Abstract
The utility model relates to a film for manufacturing an inner figure of a printed wiring board, which comprises a front film and a back film, wherein the front film is provided with a first transparent para-structure, and the back film is provided with a second transparent para-structure corresponding to the first transparent para-structure. The utility model skillfully utilizes the nontransparent characteristic of the film, the first transparent para-structure is arranged on the front film, and the second transparent para-structure corresponding to the first transparent para-structure is arranged on the back film, so when inspecting the para position condition of the film, an inspector judges whether the first transparent para-structure and the second transparent para-structure are superposed through judging the light transmittance of the front film and the back film on the para-structures thereof, thereby judges the para position condition of the front film and the back film.
Description
[technical field]
The utility model belongs to the printed wire field, relates in particular to a kind of film that is used to make printed wire inner cord figure in the printed wire field.
[background technology]
Printed-wiring board (PWB) (Printde Circuit Board is called for short PCB) is the important electron parts, is the supporter of electronic devices and components, is the supplier that electronic devices and components are electrically connected.At present, when making printed wire inner cord figure, need check the interlayer alignment of the film, but because core material is without any figure, no any reference point before etching, whether within the acceptable range only rely on the visual contraposition that can't judge the core material two sides, at present in order to overcome this defective, make first plate earlier, and then first plate checked, check the interlayer alignment situation of first plate Job's tears plate two-side graph after etching, just produce in batches after qualified, but the defective of doing like this is, if first plate is defective, then first plate is directly scrapped, and needs to make first plate, and will after checking out the qualified situation of contraposition between first flaggy, just can manufacture, cause production efficiency lower.
[utility model content]
In order better to overcome the above-mentioned defective that the film is difficult to contraposition when making printed wire inner cord figure, the utility model provides a kind of film that is used to make printed wire inner cord figure.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of film that is used to make printed wire inner cord figure is provided, comprise the front film and the reverse side film, the described front film is provided with the first printing opacity aligning structure, and the described reverse side film is provided with and the corresponding second printing opacity aligning structure of the described first printing opacity aligning structure.
Further improvement of the utility model: the described first printing opacity aligning structure is arranged on around the film of described front, the described second printing opacity aligning structure be arranged on the described reverse side film around.
Further improvement of the utility model is: the described first printing opacity aligning structure has two at least, and the described second printing opacity aligning structure has two at least.
Further improvement of the utility model is: the printing opacity width of the described first printing opacity aligning structure is 0.05 millimeter, and the printing opacity width of the described second printing opacity aligning structure is 0.05 millimeter.
Further improvement of the utility model is: the described first printing opacity aligning structure is a cruciform, and the described second printing opacity aligning structure is a cruciform.
Compared with prior art, the beneficial effect that the utlity model has is: pass through such scheme, utilize the lighttight characteristic of the film cleverly, by the first printing opacity aligning structure is set on the film of described front, on the described reverse side film, be provided with and the corresponding second printing opacity aligning structure of the described first printing opacity aligning structure, make the supervisory personnel when checking the alignment situation of the film, to passing through to judge the penetrability of the pros and cons film on its aligning structure, judge whether the described first printing opacity aligning structure overlaps with the described second printing opacity aligning structure, and then judge the alignment situation of the described front film and the described reverse side film.
[description of drawings]
