Abstract
The utility model relates to a there is flexible wiring board who presses thin finger of screen, shielding thin finger including the circuit board with pressing, pressing the carefully equal parallel and level of finger top tip of screen, a water flat line is arranged into to the extreme point, and the perpendicular distance between the water flat line and gate board top edge is 0.1 millimeter. The utility model provides high screen finger tip to the size precision of position mark width between centers that presses avoids the FPC shaping to press the screen and point carefully that stick up or the roughness defect is shielded to short circuit, pressure that the off normal arouses, has avoided the burr problem because of the die -cut production of mould simultaneously.
Description
Technical field
The utility model relates to circuit board structure field, particularly relates to a kind of flex circuit application having the thin finger of pressure screen.
Background technology
FPC flex circuit application is connected by pressing to shield carefully to point with LCM glass, when making this wiring board, direct mould points stamping-out out by thin for pressure screen usually at present, but along with the raising required, usual requirement carefully point top to the distance tolerance at alignment mark center to control to ± 0.1 millimeter, even some company tolerance is brought up to ± 0.075 millimeter, thin finger end is strict to bad requirements such as burrs simultaneously, for reaching control overflow, must in the punching of pressure screen thin finger both sides design target, and adopt precision die stamping-out to press the thin finger of screen, cause the increase of production cost, and the risk of short circuit after easily there is pressure screen, even if like this, also be difficult to produce the product that tolerance is ± 0.075 millimeter.
In prior art, if the patent No. is 201120039853.8, the applying date is 2011.02.16 " ITO that the back side increases reinforcement carefully points ", and this utility model provides the ITO of the back side increase reinforcement that a kind of plate face is smooth, finger span is stable carefully to point, and can be widely used in mobile phone production field.But this utility model still cannot solve the problem of the pressure screen easy off normal of thin finger and shaping difficulty, and easily produce burr, cause conforming product rate to reduce, production cost is high, is further improved.
Utility model content
For the present situation of above-mentioned prior art, it is simple that technical problem to be solved in the utility model is to provide a kind of structure, and practical value is high, effectively improves the flex circuit application of dimensional accuracy.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of flex circuit application having the thin finger of pressure screen, comprise wiring board and the thin finger of pressure screen, wiring board two ends are respectively arranged with the first telltale mark and the second telltale mark, it is characterized in that: the end points of described pressure screen thin finger upper end is arranged in a horizontal line, and the vertical range between described horizontal line and wiring board top edge is 0.1 millimeter.
Compared with prior art, the utility model has the advantage of: the utility model improves the dimensional accuracy of pressure screen finger end to telltale mark centre distance, avoid the shaping pressure screen short circuit that carefully finger warps or off normal causes of FPC, pressure screen evenness defect, avoid because the Burr Problem of the die-cut generation of mould simultaneously.
Accompanying drawing explanation
Fig. 1 is circuit board structure figure of the present utility model;
Fig. 2 is that pressure of the present utility model screen carefully points schematic diagram.
Embodiment
As shown in Figure 1-2, a kind of flex circuit application having the thin finger of pressure screen, comprise wiring board 1 and the thin finger 2 of pressure screen, wiring board 1 two ends are respectively arranged with the first telltale mark 12 and the second telltale mark 13; The thin finger of pressure screen 2 upper end are all concordant, and end points is arranged in a horizontal line 21, and horizontal line 21 and wiring board 1 top edge 11 are parallel to each other, and the vertical range between horizontal line 21 and wiring board 1 top edge 11 is 0.1 millimeter.
The distance on the pressure thin finger end of screen and profile limit is inside contracted 0.1 millimeter by the utility model, the distance inside contracting rear pressure screen finger end and the first telltale mark 12 center can be controlled by graphic designs, do not need to ensure with mould, even if tolerance ± 0.075 millimeter, can ensure yet.The utility model improves the dimensional accuracy of pressure screen finger end to telltale mark centre distance, avoids the shaping pressure screen short circuit that carefully finger warps or off normal causes of FPC, pressure screen evenness defect, avoids because the Burr Problem of the die-cut generation of mould simultaneously.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
Claims (1)
1. one kind has the flex circuit application of the thin finger of pressure screen, comprise wiring board and the thin finger of pressure screen, wiring board two ends are respectively arranged with the first telltale mark and the second telltale mark, it is characterized in that: the end points of described pressure screen thin finger upper end is arranged in a horizontal line, and the vertical range between described horizontal line and wiring board top edge is 0.1 millimeter.
