mit einer silikonartigen amorphen OberflƤche mit ca. 100 nm SchichtstƤrke beschichtet oder mit einer DLC (Diamond Like Carbon) -Schicht von 1 Āµm (z. B. Handelsname CARBOCERĀ® der Firma PLASMA ELECTRONIC GmbH) versehen. Die DLC-Beschichtung ist deutlich hƤrter als die silikonartige, wobei die letztere dagegen bei niedrigeren Prozesstemperaturen aufgebracht werden kann. Die Beschichtung des Gewebes erfolgt bei einer Temperatur von ca. 80Ā°C oder entsprechend niedriger. AnschlieƟend wird die Schablone auf das Gewebe aufgebracht. Alternativ kann zusƤtzlich auch die Schablone mit dieser Beschichtung versehen werden. Die Abfolge hƤngt vom Material der Schablone und seiner WƤrmebestƤndigkeit ab.The steel mesh of a screen printing device is coated after a plasma cleaning step by means of a plasma CVD process either with a silicone-like amorphous surface with about 100 nm layer thickness or with a DLC (Diamond Like Carbon) layer of 1 .mu.m (for example, trade name CARBOCER Ā® from PLASMA ELECTRONIC GmbH). The DLC coating is significantly harder than the silicone-type, whereas the latter can be applied at lower process temperatures. The coating of the fabric takes place at a temperature of about 80 Ā° C or correspondingly lower. Then the template is applied to the fabric. Alternatively, in addition, the stencil can be provided with this coating. The sequence depends on the material of the stencil and its heat resistance.

Deutlich niedrigere Abscheidetemperaturen kƶnnen mit einer amorphen (glasartigen) Beschichtung erreicht werden. Diese silikonartige OberflƤche hat zwar den Vorteil der geringeren Prozesstemperatur, weist allerdings lediglich eine OberflƤchenhƤrte geringer als Glas auf. Es sind bei dieser Abscheidung 40Ā°C angestrebt im Vergleich zu 80Ā°C bei DLC Schichten, die wiederum HƤrten annƤhernd Diamant (Mohs 9-10) aufweisen. Alle Schichten werden im Plasma-CVD-Verfahren abgeschieden. Auch die oleophilen Schichten werden mit einem Plasma-CVD-Prozess aufgebracht und sind den DLC-Schichten Ƥhnlich. Lediglich ein anderer Zusatz von Dotiergasen verƤndert die OberflƤcheneigenschaften. Sich ausbildende WasserstoffbrĆ¼cken, OH-Gruppen oder Carboxyle verƤndern die OberflƤcheneigenschaften in Richtung oleo- (lippo- / hydro-) phil oder -phob. Ein Einbau von erhƶhten Sauerstoffanteilen fƶrdert den oleophilen Charakter der OberflƤche. Der Einbau von Silizium fƶrdert den oleophoben Charakter. Der Handelsname des oleophilen (hydrophile) Beschichtungsverfahrens der Firma PLASMA ELECTRONIC ist AQUA-CERĀ®. Significantly lower deposition temperatures can be achieved with an amorphous (glassy) coating. Although this silicone-like surface has the advantage of lower process temperature, but has only a surface hardness lower than glass. The aim of this deposition is 40 Ā° C compared to 80 Ā° C for DLC layers, which in turn have hardnesses close to diamond (Mohs 9-10). All layers are deposited by plasma CVD. The oleophilic layers are also applied by a plasma CVD process and are similar to the DLC layers. Only another addition of doping gases changes the surface properties. Forming hydrogen bonds, OH groups or carboxyls alter the surface properties in the direction of oleo (lipo / hydro) phil or phob. Incorporation of increased levels of oxygen promotes the oleophilic character of the surface. The incorporation of silicon promotes the oleophobic character. The commercial name of the PLASMA ELECTRONIC oleophilic (hydrophilic) coating process is AQUA-CERĀ®.
