Description
Technical field
The present invention relates to a kind of flexible PCB, belongs to circuit board making technical field.
Background technology
FPC is a kind of printed circuit board (PCB) of high reliability and pliability, and abbreviation soft board, it has Distribution density
The characteristics of high, in light weight, thickness of thin, it is mainly used in mobile phone, notebook computer, palm PC PDA, digital camera, liquid crystal
Show in the products such as module LCM.In liquid crystal panel industry now, the crimping of liquid crystal panel, use flexible PCB and panel more
Contact crimping, but in existing technology, crimping success rate is low.
The content of the invention
It is an object of the invention to provide one kind can improve crimping success rate, it is simple in construction, protect during crimping
The flexible PCB of panel.
To reach above-mentioned purpose, the present invention provides following technical scheme：A kind of flexible PCB, the flexible PCB bag
The substrate diaphragm for including flexibility, several plain conductors being arranged on the substrate diaphragm, cover a part of plain conductor
Cover layer 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 of sensing.
Further, the mark point is cross structure.
Further, it is additionally provided between the golden finger and becomes independent for the golden finger to be separated and cut groove.
The beneficial effects of the present invention are：Mark point is provided with by the side in golden finger, has reached and has improved contraposition
The effect of accuracy and the success rate of crimping；
By cutting groove 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.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Brief description of the drawings
Fig. 1 is the single unit system structure chart of the flexible PCB of the present invention.
Fig. 2 is the part-structure schematic diagram in Fig. 1.
Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Fig. 1 is referred to, the flexible PCB in a preferred embodiment of the invention includes flexible substrate diaphragm 1, set
Several plain conductors (not shown), the cover layer of a part of plain conductor of covering on the substrate diaphragm 1 (are not schemed
Show) and expose the edge part i.e. golden finger 3 of the plain conductor.In the present embodiment, the golden finger 3 is distributed in the flexibility
One lateral edges of circuit board, the both ends at the edge of the flexible PCB are all provided with golden finger 3.Really, in other embodiment
In, 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 with the side of the golden finger 3 for crimping the mark point 2 pointed to, the mark point 2
For cross structure, the mark point 2 will not have an impact away from the golden finger 3 to the function of the golden finger 3.The mark
Note point 2 is cross structure, all has sense of touch up and down, improves the degree of accuracy of crimping.Use is additionally provided between the golden finger 3
Become independent in the golden finger 3 is separated and cut groove 31, after cutting groove 31, each golden finger 3 is independent, in the mistake of crimping
Cheng Zhong, deformation that can be independent as probe, sufficiently and plate contact, but panel table will not be broken as probe
Face, serve the effect of protection panels.
The preparation 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 separated 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 groove 31 so that each golden finger 3 is independent, is reached during crimping, golden finger 3 can be abundant
Effect with not destroying panel while plate contact.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply 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, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
Claims (3)
1. a kind of flexible PCB, it is characterised in that the flexible PCB includes flexible substrate diaphragm, is arranged on the base
The cover layer of several plain conductors, a part of plain conductor of covering on bottom diaphragm and the edge for exposing the plain conductor
Portion is golden finger；Wherein, the side of the golden finger is provided with for crimping the mark point pointed to.
