Abstract
The utility model is related to a kind of flexible PCB, the flexible PCB includes substrate diaphragm flexible, is arranged in several plain conductors of the basilar memebrane on piece, the cover film of a part of plain conductor of covering and the edge part i.e. golden finger for exposing the plain conductor；Wherein, the side of the golden finger is provided with for crimping the mark point being directed toward.The utility model is provided with mark point by the side in golden finger, has achieved the effect that improve the accuracy of contraposition and the success rate of crimping；By cutting slot so that each golden finger is independent, is reached during crimping, golden finger can fully with the effect of not destroying panel while plate contact.
Description
Technical field
The utility model is related to a kind of flexible PCBs, belong to circuit board making technical field.
Background technology
Flexible circuit board is a kind of high reliability and flexible printed circuit board, abbreviation soft board, with Distribution density
Feature high, light-weight, thickness is thin is mainly used in mobile phone, laptop, palm PC PDA, digital camera, liquid crystal
Show in the products such as module LCM.In liquid crystal display panel industry now, the crimping of liquid crystal display panel mostly uses flexible PCB and panel
Contact crimping, but in existing technology, crimping success rate is low.
Utility model content
The purpose of this utility model is to provide one kind can improve crimping success rate, it is simple in structure, during crimping
The flexible PCB of protection panels.
In order to achieve the above objectives, the utility model provides the following technical solutions：A kind of flexible PCB, the flexible circuit
Several plain conductors, a part of metal of covering that plate includes substrate diaphragm flexible, is arranged in the basilar memebrane on piece are led
The cover film of line and the edge part, that is, golden finger for exposing the plain conductor；Wherein, the side of the golden finger, which is provided with, is used for
Crimp the mark point being directed toward.
Further, the mark point is cross structure.
Further, it is additionally provided between the golden finger and independent cuts slot for separating to become the golden finger.
The beneficial effects of the utility model are：Side in golden finger is provided with mark point, has reached raising pair
The effect of the accuracy of position and the success rate of crimping；
By cutting slot so that each golden finger is independent, is reached during crimping, and golden finger can fully and face
Plate does not destroy the effect of panel while contact.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.
Description of the drawings
Fig. 1 is the single unit system structure chart of the flexible PCB of the utility model.
Fig. 2 is the part-structure schematic diagram in Fig. 1.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Refer to Fig. 1, the flexible PCB in a preferred embodiment of the utility model include substrate diaphragm 1 flexible,
The cover film of several plain conductors (not shown), a part of plain conductor of covering for being arranged on the substrate diaphragm 1 is (not
Diagram) and expose edge part, that is, golden finger 3 of the plain conductor.In the present embodiment, the golden finger 3 is distributed in described soft
The one side edge of property circuit board, the both ends at the edge of the flexible PCB are all provided with golden finger 3.Really, in other implementations
In example, the golden finger 3 can also be distributed in the other positions of the flexible PCB, depending on actual conditions.
Fig. 2 is referred to, is provided in the side of the golden finger 3 for crimping the mark point 2 being directed toward, the mark point 2
For cross structure, the mark point 2 will not have an impact the function of the golden finger 3 far from the golden finger 3.The mark
Note point 2 is cross structure, all has sense of touch up and down, improves the accuracy of crimping.It is additionally provided with use between the golden finger 3
In by the golden finger 3 separate become it is independent cut slot 31, after cutting slot 31, each golden finger 3 is independent, in the mistake of crimping
Cheng Zhong, can be with independent deformation as probe, sufficient and plate contact, but panel table will not be broken as probe
Face plays the effect of protection panels.
The production method of the flexible PCB of the present embodiment is as follows：
Continuous metal carbonyl conducting layer is deposited on the substrate diaphragm 1, and on continuous metal line layer after resist coating,
Several plain conductors detached are exposed, develop and etched successively, and a part of plain conductor is covered with mask.
In summary：By being provided with mark point 2 in the side of golden finger 3, the accuracy and pressure for improving contraposition are reached
The effect of the success rate connect；
By cutting slot 31 so that each golden finger 3 is independent, is reached during crimping, golden finger 3 can be abundant
With the effect for not destroying panel while plate contact.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
