Abstract
The invention relates to a network of SMT laser template and relative network frame adhesive structure. The adhesive structure is formed by a network frame, a network, a bottom adhesive layer, and a face adhesive layer, wherein the outer sides of the network are inside the outer sides of the network frame, the outer sides of the bottom adhesive layer are layered with the outer sides of the network, the outer ides of the face adhesive layer are between the outer sides of the network frame and the outer sides of the bottom adhesive layer. Each edge of the network is fixed on the network frame via bottom adhesive layer whose its end is covered by the face adhesive layer, to avoid exposing network end, and avoid the network end being touched by outer force or immerged by solvent washing agent. The invention has advantages in simple structure or the like.
Description
Technical field
The invention belongs to the manufacturing of SMT laser template, particularly relate to the grenadine and the screen frame cementing structure of SMT laser template.
Background technology
Laser template is a kind of printing stencil the most frequently used in the present SMT industry, it is by the steel template of laser cutting and support the aluminium section bar screen frame of steel template and polyester or stainless steel wire grenadine constitute, window in the grenadine is fixed in the template edge splicing, and the grenadine periphery is tightened and gluedd joint and is fixed in screen frame.The quality of laser template quality is not the laser cutting quality, also comprises the quality of above-mentioned steel die board supporting structure, as the firm degree of screen frame flatness, grenadine tension force and grenadine and screen frame splicing.
Practice shows whether the splicing of grenadine and screen frame also is one of subject matter that influences the laser template durability firmly, and coming unstuck in the part of grenadine is its main forms.
In the prior art, the cementing structure that grenadine and screen frame adopt, specifically grenadine neighboring and screen frame outer side edges are evened up, primer layer and face glue-line overlap fully, wherein the outer side edges of primer layer and face glue-line overlaps with the screen frame outer side edges, the inner side edge of primer layer and face glue-line is positioned at the inboard of screen frame inner side edge, usually with screen frame inner side edge 2-3mm apart.
There is the open defect that exposes grenadine end edge in above-mentioned cementing structure, and the grenadine end is along under external force or cause local phenomenon of coming unstuck under the infiltration of leaning solvent easily in the cleaning process before using laser template.
Summary of the invention
The present invention is in order to solve the technical problem that grenadine of the prior art and screen frame cementing structure exist to expose grenadine end edge, and discloses a kind of grenadine and the screen frame cementing structure that can effectively avoid the SMT laser template that the grenadine part comes unstuck.
The present invention takes following technical scheme by the above-mentioned technical problem that solves the existence of grenadine of the prior art and screen frame cementing structure: this cementing structure is made up of screen frame, grenadine, primer layer and face glue-line, each outer side edges of its grenadine is positioned at the inboard on screen frame respective outer limit, the primer layer outer side edges overlaps with grenadine respective outer limit, and face glue-line outer side edges is between screen frame respective outer limit and primer layer outer side edges.
The present invention can also take following technical measures:
The distance of the described primer layer outer side edges that coincides and grenadine outer side edges and respective frame outer side edges is 5-7mm.
The distance of described glue-line outer side edges and respective frame outer side edges is 3-5mm.
Described primer layer inner side edge is positioned at the outside on screen frame respective inside limit, and face glue-line inner side edge is between screen frame respective inside limit and primer layer inner side edge.
The distance of each inner side edge of described primer layer and respective frame inner side edge is 4-5mm.
Beneficial effect of the present invention and advantage are: each edge of the grenadine of this cementing structure is fixed in screen frame by the primer layer splicing, its end is along then being covered fully by the face glue-line, fundamentally solved the technical problem that exposes grenadine end edge, can effectively avoid laser template external force in cleaning process to touch the infiltration of grenadine end edge or leaning solvent, so the grenadine of this cementing structure is not prone to local degumming phenomenon.In addition, the unusual characteristics of the concrete operations technology of this cementing structure.The outstanding advantage of simple in structure, the anti-obvious results of coming unstuck that the present invention has.
Accompanying drawing 1 embodiment 1 part-structure partial cutaway schematic.
Description of drawings
Accompanying drawing 2 embodiment 2 part-structure partial cutaway schematic.
Number in the figure: 1 screen frame, 1-1 inner side edge, 2 grenadines, 3 primer layers, 4 glue-lines, 5 steel templates.
Further specify the present invention below in conjunction with embodiment and accompanying drawing thereof.
The specific embodiment
Because therefore the position symmetry of laser template only provides upper left corner structure partial generalized section.
The primer layer 3 of embodiment 1 overlaps with the inner side edge of face glue-line 4, can select in the 2-3mm scope apart from screen frame 1 inner side edge 1-1, and present embodiment is selected 2mm, and this architectural feature is same as prior art.
Embodiment 2 as shown in Figure 2, this cementing structure is made up of grenadine 2, primer layer 3 and the face glue-line 4 of screen frame 1, stainless steel wire material, grenadine 2 each outer side edges are positioned at the inboard on screen frame 1 respective outer limit, primer layer 3 outer side edges overlap with grenadine 2 respective outer limits, the primer layer that overlaps and the distance of grenadine outer side edges and respective frame outer side edges can be selected in the 5-7mm scope, and present embodiment is selected 5mm.Face glue-line 4 outer side edges can be selected in the 3-5mm scope with the distance of screen frame 1 outer side edges between screen frame 1 outer side edges and corresponding primer layer 3 outer side edges, present embodiment 2 selected 3mm.
The primer layer 3 of embodiment 2 does not overlap with the inner side edge of face glue-line 4, and primer layer 3 inner side edges can be selected in the 4-5mm scope apart from screen frame 1 inner side edge 1-1, present embodiment 2 selected 5mm.The inner side edge of face glue-line 4 is between screen frame 1 respective inside limit and primer layer 3 inner side edges, and the inner side edge of face glue-line 4 can be selected in the 3-5mm scope apart from screen frame 1 inner side edge 1-1, and present embodiment is selected 3mm.
Below with Fig. 2 embodiment 2 description operation technologies: stretching tight the qualified basic upper edge screen frame 1 inside and outside side of net and cover each 5mm of screen frame respectively and paste U.S. line adhesive tape, coating primer layer 3 between two adhesive tapes is as 5525 glue.Coating is finished and to be removed two adhesive tapes, treat primer layer 3 dryings after, along screen frame 1 inside and outside side and cover each 3mm of screen frame respectively and paste U.S. line adhesive tape, coated face glue-line 3 between two adhesive tapes is as epoxide-resin glue.Coating is complete to remove two adhesive tapes, treats to carry out the fixing of steel die plate 5 after face glue-line 3 dryings.Adopt the prior art processing steel template 5 of screen frame and grenadine cementing structure and fixedlying connected of grenadine 2 among the embodiment 2.
