Abstract
The utility model discloses a kind of flexible PCB, comprises nation fixed end, and described nation fixed end comprises individual layer district, and described individual layer district comprises cabling district and non-cabling district, and described non-cabling district is provided with circular hole.The utility model, by arranging small sircle hole in non-cabling district, can reduce the stress that flexible circuit board nation fixed end produces because of bending, thus not affect the display effect of IPS screen, substantially increase product quality.
Description
Technical field
The utility model relates to circuit board technology field, particularly relates to a kind of flexible PCB.
Background technology
Flexible PCB is that the one made for base material with polyimides or polyester film has height reliability, excellent flexible printed circuit.Be called for short soft board or FPC (Flexible Printed Circuit, flexible PCB), have the advantages that distribution density is high, lightweight, thickness is thin, bending property is good.At present, flexible PCB is widely used in the electronic products such as mobile phone, notebook computer, panel computer, digital camera.
IPS (In-Plane Switching, plane conversion) screen has been widely used on mobile phone, HDTV as current state-of-the-art display device.In these Product Assembly processes; usually the nation fixed end of IPS screen will be connected after the fixed end bending of FPC golden finger nation by conducting film; due to certain stress can be produced after FPC bending, the display effect of IPS screen can be affected when stress is larger, edge, IPS screen nation fixed end usually can be made to whiten and show.Stress refers under external force, can produce interactional internal force in deformable body between particle, and the internal force of unit are is called stress.
Therefore, how to avoid affecting IPS Showing Effectiveness On Screen because of FPC bending, become the technical problem that prior art is badly in need of solving.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of flexible PCB, and it can realize not affecting IPS Showing Effectiveness On Screen after nation's fixed end bending.
For solving technical problem of the present utility model, the utility model discloses a kind of flexible PCB, comprises nation fixed end, and described nation fixed end comprises individual layer district, and described individual layer district comprises cabling district and non-cabling district, and described non-cabling district is provided with circular hole.
Wherein, described Circularhole diameter is 5 to 7 millimeters.
Wherein, described non-cabling district comprises multiple equally distributed circular hole.
Compared with prior art, the utility model has following beneficial effect: the utility model is by arranging small sircle hole in non-cabling district, the stress that flexible circuit board nation fixed end produces because of bending can be reduced, thus do not affect the display effect of IPS screen, substantially increase product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flexible PCB of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, be the flexible circuit board structure schematic diagram of the utility model one embodiment.Flexible PCB of the present utility model comprises nation fixed end 10, and nation fixed end 10 comprises individual layer district 20 (shown in dotted line), and individual layer district 20 comprises the first cabling district 21 and the second cabling district 22 and non-cabling district 23.Usual individual layer district refers to the region only having one deck to connect up, and namely cabling district refers to the region having wiring, and non-cabling district is the region without cabling in individual layer district except cabling district.
Cabling district can arrange multiple according to actual conditions, the size in non-cabling district is also different accordingly.In the utility model embodiment, be evenly distributed with 9 circular holes 24 in non-cabling district 23, diameter is 6 millimeters.Those skilled in the art can according to the actual size in non-cabling district, and arrange the circular hole of respective numbers, diameter range is advisable to 7 millimeters at 5 millimeters.
In sum, the utility model, by arranging small sircle hole in non-cabling district, can reduce the stress that flexible circuit board nation fixed end produces because of bending, thus not affect the display effect of IPS screen, substantially increase product quality.
More than lift preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc.; all should be included within protection range of the present utility model; the interest field that the utility model is advocated should be as the criterion described in utility model application scope, but not is only limitted to above-described embodiment.
Claims (3)
