Abstract
The utility model relates to a silk-screen printing screen plate. The silk-screen printing screen plate comprises a rectangular screen frame and screen cloth arranged inside the screen frame, the screen cloth is formed by knitting warps and wefts, the warps and the wefts are fixed on rims of the screen frame, and the screen cloth is obliquely arranged inside the screen frame to enable the warps and the wefts to be not perpendicular to the rims on which the warps and the wefts are fixed respectively. By obliquely arranging the screen cloth inside the screen frame, the silk-screen printing screen plate enables the warps and the wefts of the screen cloth to cross obliquely during printing, and compared with an existing perpendicularly-arranged screen body, the formed mesh arrangement mode shortens printing gaps among meshes, so that the flatness of circuit edges is improved, the wavy lines are reduced, and the accuracy and the qualified rate of products are greatly improved.
Description
Technical field
The utility model relates to the printed substrate field, is a kind of silk-screen half tone specifically.
Background technology
Screen painting is a kind of multiduty printing technology, and it is playing the part of important role in field of circuit boards always, and it is the key that realizes accurate coating such as circuit board printing ink, viscose glue and scolding tin.In the circuit board making process, during screen painting, circuit board directly is positioned over below the printing screen plate with wire mark pattern, allow printing ink, viscose glue and scolding tin etc. in the wire mark pattern application of passing half tone under the squeezing action of scraper presumptive area to the circuit board.
Screen painting has the advantage of himself uniqueness: small investment, and expense is low, and technology is easily grasped, and is convenient to promote development.The half tone of this kind printing comprises screen frame and screen cloth, and screen cloth is generally polyester screen cloth or stainless steel wire cloth, and during making, screen cloth generally is that forward is arranged in the screen frame, and namely the warp of screen cloth is the vertical setting of 90 degree with the frame of the screen frame that will fix respectively with parallel.This half tone often causes the edge of circuit not neat when printing, is easy to generate wavy lines, influences precision and the qualification rate of product.
The utility model content
In order to overcome the defective of above-mentioned prior art, technical problem to be solved in the utility model provides a kind of silk-screen half tone that can effectively improve the circuit flatness of edges.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of silk-screen half tone, comprise rectangle screen frame and the screen cloth that is located in the screen frame, described screen cloth is formed by warp and parallel braiding, and described warp and parallel are fixed on the frame of described screen frame, described screen cloth is oblique to be arranged in the described screen frame, makes that warp and parallel and the frame of fixing separately are not perpendicular.
Wherein, described warp and parallel and separately the angle between the fixing frame be 45 degree.
Wherein, described screen cloth comprises the stainless steel wire cloth that is positioned at the screen cloth center and is positioned at the polyester screen cloth of stainless steel wire cloth periphery, the inward flange of the edge of described stainless steel wire cloth and described polyester screen cloth interconnects, the outward flange of described polyester screen cloth is fixed on the described screen frame, and described stainless steel wire cloth is provided with pattern area.
Wherein, the edge bonding connection of the inward flange of described polyester screen cloth and described stainless steel wire cloth.
Wherein, evenly be coated with the light-cured resin binding agent on the described polyester screen cloth.
Wherein, the coating thickness of described light-cured resin binding agent is 10～15 μ m.
The utility model compared with prior art, has following beneficial effect: by being arranged in the screen frame screen cloth is oblique, warp and the parallel of screen cloth are diagonal cross when making printing, formed mesh arrangement mode has dwindled the printing gap between the mesh for the half tone of existing forward setting, thereby improved the flatness at circuit edge, reduced the generation of wavy lines, the precision of product and qualification rate are greatly improved.
Description of drawings
Figure 1 shows that the structural representation of the utility model embodiment.
Label declaration:
1, screen frame; 2, screen cloth; 3, mesh;
10, frame; 11, frame; 20, stainless steel wire cloth; 21, polyester screen cloth;
200, warp; 210, parallel.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also shown in Figure 1, the silk-screen half tone of present embodiment, comprise rectangle screen frame 1 and the screen cloth 2 that is located at 1 li of screen frame, described screen cloth 2 is formed by warp 200 and parallel 210 braidings, described warp 200 and parallel 210 are fixed on the frame 10,11 of described screen frame 1, described screen cloth 2 oblique being arranged in the described screen frame 1 make that warp 200 and parallel 210 are not perpendicular with fixing separately frame 10,11.
Adopt the silk-screen half tone of said structure, warp 200 and the parallel 210 of its screen cloth 2 when printing will be diagonal cross, formed mesh arrangement mode has dwindled the printing gap between the mesh 3 for the silk-screen half tone of existing forward setting, thereby improved the flatness at circuit edge, reduced the generation of wavy lines, the precision of product and qualification rate are greatly improved.
Further, described warp 200 and parallel 210 and separately the angle between the fixing frame 10,11 be 45 degree, thereby farthest dwindle the printing gap between the mesh 3, improve the flatness at circuit edge.
In the above-described embodiments, please continue with reference to shown in Figure 1, described screen cloth 2 comprises the stainless steel wire cloth 20 that is positioned at screen cloth 2 centers and the polyester screen cloth 21 that is positioned at stainless steel wire cloth 20 peripheries, the inward flange of the edge of described stainless steel wire cloth 20 and described polyester screen cloth 21 interconnects, the outward flange of described polyester screen cloth 21 is fixed on the described screen frame 1, and described stainless steel wire cloth 20 is provided with pattern area.The mode that the screen cloth of employing polyester screen cloth and two kinds of materials of stainless steel wire cloth is connected is mutually thrown the net, can effectively remedy the problem of the insufficient strength that the bad and simple employing of resilience polyester screen cloth that simple employing stainless steel wire cloth causes causes, the antifatigue distortion of screen cloth and the ability of plastic deformation have been improved, thereby prolong the service life of half tone, reduce the usable floor area of stainless steel wire cloth simultaneously, saved production cost greatly.
Wherein, the edge of the inward flange of described polyester screen cloth 21 and described stainless steel wire cloth 20 is by the glue bonding connection, evenly be coated with light-cured resin binding agent (UV glue on the described polyester screen cloth 21, be a kind of completely crued resinoid bond of ultraviolet ray ability that needs to absorb) carry out edge sealing, the coating thickness of described light-cured resin binding agent is 10～15 μ m.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
