Abstract
The utility model discloses a silk-screen printing board structure of a touch screen. The silk-screen printing board structure of the touch screen comprises a hollow frame body and a screen arranged at the hollow portion of the frame body, wherein a first light-sensitive adhesive layer and a second light-sensitive adhesive layer are sequentially coated on the surface of the screen, the first light-sensitive adhesive layer is exposed to form a hollow-out portion, and the second light-sensitive adhesive layer is exposed in a limited range of the first light-sensitive adhesive layer to form a pattern. The silk-screen printing board structure is a double-light-sensitive adhesive coating structure. One the premise that the silk-screen effect of a printing region is not influenced, the thickness of the light-sensitive adhesive of a non-silk-screen region of the silk-screen printing board is increased, a combining face of the light-sensitive adhesive and the screen is increased, the light-sensitive adhesive does not easily drop in the silk-screen process, and the silk-screen printing board does not easily deform, and the production quality is effectively guaranteed.
Description
Technical field
The utility model relates to the electronic product field, the silk-screen half tone structurally associated of special and touch-screen.
Background technology
Having wide range of applications of touch-screen, the ATM from the production equipment of industrial use to commercial use, electronic product fields such as the mobile phone from the electronic equipment of public information inquiry to consumer, digital camera.Multiple processing procedure is arranged in the production process of touch-screen, the silk-screen processing procedure is wherein a kind of, the compound half tone that the silk-screen half tone that uses in the touch-screen silk-screen operation adopts the polyester half tone usually or is made up of polyester webs and stainless steel grenadine, be the fixed angle of grenadine with 21-23 ° to be bonded on aluminium frame or the wooden frame with the tension force of 20N-28N by the net machine that stretches tight earlier during half tone is made, be coated with photoresists according to required figure again, can obtain the required half tone of silk-screen behind the exposure imaging.Find in the silk-screen process at present, half tone is prone to phenomenons such as distortion, stretching or photoresists come off, these all can be direct or indirect influence product quality, particularly photoresists come off and easily cause problems such as printed wire broken string, line or non-printing zone point be bad, and the utility model namely is the improvement of carrying out at above-mentioned defective.
The utility model content
The utility model provides a kind of touch-screen silk-screen half tone structure, can solve that half tone is prone to problems such as distortion, stretching or photoresists come off in the prior art.
For reaching above-mentioned purpose, technical solution of the present utility model is:
A kind of touch-screen silk-screen half tone structure, the gauze that includes the framework of hollow and be located at this framework hollow bulb, wherein order is coated with first photosensitive layer and second photosensitive layer on the face of this gauze, exposure forms hollow-out parts on this first photosensitive layer, and the exposure in the scope of first photosensitive layer hollow-out parts limitation of this second photosensitive layer forms pattern.
The thickness of this first photosensitive layer is between 8-12um.
The thickness of this second photosensitive layer is between 7-30um.
Adopt such scheme, compared with prior art, silk-screen half tone photoresists of the present utility model adopt two coating structures, utilize newly-increased photoresists to increase the thickness of non-printing zone, the non-printing zone of grenadine is directly filled up by photoresists, enlarge the faying face of photoresists and grenadine, make photoresists be not easy to come off, and then effectively improve the half tone quality, prolong half tone service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and concrete enforcement the utility model is elaborated.
As Fig. 1, shown in 2, a kind of touch-screen silk-screen of the utility model half tone structure, the gauze 2 that includes the framework 1 of hollow and be located at this framework hollow bulb, framework 1 adopts a kind of right angle aluminium frame, this gauze 2 can adopt polyester webs of the prior art or is fixed on the hollow bulb of framework 1 by the composite web that polyester webs and stainless steel grenadine are formed, coating one deck first photosensitive layer 3 on the face of gauze 2, coated face is blade face, the THICKNESS CONTROL of this first photosensitive layer 3 is between 8-12um, expose at first photosensitive layer 3 and form hollow-out parts 4 as the printing zone of half tone in the baking back, afterwards at this first photosensitive layer 3 and hollow-out parts 4 coatings second photosensitive layer 5, the THICKNESS CONTROL of this second photosensitive layer 5 is between 7-30um, this second photosensitive layer 5 exposes and form pattern 6 in the scope of the first photosensitive layer hollow-out parts, 4 limitations afterwards, this pattern 6 is in the scope of hollow-out parts 4, a kind of embodiment as shown in Figure 2, these hollow-out parts 4 exposures are frame structure, pattern 6 is in this square frame, the inside casing of this hollow-out parts 4 is than between the pattern 6 interior contraction 0.5-2mm, and housing extends out between about 10-30mm than pattern 6.
Adopt said structure, because silk-screen half tone photoresists of the present utility model adopt two coating structures, under the prerequisite that does not influence printing zone silk-screen effect, increased the thickness of the non-printing zone photoresists of half tone, enlarge the faying face of photoresists and gauze, photoresists are more difficult in the silk-screen process comes off, and half tone is not yielding, effectively guarantees product quality.
Claims (3)
1. touch-screen silk-screen half tone structure, the gauze that includes the framework of hollow and be located at this framework hollow bulb, it is characterized in that: order is coated with first photosensitive layer and second photosensitive layer on the face of this gauze, exposure forms hollow-out parts on this first photosensitive layer, and the exposure in the scope of first photosensitive layer hollow-out parts limitation of this second photosensitive layer forms pattern.
2. a kind of touch-screen silk-screen half tone structure as claimed in claim 1, it is characterized in that: the thickness of this first photosensitive layer is between 8-12um.
3. a kind of touch-screen silk-screen half tone structure as claimed in claim 1, it is characterized in that: the thickness of this second photosensitive layer is between 7-30um.
