Description
Technical field
The present invention relates to a kind of screen printing forme, it has screen printing stencil carrier and screen printing stencil, and said screen printing stencil is arranged on the bottom surface of said screen printing stencil carrier.
Background technology
When serigraphy or in the method for biting, printed medium is applied to screen printing forme, utilizes subsequently along screen printing forme end face guiding and move the breach that this screen printing forme sent into printed medium by the scraper plate that perhaps moves near this end face guiding.Some screen printing formes have the screen printing stencil carrier with first breach, and these first breach are so constructed, that is, they connect to the bottom surface from the end face of this screen printing stencil carrier.Can on the bottom surface of screen printing stencil carrier, screen printing stencil be set then, this screen printing stencil has second breach, and wherein, second breach overlaps with first breach of screen printing stencil carrier local at least.Just can the printed medium conveying be arranged at the substrate under it through first breach and the arrival of second breach through the scraper plate one or many in the motion on the screen printing stencil carrier.Printed medium can not arrive the screen printing stencil region covered, thereby on substrate, forms printed patterns (Druckbild), and this printed patterns corresponds essentially to the breach of this screen printing stencil.
The employing of serigraphy and screen printing forme is known already and has passed through practice test.Yet,, the printed medium conveying is being had difficulties aspect narrow and small breach through screen printing forme along with breadth to be printed (zu druckenden Bahnen) more and more littler (when for example being used for solar cell).Printed medium can't arrive substrate sometimes, but keeps sticking in the breach, and the result causes and on substrate, do not realize printing fully.
On narrow breadth, print if desired, can utilize scraper plate printed medium to be applied on the screen printing stencil carrier that is provided with narrow and small breach so, said scraper plate guiding under the situation of bearing very big pressure towards the screen printing stencil carrier end face moves.Like this, the possibility that printed medium sees through elongated narrow and small breach is just higher, thereby arrives at the substrate of undertaking the printing of.But shortcoming is here, and the end face of screen printing stencil carrier weares and teares at short notice, and the service life of screen printing forme is also shorter.
Summary of the invention
Therefore task of the present invention is to realize a kind of screen printing forme, utilizes this screen printing forme can form long and narrow printing format (Druckbahn) reliably, and wherein, this screen printing forme has high service life.Task of the present invention also is to provide a kind of method of making this screen printing forme.
Theme through independent claims solves these tasks.Favourable improved procedure of the present invention is the theme of dependent claims.

-screen printing stencil; It is constructed to and the firm mask layer that is connected in the bottom surface of said screen printing stencil carrier; Wherein, said mask layer is provided with second breach, and said second breach is so overlapping at local said first breach with said screen printing stencil carrier at least; So that printed medium can be through said first breach of said screen printing stencil carrier; From the end face of said screen printing stencil carrier, said second breach that passes said mask layer is sent to said bottom surface and can be arranged on the substrate under them
Wherein, Said screen printing stencil carrier and/or said mask layer are so constructed; That is, convexity is stretched to the regional interior of at least one said first or second breach and is reduced the area that passes through that is used for printed medium of said first or second breach, wherein; The thickness of the convexity in said first gap regions is less than the thickness of said screen printing stencil carrier, and/or the thickness of the convexity of said second breach is less than the thickness of said screen printing stencil.
Convexity in breach makes that the cross section of this breach is not along its whole length, but only one among a small circle in by being dwindled.Outside this zone, this breach can constitute commodiously, has dwindled the cross section of breach certainly through this convexity, wherein, and can be so that printed medium be transferred through said breach.Though this makes the breach on convexity can have spacious cross section, but still allow to form meticulous printing format.Therefore need not very expensive, just can so that the relative screen printing stencil of screen printing stencil carrier accurately locate so that the first less breach of cross section overlaps with the second also very little breach of cross section in the part at least.Opposite is to process with common machining accuracy.In addition, the broad breach that is used for inserting into the inner to convexity applies the power of printed medium less than the power that applies printed medium to the overall very little breach of cross section.In addition, the convexity in screen printing stencil or screen printing stencil carrier has increased their bending rigidity and tensile strength.Therefore, when the screen printing stencil carrier end face moved, screen printing forme will be stretched than amplitude ground at scraper plate, thereby its geometry has kept more high reliability.Therefore this screen printing forme has higher service life.
Mask layer can have metal, and preferably has nickel.Mask layer also can be processed by light-sensitive material.For example be suitable for making this mask layer at polyvinyl alcohol, capillary film or the suprabasil emulsion of solid residue (Festresist).
Preferably, said convexity is extended along the breach wall, thereby can realize through evenly the dwindling of area, and can the extruding printed medium through the time, apply load to convexity equably.Like this, this convexity as aperture (Blende) play a role.
Preferably, said convexity has the surface that comprises a radius of curvature.This radius of curvature has reduced the frictional resistance when printed medium is inner through breach in this breach, thereby can realize being pressed through with less power consumption.
If screen printing stencil has thickness and protruding thickness with 1 micron to 25 microns less than 30 microns, so just realized above-mentioned advantage well.Preferably, make through this convexity and saidly reduced 5% at least through area.
Screen printing stencil carrier and screen printing stencil can be processed by metal material.Can be constructed to mask layer at this screen printing stencil, said mask layer has nickel.This material can apply through electroplating deposition simply.
The method that is used to make said screen printing forme has following steps:
-preparation substrate
-formation first half tone on said substrate
-be electroplated to said substrate with the first metal layer is structured
-formation second half tone on said the first metal layer
-with second metal-layer structureization be electroplated to said the first metal layer, wherein, said the first metal layer forms screen printing stencil carrier, and said second metal level forms screen printing stencil;
-throw off said the first metal layer from said substrate;
-remove said first half tone and said second half tone, thus in said the first metal layer, form first breach, and in said second metal level, form second breach;
-wherein, said the first metal layer is electroplated on said first half tone local at least, and/or said second metal level is electroplated on said second half tone, to form at least one convexity local at least.
Can in a step, need not other structuring measures through electroplating deposition and just realize dwindling of protruding growth and cross section.Needn't adopt etching.Electroplating deposition can also form a convexity, and it causes the almost arbitrarily small area that passes through of breach.Under extreme case, protruding even can the complete closed breach.
Protruding formation has been played positive role to the mechanical stability of screen printing forme, and this is because formed " T shape element ".With with the plating mode manufacturing, the A/F screen printing forme consistent with bed thickness compare, the tensile strength of the masterplate of the present invention of its this more than having aspect tensile strength " T shape element " is much little.
