Abstract
The utility model discloses a kind of contraposition wiring board, comprise wiring board, in wiring board, be provided with circuit, the microscler both sides of wiring board are respectively provided with four location holes, eight location holes are followed closely corresponding with the sheet of the upper and lower film.Wiring board aligning accuracy of the present utility model is high, and contraposition is simple, quick, solves manual alignment precision low, overcomes the deficiency of skilled worker's contraposition crew shortage.
Description
Technical field
The utility model relates to the technical field of wiring board, specifically a kind of high accuracy contraposition wiring board.
Background technology
Make in contraposition operation at pcb board, existing is manual alignment, and this alignment method efficiency is low, the inadequate precision of contraposition, and for skilled worker's contraposition crew shortage.
Utility model content
It is high that the purpose of this utility model is to provide a kind of aligning accuracy, contraposition simply, contraposition wiring board fast.
For realizing above-mentioned object, the technical solution of the utility model is: a kind of contraposition wiring board, comprises wiring board, in wiring board, be provided with circuit, and the microscler both sides of wiring board are respectively provided with four location holes, and eight location holes are followed closely corresponding with the sheet of the upper and lower film.
Preferably, the diameter of described location hole is 3.2mm, and the diameter of sheet nail is 3.15mm.
The utility model by being respectively provided with four location holes on the microscler both sides of wiring board, follow closely corresponding when contraposition with the sheet of the upper film and the lower film, the upper film and the lower film are all provided with four sheet nails and four sheet nail, the sheet nail of the upper film follows closely arranged in dislocation with the sheet of the lower film, the sheet nail of the upper film is corresponding with the sheet nail of the lower film, the sheet nail of the lower film is corresponding with the sheet nail of the upper film, four sheet nails of the film in wiring board eight location hole correspondences and four sheet nails of the lower film are made during contraposition, such contraposition is simple, quick, improves aligning accuracy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is upper film structural representation;
Fig. 3 is lower film structural representation.
In figure: 1 wiring board, 2 location holes, the film on 3,4 times films, 5 nails, 6 nail.
Embodiment
As shown in Figure 1,2 and 3, contraposition wiring board of the present utility model, comprises wiring board 1, in wiring board 1, be provided with circuit, the microscler both sides of wiring board 1 is respectively provided with four location holes, 2, eight location holes 2 and the sheet of the upper and lower film 3,4 and follows closely 5 corresponding.In the present embodiment, the diameter of described location hole 2 is 3.2mm, and the diameter of sheet nail 5 is 3.15mm.
The utility model concrete operations are, in cooperation, the film 3 and the lower film 4 use, the upper film 3 and the lower film 4 are all provided with four sheet nails 5 and four sheet nail 6, the sheet nail of the upper film 3 follows closely arranged in dislocation with the sheet of the lower film 4, the sheet nail of the upper film 3 is corresponding with the sheet nail of the lower film, and the sheet nail of the lower film 4 and the sheet nail of the upper film 3 are for that.During contraposition operation, the upper film 3 is fixed on exposure table top upper ledge, the lower film 4 is fixed on exposure table top lower frame, wiring board 1 is placed on the lower film 4, make the location hole 2 of wiring board 1 at the sheet nail place of the lower film 4, the same time slice nail that simultaneously on upper ledge, the film 3 presses down to be bled exposure to positive nail, like this can by exposure person's one man operation, contraposition is simple, improves efficiency and aligning accuracy.
The feature that wiring board aligning structure of the present utility model is simple, reasonable, less manpower equally accurate is high is also the innovation to high precision multilayer and double sided board plate PCB contraposition.
The above is preferred implementation of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection range of technical solutions of the utility model.
