Abstract
The utility model discloses a composite screen printing plate, which comprises a screen frame, a silk screen and a screen printing plate, wherein the screen printing plate is fixed to the screen frame by the silk screen; the silk screen comprises two layers of polyester screens which are arranged from top to bottom; the screen printing plate is a metal sheet on which patterns are printed; the patterns are burnt and cast by laser; and the edge of the metal sheet is clamped between the two layers of polyester screens and is bonded with the polyester screens by glue. Due to the adoption of a composite structure, the screen printing plate has high capacity of resisting fatigue deformation and plastic deformation by the two layers of polyester screens which are arranged from top to bottom and can be restored to the original position well, and the screen printing patterns are burnt and cast by laser; according to the high-accuracy screen printing plate, the precise screen printing of a high-density circuit board is facilitated, the scrapping of the circuit board caused by the screen printing can be prevented effectively, and the yield of the manufacturing of the circuit board is improved.
Description
Technical field
The utility model relates to a kind of printing equipment, particularly relates to a kind of compound printing screen plate.
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, directly be positioned over circuit board below the printing screen plate with wire mark pattern, let 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 himself unique advantage: small investment, and expense is low, and technology is prone to grasp, and is convenient to promote development.The half tone of this kind printing comprises screen frame and screen cloth; Screen cloth is generally polyester webs and stainless steel cloth material, and polyester webs elasticity meets the demands, but insufficient strength is high; When screen cloth is fixed on screen frame; Tension force can not be too big, and along with the requirement of screen painting to precision and quality, the conventional polyester screen cloth can not satisfy these high requests.
Along with circuit board develops to microminiaturized, densification direction gradually; In the circuit board making process, need carry out high-precision screen painting; But the printing screen plate of existing printing screen plate preparation method made can't satisfy the needs that high density circuit board is made because wire mark pattern precision is lower; Even the circuit board that can cause scraps, thereby influences the yield of circuit board making.
Summary of the invention
To the deficiency of prior art, the purpose of the utility model is, a kind of compound printing screen plate is provided, and when adapting to the demand of high accuracy screen painting of high density circuit board, guarantees that screen cloth has better elastic and tensile force.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of compound printing screen plate comprises screen frame, silk screen and half tone; Half tone is fixed on the screen frame through silk screen; Said silk screen comprises the two layers polyester net of arranging up and down, and said half tone is the sheet metal that is printed on pattern, and pattern adopts laser to burn casting and forms; Said sheet metal edge clamping is between the two layers polyester net, and through the glue adhesion.
Aforesaid a kind of compound printing screen plate, it is characterized in that: being shaped as of said screen frame is square.
Aforesaid a kind of compound printing screen plate is characterized in that: said screen frame is aluminium frame or cast iron frame.
Aforesaid a kind of compound printing screen plate is characterized in that: said sheet metal is an aluminium flake.
The beneficial effect of the utility model is: adopt composite construction; Make printing screen plate possess the stronger antifatigue distortion and the ability of plastic deformation through two layers polyester net up and down, can be good at returning to the home position, simultaneously; Adopt laser ablation to form the wire mark pattern; This high accuracy printing screen plate helps high density circuit board and carries out accurate screen painting, can effectively prevent owing to the circuit board that screen painting causes is scrapped, and improves the yield of circuit board making.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the embodiment of the utility model: as shown in Figure 1, a kind of compound printing screen plate comprises screen frame 1, silk screen 2 and half tone 3; Being shaped as of screen frame 1 is square, is aluminium frame or cast iron frame.Half tone 3 is fixed on the screen frame 1 through silk screen 2, and silk screen 2 comprises the two layers polyester net of arranging up and down, and half tone 3 is for being printed on the sheet metal of pattern 4, and sheet metal is an aluminium flake.Pattern 4 adopts laser to burn casting and forms, and the sheet metal edge clamping is between the two layers polyester net, and through the glue adhesion.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed embodiment.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection domain of the utility model.
Claims (4)
1. compound printing screen plate; Comprise screen frame, silk screen and half tone, half tone is fixed on the screen frame through silk screen, it is characterized in that: said silk screen comprises the two layers polyester net of arranging up and down; Said half tone is the sheet metal that is printed on pattern; Pattern adopts laser to burn casting and forms, and said sheet metal edge clamping is between the two layers polyester net, and through the glue adhesion.
