Abstract
The utility model discloses a flexible circuit board hollow-out golden finger adhesive pasting structure. Golden finger areas among each terminal are hollow-out areas. A cushion layer is covered over the whole golden finger area. An adhesive layer above the cushion layer is covered over the whole golden finger area and pasted on a flexible circuit board or a portion which the adhesive layer can be pasted on. By employing the flexible circuit board hollow-out golden finger adhesive pasting structure, adhesive pasting and adhesive tearing are convenient and quick and not subjected to adhesiveness restriction of the adhesives; if adhesiveness of the adhesives is strong, the golden finger is not dragged during adhesive tearing; and if the adhesiveness of the adhesives is weak, a pasting portion is not influenced as adhesive liquid leakage does not occur, so the golden finger is effectively protected.
Description
Technical field
The utility model relates to a kind of FPC hollow out golden finger rubberizing structure and sticking method, belongs to electronic technology field.
Background technology
Golden finger mainly is intended for the externally outlet of communication of wiring board on the FPC, by the gold with superior electrical conductivity and non-oxidizability the golden finger place is carried out parcel plating or chemical turmeric, and the connection of golden finger is extremely important to FPC.In order not influence the characteristic of golden finger, in some processing steps, must apply protection to golden finger.Usually the method that adopts is to protect in golden finger surface rubberizing, still, it is torn glue bother very much; Especially for FPC, form Openworks shape between each golden finger line, if the viscosity of rubberizing is stronger with hollow out golden finger; When tearing glue; The golden finger line is easily by the viscosity of glue and distortion is pullled in adhesion, even broken string; If the viscosity of rubberizing a little less than, then paste imprecision, lose the protective effect of rubberizing.
The utility model content
The utility model technical problem to be solved provides a kind of FPC hollow out golden finger rubberizing structure and sticking method, makes rubberizing, tears the glue more convenient and quicker, not limited by the viscosity of glue, does not pull golden finger when tearing glue, effectively the protective money finger.
For solving the problems of the technologies described above; The utility model provides a kind of FPC hollow out golden finger rubberizing structure, comprise FPC and on golden finger, it is characterized in that; Between each terminal of said golden finger region is vacancy section, on the whole zone of said golden finger, covers a bed course; One glue-line covers said golden finger zone across said bed course, and is pasted on the FPC or the position of Pasting glue-line.
The area of said bed course is not less than said golden finger zone.
The area of said glue-line is greater than the area of said bed course.
Sticking method based on the described hollow-out flexible circuit board gold of claim 1 finger plaster plastic structure is characterized in that, comprises following steps:
(1) on the whole zone of golden finger, covers a bed course;
(2) said golden finger zone is covered across said bed course with a glue-line,
(3) and be pasted on the FPC said glue-line or the position of Pasting glue-line.
Preferably, the area of said bed course is not less than said golden finger zone.
Preferably, the area of said glue-line is greater than the area of said bed course.
Preferably, be vacancy section between regional each terminal of said golden finger.
The beneficial effect that the utility model reached:
The FPC hollow out golden finger rubberizing structure and the sticking method of the utility model; Make rubberizing, tear the glue more convenient and quicker, not limited by the viscosity of glue, tear glue when adhesivity is strong and can not pull golden finger; The liquid medicine seepage influence position of pasting can not take place in adhesivity when weak, effectively protected golden finger.
Description of drawings
Fig. 1 is the utility model FPC hollow out golden finger sketch map;
Fig. 2 is the rubberizing structural representation of Fig. 1;
Fig. 3 is the right view of Fig. 2 rubberizing structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection range of the utility model with this.
As shown in Figure 1, be vacancy section 22 between golden finger zone 2 each terminal 21 on the FPC 1, this hollow out golden finger more is prone to pullled distortion.Therefore, like Fig. 2, shown in Figure 3, the sticking method of present technique scheme is at first covering a bed course 3 on golden finger zone 2, and bed course 3 is not with the common interlayer of glue, can be with golden finger zone 2 whole coverings.On bed course 3, paste a glue-line 4 again, glue-line 4 areas are greater than bed course 3, can be coated on it down with bed course 3 is whole, and be pasted on the FPC or other positions 5.Because of the isolation of bed course 3, glue-line 4 can not paste golden finger zone 2, thereby has avoided golden finger zone 2 each terminal 21.When tearing glue, glue-line 4 can not pullled golden finger zone 2 each terminal 21.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection range of the utility model.
Claims (3)
1. FPC hollow out golden finger rubberizing structure, comprise FPC and on golden finger, it is characterized in that, be vacancy section between each terminal of said golden finger region, on the whole zone of said golden finger, cover a bed course; One glue-line covers said golden finger zone across said bed course, and is pasted on the FPC or the position of Pasting glue-line.
2. FPC hollow out golden finger rubberizing structure according to claim 1 is characterized in that, the area of said bed course is not less than said golden finger zone.
3. FPC hollow out golden finger rubberizing structure according to claim 1 is characterized in that the area of said glue-line is greater than the area of said bed course.
