Abstract

The utility model discloses a common screen stencil for screen printing. The common screen stencil comprises a screen frame, and a screen fixed on the screen frame, wherein a protective film pattern to be printed is arranged on the screen; and the protective film pattern comprises plurality rows of parallel strip-shaped rectangles, with each row including only one strip-shaped rectangle. The common screen stencil is suitable for trail production of different samples, and can effectively lower the manufacture cost.

Description

The public half tone of a kind of serigraphy

Technical field

The utility model belongs to the flexible print wiring board manufacturing process technology field, is specifically related to the public half tone of a kind of serigraphy.

Background technology

When making flexible printed circuit board, generally serigraphy be need use, printing diaphragm or literal on pcb board are used for.Can make circuit very clear, full by serigraphy.

Fig. 1 and Fig. 2 disclose a kind of application mode of traditional silk-screened, and wherein, Fig. 1 is a kind of structural representation of traditional silk-screened half tone; Fig. 2 is a kind of application schematic diagram of screen printing screens shown in Figure 1.

See Fig. 1 and Fig. 2, traditional serigraphy all is the different requirements according to single sample, designs different half tones, on a silk screen, prints same sample.See Fig. 1, traditional screen printing screens comprises screen frame frame (1) and is fixed on silk screen (2) on the screen frame frame (1); Described silk screen (2) is provided with waits to print diaphragm pattern (3), described wait to print diaphragm pattern (3) comprise the end that is positioned at top and low side capable (3-1) and be positioned between two end row (3-1) in the middle of row (3-2); Described end capable (3-1) is the single file pattern that is formed by a plurality of little rectangles (3-3) repeated arrangement; Row (3-2) is the duplicate rows pattern that is formed by a plurality of little rectangles (3-3) repeated arrangement in the middle of described.See Fig. 2, need to prove that each the sample figure (6) among Fig. 2 is not on silk screen, but on pcb board to be printed; This traditional silk-screened half tone can effectively be enhanced productivity and reduce cost when producing in enormous quantities.But also there is following shortcoming in this traditional silk-screened half tone: this half tone complex manufacturing technology, cost is higher, at pilot sample and provide it to the purchaser when on probation, a kind of sample just needs a special-purpose silk screen half tone, and the known fact is, considerable sample need improve, or is not purchased, cause original silk screen to scrap, thereby cause significant wastage.

The utility model content

The purpose of this utility model provides and a kind ofly is applicable to multiple different trial-manufacture of sample, effectively reduces the public half tone of serigraphy of sample manufacturing cost.

The technical scheme that realizes the utility model purpose is: the public half tone of a kind of serigraphy comprises screen frame frame and the silk screen that is fixed on the screen frame frame; Described silk screen is provided with waits to print the diaphragm pattern; It is characterized in that: described to wait to print the diaphragm pattern be that strip rectangle and the every row that multirow be arranged in parallel has only a strip rectangle.

In the such scheme, described strip rectangle is preferably equidistant arrangement.

In the such scheme, the left and right sides of described strip rectangle is provided with locating hole.

In the such scheme, the frame setting at two ends, the contiguous described screen frame frame left and right sides, the two ends, the left and right sides of described strip rectangle.

In the such scheme, the distance of the frame at distance two ends, the described screen frame frame left and right sides, the two ends, the left and right sides of described strip rectangle is 5 millimeters to 20 millimeters.

The utlity model has positive effect:

(1) the utility model only is provided with a strip rectangle in the same delegation of silk screen; replace the traditional silk-screened half tone in delegation in order to save stamp-pad ink; the way of a plurality of pinpoint little rectangles is set; the utility model has the advantages that every row can effectively print the diaphragm at the same position place of same sample; multirow strip rectangle can print the diaphragm of a plurality of samples simultaneously; thereby when the small lot trial-manufacture of sample; can replace a plurality of traditional screen frames to use with a public screen frame, thereby reduce the trial-manufacture of sample cost significantly.In addition, the utility model accommodation is extensive, as long as sample less than line-spacing of the present utility model, all can use the utility model to come pilot sample basically.

Reference numeral is: screen frame frame 1, and frame 11, silk screen 2 waits to print diaphragm pattern 3, end row 3-1, middle row 3-2, little rectangle 3-3, strip rectangle 4, locating hole 5, sample figure 6.

The specific embodiment

(embodiment 1)

Fig. 3 and Fig. 4 have shown a kind of specific embodiment of the present utility model, and wherein Fig. 3 is a kind of structural representation of the present utility model; Fig. 4 is the application schematic diagram of the public half tone of serigraphy shown in Figure 3.

Present embodiment is a kind of public half tone of serigraphy that is used for pilot sample, sees Fig. 3, comprises screen frame frame 1 and the silk screen 2 that is fixed on the screen frame frame 1; Described silk screen 2 is provided with waits to print diaphragm pattern 3; It is described that to wait to print diaphragm pattern 3 be that strip rectangle 4 and the every row that multirow be arranged in parallel has only a strip rectangle 4.The left and right sides of described strip rectangle 4 is provided with locating hole 5.Described strip rectangle 4 runs through the two ends, the left and right sides of silk screen 2 basically, the frame 11 that also is the two ends, contiguous described screen frame frame 1 left and right sides, two ends, the left and right sides of strip rectangle 3 is provided with, in the present embodiment, the distance of the frame 11 at the distance two ends, described screen frame frame 1 left and right sides, two ends, the left and right sides of described strip rectangle 4 is 10 millimeters, in the concrete practice, this distance can be selected in 5 to 20 millimeters.

In the present embodiment, described strip rectangle 4 is equidistantly arranged.

See Fig. 2, need to prove that each the sample figure 6 among Fig. 2 is not on silk screen, but on pcb board to be printed.Present embodiment can utilize a public half tone to print diaphragm simultaneously for the several samples pattern, uses so present embodiment is particularly suitable for the small lot trial-manufacture of sample.

Present embodiment only is provided with a strip rectangle in the same delegation of silk screen; replace the traditional silk-screened half tone in delegation in order to save stamp-pad ink; the way of a plurality of pinpoint little rectangles is set; the advantage of present embodiment is the diaphragm that every row can effectively print the same position place of same sample; multirow strip rectangle can print the diaphragm of a plurality of samples simultaneously; thereby when the small lot trial-manufacture of sample; can replace a plurality of traditional screen frames to use with a public screen frame, thereby reduce the trial-manufacture of sample cost significantly.In addition, present embodiment accommodation is extensive, as long as sample all can use present embodiment to come pilot sample less than the line-spacing of present embodiment basically.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
