This FPC is provided with an anti -tear line and the 2nd anti -tear line respectively at the positive and negative of the regional department of turning round, and can strengthen FPC and in the intensity of regional department of turning round, prevent that FPC from being torn in the regional department of turning round, and an anti -tear line and the 2nd anti -tear line can effectively stop the further expansion of crack when the crack appearing, it is regional to prevent that the crack from spreading the circuit.
Description
Technical field
The utility model is related to wiring board art, more particularly to a kind of FPC, LED lamp bar and backlight.
Background technology
FPC（FPC）It is a kind of flexual printed circuit board (PCB) with height reliability, with Distribution density
The characteristics of high, lightweight, thickness of thin, it is mainly used in numerous products such as mobile phone, notebook computer, PDA, digital camera, LCM
In.But, the position in the region of turning round of FPC is easily torn, so that the copper cash of circuit is exposed outside in FPC.
In liquid crystal display module, just occur that short circuit is existing when FPC exposed copper cash contacts with the brandreth of backlight
As burning out FPC.Sometimes tear edge is spent greatly, and the copper cash of circuit causes FPC to scrap even directly by tear fracture in FPC.This is all
The defect of traditional FPC structures, especially current large area backlight demand is more and more, in order to increase module intensity, typically can use
Brandreth is wrapped up, while in order to the needs of radiating, FPC can be attached on brandreth, causing FPC to connect directly with brandreth, as long as FPC mono- is torn
Split and expose copper cash and will be short-circuited.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of FPC, LED lamp bar and backlight.Should
Positive and negatives of the FPC at region of turning round is respectively arranged with the first anti-tear line and the second anti-tear line, can strengthen FPC and turn round
Intensity at region, prevents FPC to be torn at region of turning round, and the first anti-tear line and the second anti-tear line can
When there is slight crack, effectively stop the further expansion of slight crack, prevent slight crack from spreading to land.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of FPC, the FPC include region of turning round, and the front in the region of turning round is provided with the first anti-tear line, and its is anti-
Face is provided with the second anti-tear line.
Further, the stepped construction of the FPC includes successively the first diaphragm, the first Copper Foil, base material, the second Copper Foil and the
Two diaphragms, the first anti-tear line and the second anti-tear line are separately positioned on first diaphragm and base material and second
Between diaphragm and base material.
Further, the described first anti-tear line and the second anti-tear line are staggered.
Further, the described first anti-tear line and the second anti-tear line are copper cash.
Further, first diaphragm is PI films.
Further, second diaphragm is PI films.
Further, the base material is PI films.
A kind of LED lamp bar, including above-mentioned FPC and some LED for being welded on the FPC.
A kind of backlight, including above-mentioned LED lamp bar.
The utility model has the advantages that：
（1）Positive and negatives of the FPC at region of turning round is respectively arranged with the first anti-tear line and the second anti-tear line, can
Strengthen intensity of the FPC at region of turning round, prevent FPC to be torn at region of turning round, and the first anti-tear line and the
Two anti-tear lines when there is slight crack, can effectively stop the further expansion of slight crack, prevent slight crack from spreading to land；
（2）The first anti-tear line and the second anti-tear line are in staggered distribution, and compared with distribution is overlapped, what is be in staggered distribution is flat
Tear strength is higher, and during frequently little dynamics is torn in assembling backlight obvious advantage is provided with；
（3）After having used the FPC structures, the FPC lamp bars of backlight are not easy open circuit because being torn, or exposure
Go out the Copper Foil of cabling, especially for the large area backlight with metal frame, will not contact with metal frame because of the Copper Foil of cabling
And cause short circuit, and cause LED to burn, effectively increase the safety and reliability of backlight.
Description of the drawings
The front schematic view of the FPC that Fig. 1 is provided for the utility model；
The reverse side schematic diagram of the FPC that Fig. 2 is provided for the utility model；
The stepped construction figure of the FPC that Fig. 3 is provided for the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As illustrated in fig. 1 and 2, a kind of FPC, the FPC include land and logicalnot circuit region, and the area of turning round of its cabling
There is region of turning round, the front in the region of turning round is provided with the first anti-tear line 1, and it is anti-tear that its reverse side is provided with second at domain
Line 2.
Positive and negatives of the FPC at region of turning round is respectively arranged with the first anti-tear line 1 and the second anti-tear line 2, compares
In the anti-tear line of individual layer of the prior art, intensity of the FPC at region of turning round can be strengthened, prevent FPC at region of turning round
It is torn；As FPC because external force is acted on, when being torn at region of turning round, the anti-tear line 2 of the first anti-tear line 1 and second
The further expansion of slight crack can effectively be stopped, prevent slight crack from spreading to land.
As shown in figure 3, the stepped construction of the FPC includes successively the first diaphragm 3, the first Copper Foil 4, base material 5, the second Copper Foil
6 and second diaphragm 7, the anti-tear line 2 of the first anti-tear line 1 and second is separately positioned on first diaphragm 3 and base
Between the diaphragm 7 of material 5 and second and base material 5.
The anti-tear line 2 of the first anti-tear line 1 and second is staggered.
The anti-tear line 2 of the first anti-tear line 1 and second is in staggered distribution, and compared with distribution is overlapped, what is be in staggered distribution is flat
Tear strength is higher, equivalent to there is double shielding.FPC it is actually used in, typically in frequently assembling process,
FPC is constantly artificially torn, although less still frequency is high for dynamics, the anti-tear line 2 of the first anti-tear line 1 and second
