Through the double-side communicated design in positions of the golden fingers, the utility model ensures the wire communication between the golden fingers and the liquid crystal display module assemblies during welding, and improves the product yield in the processing process of the liquid crystal display module assemblies.
Description
Technical field
The utility model relates to a kind of flexible print circuit board device, and the flexible print circuit board architecture advances that in particular a kind of liquid crystal display module is used is used for the protection of liquid crystal display module course of processing flexible print circuit board welding ends and uses.
Background technology
In the prior art, be the needs that reduce cost, the connected mode of liquid crystal display module and system changes to some extent, and the connected mode that is about to special connector has changed the flexible print circuit board welding manner into.
Because the flexible print circuit board (FPC, Flexible Printed Circuit) of welding manner is with low cost, reliability height during use, thereby product cost can reduce.But with respect to former connector contact connected mode, the connected mode of FPC also has shortcoming; be that it is not because the welding ends golden finger has the PI diaphragm to cover (polyimides; Polyimide is called for short PI), and in the course of processing, cause circuit bad easily because bend.
In the course of processing, and in the processes such as welding, the operation of doing over again, because flexible print circuit board may be bent, thereby cause the welding circuit at golden finger position to be fractureed, thereby cause the product yield to descend.As shown in Figure 1, the used for flexible printed circuit board that is prior art needs to bend FPC in the golden finger position of welding owing in the course of processing, left comer 110 as shown in Figure 1, and circuit easily fractures at welding 111 places, saturating tin hole.In addition,, because to the bending of FPC, may cause having the circuit 121 of the face 120 of stretching to fracture in when welding, shown in Fig. 2 a and Fig. 2 b, these all can cause the decline of product yield.
Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide a kind of liquid crystal display module flexible print circuit board, improves the syndeton of its golden finger position, the conduction property of FPC circuit when guaranteeing welding.
The technical solution of the utility model comprises:
A kind of liquid crystal display module flexible print circuit board, it comprises that one is used for the golden finger weld part with the liquid crystal display mode bond pads, this golden finger weld part is provided with a plurality of golden finger bars that are used to weld, wherein, the upper end of each golden finger bar is provided with a through hole, and conduction connects the corresponding golden finger bar of described golden finger weld part both sides.
Described liquid crystal display module flexible print circuit board, wherein, described through hole is covered by the PI diaphragm.
Described liquid crystal display module flexible print circuit board, wherein, described golden finger weld part two edges side is provided with the wide stiffener of more described golden finger bar, covers copper sheet on this stiffener, and on this copper sheet layer the PI cover layer is set.
Described liquid crystal display module flexible print circuit board, wherein, described stiffener is parallel to the setting of golden finger bar.
A kind of liquid crystal display module flexible print circuit board provided by the utility model, by double-side conduction design in the golden finger position, guarantee golden finger and the liquid crystal display module line conduction when welding, improved the yield of product in the liquid crystal display module course of processing.
Description of drawings
Fig. 1 is the FPC golden finger partial schematic diagram of the liquid crystal display module production process of prior art;
Fig. 2 a and Fig. 2 b are the FPC golden finger schematic diagram that opens circuit that bending may cause when welding of prior art;
Fig. 3 a and Fig. 3 b are that FPC golden finger line construction of the present utility model improves schematic diagram;
Fig. 4 a and Fig. 4 b are that the FPC golden finger line construction of the utility model second preferred embodiment improves schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, will be described in more detail each preferred embodiment of the present utility model.
Liquid crystal display module of the present utility model flexible print circuit board 200, shown in Fig. 3 a and Fig. 3 b, it is at golden finger weld part 210 places with the liquid crystal display mode bond pads of being used for of prior art, a plurality of golden finger bars 211 that are used to weld are set, the golden finger bar is provided with tin hole 212, simultaneously, be provided with a through hole 213 in the upper end of each golden finger bar 211, the corresponding golden finger coating in the both sides of described golden finger weld part 210 extends through this through hole 213 conduction connection mutually, thus each other as backup.When in the course of processing, when described FPC is bent, there is the one side of stretching may be, and, therefore still can guarantees the operate as normal of described FPC owing to there is the backup of opposite side to connect by the circuit that fractures.Thus, the yield in the process of producing product can be improved, and can prolong the useful life of product.
For strengthening the panel toughness of liquid crystal display module described in the utility model, PI diaphragm cover layer 214 is arranged in described through hole 213 arranged outside with flexible print circuit board.
Simultaneously; for preventing that FPC fractures from the golden finger weld part in the course of processing; be provided with the wide stiffener 221 of more described golden finger bar at described liquid crystal display module with the described golden finger weld part 210 two edges sides of flexible print circuit board; shown in Fig. 4 a; continue with reference to figure 4b; on this stiffener 221, be coated with copper sheet 222; and on this copper sheet layer 222, PI cover layer 223 is set; so; when in the course of processing; when the utility model liquid crystal display module is bent with flexible print circuit board; described stiffener 221 and covering copper sheet 222 and PI cover layer 223 on it have strengthened hardness and toughness; do the time spent when being subjected to external force, the golden finger that can disperse to greatest extent to expose bends power, protects it to exempt from and fractures.Described stiffener 221 can be parallel to described golden finger bar 211 and be provided with, and described golden finger weld part 210 can be stretched out and widen setting; Certainly, as a kind of embodiment of the present utility model, the setting of described stiffener 221 is can be diversified, and nonessential parallel and described golden finger bar 211 is provided with.
The utility model liquid crystal display module flexible print circuit board, by upper end at the welding golden finger, increase the mode of a through hole, kept the golden finger bar circuit of described golden finger weld part upper and lower surface all to extend to through hole, and through hole is covered by the PI cover layer, comparatively firm, thereby make the corresponding golden finger bar circuit of two sides form backup, when one side fractures because of tensile force, or welding scolding tin connects when unreliable, other end circuit still can play the conducting effect, has so improved to be close to one times reliable life.
In the sampling test that liquid crystal display module described in the utility model carries out at present with flexible print circuit board; the utility model technique scheme has been improved the cabling circuit; can play the effect of protecting welding ends well, and a large amount of before this bad phenomenon such as fracture that occur seldom occur.Therefore, technical solutions of the utility model have beneficial effect preferably, and its improvement is comparatively simple.
Should be understood that above-mentioned description at the utility model preferred embodiment is comparatively concrete, can not therefore think the restriction to the utility model scope of patent protection, scope of patent protection of the present utility model should be as the criterion with claims.
