Abstract
The utility model relates to an exposure film for resistance welding pattern, which is made from films with exposure areas, wherein positioning through-holes are made at the edge of the film, and the positioning through-holes are positioned at four corners of the film. The utility model has simple structure, only black films are used during the exposure, only one operator is needed for completion of the exposure treatment, and the positioning between the film and the circuit board is precise, so that the film is an exposure film for resistance welding pattern capable of saving material and human resources and facilitating operations.
Description
Technical field
The utility model belongs to the printing circuit board technical field, especially a kind of welding resistance graph exposure film.
Background technology
The making of the welding resistance figure in the circuit board processing technology is that film is placed on the circuit board, then on exposure machine to exposure.The structure of exposed plate 2 as shown in Figure 3, the position, intermediate portion is an exposure region 3, four jiaos of places at film make rectangular through hole 7 respectively, then upper and lower two film plasters are attached to the upper and lower surface of circuit board 6, elder generation observes the position of films and circuit board with five times of magnifieres and through after manually adjustment makes the two accurate contraposition, with adhesive plaster 8 upper and lower film and circuit board is fixed again.In exposure process, shading position on the film need be wanted consistent with the graph position of circuit board surface, have following shortcoming when using existing contraposition fixed form: 1. film will use red (can printing opacity be convenient to contraposition), and red to be the black-film reproduction make, increased cost; 2. exposure machine needs three people to operate simultaneously, and the operating personnel of exposure machine both sides are responsible for the contraposition of film and circuit board, and another operator is responsible for operating exposure machine, the serious human resources of having wasted; 3. the fastness during immobilization with adhesive tape is not fine, occurs the problem that dislocation is moved easily; 4. operating personnel need be through the training contraposition of film on top of.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, with low cost, save human resources, improve the welding resistance graph exposure film of exposure work efficiency.
The technical scheme that the utility model is taked is:
A kind of welding resistance graph exposure film is made up of the film that is shaped on exposure region, and it is characterized in that: the edge of film is shaped on positioning through hole.
And described positioning through hole is positioned at four jiaos of film.
Advantage of the present utility model and good effect are:
1. the edge of this film is shaped on positioning through hole, with also be shaped on through hole on the circuit board plate body of this positioning through hole contraposition, add man-hour in exposure, in the through hole of last film, circuit board and following film, install the register pin nail-plate and make the firm location of three, this fixed form is compared more firm with existing immobilization with adhesive tape mode, and be disposable location, same exposure process only needs an operator promptly can finish.
2. each angle all is provided with two positioning through hole in four of this film jiaos, and one of them is to install the register pin nail-plate, and another is that register pin nail-plate down is installed, and it is tightr that this structure makes between upper and lower film and the circuit board, and exposure effect is better.
3. keep bigger gap between two positioning through hole that one of them angle in four of this film jiaos is provided with, be not prone to the situation of putting back when film is used, improved operating personnel's work efficiency, guaranteed the quality of exposure.
4. the utility model is simple in structure, uses black-film during exposure, only needs operating personnel promptly can finish exposure processing, and film and circuit board contraposition are accurate, are a kind of saving material and human resources, the welding resistance graph exposure film of being convenient to operate.

Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of welding resistance graph exposure film, as shown in Figure 1 and Figure 2, form by the film 2 that is shaped on exposure region 3, edge at four angles of film is shaped on positioning through hole 1, two positioning through hole are all made at each angle, and one of them is to be used to install register pin nail-plate 4, and another is to be used to install down register pin nail-plate 5, this structure makes between upper and lower film and the circuit board tightr, and exposure effect is better.
Principle of work of the present utility model is:
1. on circuit board, process through hole with the positioning through hole contraposition of film;
Upper and lower film and circuit board is stacked 2.;
3. will go up the register pin nail-plate and insert in the positioning through hole, will descend the register pin nail-plate to insert another positioning through hole;
4. after installing all register pin nail-plates, place it on the exposure machine;
5. the unlatching machine is finished the exposure of film.
The utility model is simple in structure, uses black-film during exposure, only needs operating personnel promptly can finish exposure processing, and film and circuit board contraposition are accurate, are a kind of saving material and human resources, the welding resistance graph exposure film of being convenient to operate.
Claims (2)
1. a welding resistance graph exposure film is made up of the film that is shaped on exposure region, and it is characterized in that: the edge of film is shaped on positioning through hole.
2. welding resistance graph exposure film according to claim 1 is characterized in that: described positioning through hole is positioned at four jiaos of film.
