In a preferred embodiment of the present utility model, the angle of described chamfering is 30 °.
In a preferred embodiment of the present utility model, the described second cylindrical diameter is 3.175mm.
In a preferred embodiment of the present utility model, the described first cylindrical diameter is 6mm, and thickness is 0.1mm.
Compared to prior art, the orientation tool of the wiring board green oil exposure alignment of doing over again of the present utility model can reduce the operation easier of the plate exposure manual alignment of doing over again, greatly improve precision and the efficient of manual alignment, finally realize the advantage maximization of green oil Manual exposure, shortcoming minimizes.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the do over again tangent plane structural drawing of orientation tool one preferred embodiment of wiring board green oil exposure alignment of the utility model;
Fig. 2 is the use view of orientation tool shown in Figure 1 when being used for doing over again the wiring board green oil exposure alignment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1, the utility model discloses a kind of orientation tool of the wiring board green oil exposure alignment of doing over again, described orientation tool comprises the first right cylinder 1 and the second right cylinder 2, and the diameter of described the first right cylinder 1 is greater than the diameter of described the second right cylinder 2.Described the first right cylinder 1 and described the second right cylinder 2 are stainless steel, and both axis overlaps, and the structure of described orientation tool be it seems as "T"-shaped from sectional drawing, that is to say, described the first right cylinder 1 be connected the second right cylinder 2 and vertically connect.
Wherein, described the first right cylinder 1 is cap structure, and its top is chamfering, and the angle of described chamfering is 30 °.In the present embodiment, the diameter of described the first right cylinder 1 is preferably 6mm, and thickness is preferably 0.1mm.
Described the second right cylinder 2 is the rivet nut structure, and its bottom margin is the right angle, and in the present embodiment, the diameter of described the second right cylinder 2 is preferably 3.175mm, and length is preferred.Wherein, the design that the bottom of described the second right cylinder 2 makes the right angle is intended to improve aligning accuracy, second film can not come off together with the other end that wiring board is enclosed within described the second right cylinder 2 simultaneously, thereby improves the efficient of operation, and is as described below in detail.
See also Fig. 2, when described orientation tool was used for doing over again the wiring board green oil exposure alignment, its concrete steps operation was as follows:
1, utilizes puncher to go out four diameters for the circular hole 6 of 3.175mm at first film 3 and second film 4 four jiaos according to plate face position of positioning hole, that is to say that the diameter of the circular hole 6 of going out equals the diameter of the second right cylinder 2;
2, orientation tool is inserted from the reverse side of first film 3 in four jiaos the circular hole 6, the first right cylinder 1 exposes in the outside of circular hole 6, and the second right cylinder 2 is fixed on the first right cylinder 1 on first film 3 with single face glue in circular hole 6;
3, utilize four jiaos of wiring board 5 respectively to have a diameter also to be the pilot hole 9 of 3.175mm, the second right cylinder 2 is inserted in pilot hole 9, the position of the circular hole 6 that pilot hole 9 and first film 3 and second film are 4 four jiaos is corresponding, the size coupling;
4, the front with 4 four jiaos of second films is enclosed within on the second right cylinder 2, and the film face of the maintenance of the bottom of preferred the second right cylinder 2 and second film 4 is on the same level face, and namely the thickness of the thickness of the second right cylinder 2 and wiring board 5 is complementary;
5, the front of second film 4 is bonding with double faced adhesive tape and wiring board 5, the purpose in this step is to guarantee not walk when first circuit board film exposure, can tear when second wiring board exposure;
6, stick respectively Double-face gummed paper 7 at four edges of the reverse side of first film 3 and second film 4, after the two sides contraposition was finished, the mode that wiring board 5 is being pasted glass table top according to the first right cylinder 1 was sent into manual exposure machine and is vacuumized exposure;
7, first circuit board film exposure finished, under the state of board without vacuum, first film 3 and second film 4 are because reverse side posts double faced adhesive tape 7, therefore will glue respectively on the Mayla frame and glass table top of staying exposure machine, the tear double faced adhesive tape 8 of second film 4 and wiring board 5 adhesions, this moment is sticking first film 3 and the supporting alignment about in the of 4 of second film of staying on Mayla frame and the glass table top respectively, and is whole as a mould;
8, will glue respectively first film 3 and second film, the 4 usefulness single face glue stayed on Mayla and the glass table top and fix from the edge, guarantee that first film 3 and second film 4 are not shifted;
9, since second wiring board, the principle according to wiring board line alignment and film coupling can directly be pressed into wiring board in the second right cylinder 2, directly enters the manual exposure machine exposure.
Compared to prior art, the beneficial effect of the orientation tool of the wiring board green oil exposure alignment of doing over again of the present utility model is:
