Description
Technical field
The present invention relates to a kind of screen printing template; It has first screen printing template layer that comprises first breach and the second screen printing template layer that comprises second breach, thereby printed medium can pass said first breach from the end face of the said first screen printing template layer and said second breach is carried towards the direction of the substrate that can be arranged in their belows.
Background technology
When serigraphy or in the method for biting, printed medium is applied to screen printing template, utilizes subsequently along screen printing template end face guiding and move the breach that this screen printing template sent into printed medium by the scraper plate that perhaps moves near this end face guiding.Motion through the scraper plate one or many can be arranged at the substrate under it towards conveying of bottom surface direction and arrival with printed medium.Printed medium can not arrive by the screen printing template region covered, thereby on substrate, forms printed patterns (Druckbild), and this printed patterns corresponds essentially to the breach of this screen printing template.
The employing of serigraphy and screen printing template is known already and has passed through practice test.If yet the size of the breach in screen printing template is less; Printed medium will cause scraper plate under the situation of bearing relatively large power, to push screen printing template, so that also can be transported to the bottom surface and can on the road that goes there, not stick in these small gaps.This big pressure is imperfect, and this is because this has shortened the service life of screen printing template, and the wearing and tearing of the precision machined end face of screen printing template are also very fast relatively.
If after the printed medium of biting, remove screen printing template, under the small gap situation, especially can occur printed medium so and stick on the screen printing template and do not stick to the situation on the substrate from substrate.Like this, just lack printed medium on the substrate.Otherwise if printed medium sticks to (as defined) on the substrate, so a part of printed medium still can be retained in these breach.Cause the bed thickness of the printing zone on substrate to be had nothing in common with each other thus.
In addition, bed thickness also can occur based on covering of screen printing template carrier (for example fabric) has nothing in common with each other.With compare at crosspoint place, have more printed medium to pass template in the position of fabric opening.Under the higher situation of printed medium viscosity (wherein; Medium can be along lateral flow), the thickness type of trace (Druckauftrag) wide
has significant difference in height.
Summary of the invention
Therefore task of the present invention is to provide a kind of screen printing template; Utilize said screen printing template under the less situation of breach, on substrate, to obtain reliable trace; Said screen printing template is higher than the durability of former template, and on substrate, relatively widely also can obtain uniform bed thickness during the application to printed medium.
This task is resolved through the theme of independent claims.Favourable improved procedure of the present invention is the theme of dependent claims.
The present invention relates to a kind of screen printing template, it has the first screen printing template layer that comprises first end face and first bottom surface, wherein; Said template has first breach; Said first breach connects to said bottom surface from said end face, and wherein, said first breach has the printed medium inlet on said first end face; Export and on said first bottom surface, have printed medium; Wherein, the area of said inlet is overlapping at local area with said outlet at most perpendicular to said area projection the time, wherein; Said screen printing template has the second screen printing template layer that comprises second end face and second bottom surface; Wherein, said second end face of the said second screen printing template layer is connected with said first bottom surface of the said first screen printing template layer, wherein; The said second screen printing template layer has second breach, thereby printed medium can pass said first breach from the said end face of the said first screen printing template layer and said second breach is delivered on the substrate that can be arranged in their belows.
In this make of screen printing template, said printed medium not only by quadrature ground in other words perpendicular to the said end face of said screen printing template send into breach, and can carry towards the direction of off-normal.This has simplified the conveying of printed medium towards orientation substrate, thereby just can breach be passed in the printed medium conveying through scraper plate with less power consumption.Thereby can obtain the higher durability of screen printing template.According to an embodiment of the invention, the wall of said first breach in said outlet scope about said first bottom surface of said screen printing template greater than 0 ° and less than 90 ° angular range in be orientated.Thereby forming " separating seamed edge (Abrei β kante) ", it makes it possible to cut off printed medium with definite mode, and has avoided printed medium to stick to fully in first breach.
Particularly advantageously be, the wall of said first breach between its entrance and exit about the said bottom surface of the said first screen printing template layer greater than 0 ° and less than 90 ° angular range in be orientated.Thereby first breach that exists relative bottom surface to tilt, thereby, scraper plate has preferred orientations when moving, and printed medium can especially easily be admitted to first breach under the situation of this preferred orientations.Also exist in this embodiment and separate seamed edge.
If the cross section of said first breach is irregular between its entrance and exit, for example dwindle, so further strengthened cutting off to printed medium.
According to another embodiment of the present invention, at least one in these breach is provided with coating.Said coating has been dwindled the area that passes through of printed medium; And make trace have littler size, wherein, said coating has a thickness; Said thickness be at least said breach the minimum cross-section width 5%, and said coating to the contact angle of water in 0 ° to 90 ° scope.
Contact angle is the angle that the lip-deep drop of solid material relatively should the surface forms.Therefore; Under the situation of the contact angle in 0 ° to 90 ° scope; The relative coating surface of printed medium liquid or paste forms preferably and interacts, thereby when when the substrate of undertaking the printing of is removed screen printing forme, most printed medium keeps sticking in the breach of coating by this way.This is owing to separate effect of seamed edge and further simplified, thereby can print uniform bed thickness, does not print to substrate together from the breach of end face and do not have too much material.
According to another embodiment of the present invention; Breach is provided with coating; Thereby coating has been dwindled passing through area and making trace have littler size of printed medium, and wherein, said coating has a thickness; Said thickness be at least said breach the minimum cross-section width 5%, and said coating to the contact angle of water from greater than 90 ° to 150 ° scope.Only form the very little interaction of the relative coating surface of printed medium at this.Printed medium can be sent into breach with littler resistance.This external printed medium is bitten and after substrate is removed screen printing template, can be removed with very little cost and be retained in the printed medium in the breach.When substrate is removed screen printing forme, the printed medium of sending into breach only sub-fraction is retained in this breach.As a result, trace has the thickness that can equate with the thickness of screen printing forme.
Said first screen printing template layer and the said second screen printing template layer can one constitute.Yet the said second screen printing template layer also can be made up of the screen printing template layer that is independent of the said first screen printing template layer.Said independently screen printing template layer can be processed perhaps by photosensitive layer and be made up of the emulsion based on polyvinyl alcohol, capillary film or solid residue (Festresist).Said independently screen printing template layer also can have metal level, and said metal level applies through electroplating to apply.

The specific embodiment
Fig. 1 illustrates the cross-sectional view according to the first screen printing template layer 50 of screen printing template of the present invention.Screen printing template layer 50 has first breach 1, and wherein, first breach 1 has printed medium inlet 3 on first end face 2, and on first bottom surface 4, has printed medium outlet 5.
Like this structure first screen printing template layer 50, that is, the area 7 of inlet 3 is being folded with the area 8 of outlet 5 local at most during perpendicular to these area 7 projections along projecting direction 6 mutually.This means, perhaps these two areas 7 or 8 not overlapping, perhaps these two areas 7 or 8 are only partly overlapping.Below wherein area 7 and 8 partly overlapping region descriptions are faying surface 9.This faying surface 9 is all the time less than area 7 or 8.According to an embodiment of the invention, the size of faying surface 9 is no more than 30% of area 7 or area 8.Preferably, these two areas 7 and 8 not overlapping, thus just there is not faying surface 9 yet.
To the first screen printing template layer 50 shown in Figure 3, being orientated according to about 70 ° angular range about the bottom surface 4 of screen printing template layer 50 at inlet 3 and the wall 13 that exports between 5 of first breach 1 is referring to Reference numeral 14 at Fig. 1.Thereby first end face 2 of first breach 1 along its whole length from screen printing template 100 tilts to extend to first bottom surface 4.Under the situation of the first screen printing template layer 50, first breach 1 of printed medium 30 being sent into this inclination is easier than the breach of sending into perpendicular to the end face orientation of the first screen printing template layer.Fig. 2 illustrates printed medium 30, and it sends into first breach by means of scraper plate 10.For this reason, this scraper plate is pressed close to first end face, 2 slips of screen printing template layer 50 along the direction of motion 11.
Under situation shown in Figure 2, the printed medium 30 of sending into first breach 1 has fully arrived the substrate 20 that is positioned at the first screen printing template layer, 50 below and has contacted its surface.If in step subsequently, remove this screen printing template layer from substrate 20, the seamed edge 12 on the bottom surface 4 plays the effect that separates seamed edge so, thereby begins to cut off this printed medium from this seamed edge, referring to Fig. 3.The part of printed medium 30 is stayed on the substrate 20, illustrates as gable 32 here, and other parts of printed medium 30 are retained in the first screen printing template layer 50 simultaneously.Yet printed medium 30 is being that to separate seamed edge according to this predetermined with share in screen printing template layer 50 on the substrate, and can reproduce well, thereby realizes printed medium is uniformly applied on the substrate 20.
Fig. 4 illustrates the screen printing template 100 according to first embodiment.Screen printing template 100 has the first screen printing template layer 50 and the second screen printing template layer 51, and these two screen printing template layers firmly connect each other.Screen printing template 100 has two breach 1 in the first screen printing template layer 50, wherein, this first breach 1 ends in first bottom surface 4.Below this first bottom surface 4, construct the second screen printing template layer 51 with the mode that has ladder, thereby screen printing template 100 have second end face 53 and second bottom surface 54 with second breach 52.Second breach 52 has the wall that is orientated with the mode perpendicular to second end face 53 and second bottom surface 54.Second end face 53 is connected with first bottom surface 4 of the first screen printing template layer 50.Can gather from first end face 2 in this zone between first bottom surface 4 and second bottom surface 54 and be extruded the printed medium 30 that passes these breach 1 and second breach 52, and on substrate 20, form the trace 31 of broad.
The first screen printing template layer 50 can constitute with the second screen printing template layer, 51 one, referring to Fig. 5.Like this, the second screen printing template layer 51 can be made like this,, processes ladder by unique a kind of mould material that is.Yet also can independently the screen printing template layer 51 and the first screen printing template layer 50 be combined, to form screen printing template 100, as shown in Figure 4.This independently screen printing template layer 51 for example can be based on the photothermographic emulsion layer of polyvinyl alcohol, capillary film or solid residue, and (lithografisches Verfahren) forms ladder in this photothermographic emulsion layer by means of the photoengraving print process.Independently screen printing template layer 51 also can be realized through the mode of structuring electroplated coating, and concrete implementation is, the interim half tone that exists of structure on first bottom surface 4, with this independently the screen printing template layer be electroplated in this half tone.After applying, remove once more and should electroplate half tone (Galvanikform).
If remove screen printing template 100,, on trace 31, form protuberance 33 so in the outlet 5 in the past residing positions of first breach 1 referring to Fig. 4 from substrate 20.Yet since printed medium 30 in first breach 1 by being cut off, these swell 33 relatively low, thereby can obtain the relative homogeneous thickness that trace 31 extends along its width.
The gable 32 of printed medium 30 shown in broken lines in Fig. 4 is immediately following after substrate 20 is removed screen printing template 100, at first being left these gables 32.If yet printed medium has enough viscosity; Even this viscosity still allows to flow under the situation of the power effect that does not have other; So at the gable 32 of printed medium 30 on the upper surface of trace 31 along under the lateral flow; Thereby the almost balanced thickness type that obtains trace 31 is wide, and stays relatively low protuberance 33.
Certainly, trace has almost that this effect of thickness also appears in a kind of like this screen printing template in the same manner, and said screen printing template only has unique one first breach 1 on the contrary with embodiment according to Fig. 4.
