Wherein, the thickness of described circuit board body is 0.05-0.18mm；The a length of 20-25mm of described long side；The a length of 7-9mm of described anti-tear band.
Wherein, the thickness of described circuit board body is 0.06mm；The a length of 22.8mm of described long side；The a length of 8.02mm of described anti-tear band.
Wherein, the bending angle of described kink is 15-25 °.
Wherein, described side is outwards bent to form described kink.
Wherein, the bending angle of described kink is 19 °.
The beneficial effects of the utility model are: the anti-tear band being different from prior art FPC circuit board is linear type, the deficiency of anti-tear poor effect；This utility model, by extending the length of anti-tear band, increases the protection domain at edge；Anti-tear band is set simultaneously there is certain bending angle; can the kink of covering board body side, to being easiest to occur the kink of tear to protect, it is achieved thereby that the anti-tear function of FPC board edge; strengthen the protection to FPC board edge, reduce the fraction defective of product.

Detailed description of the invention
By describing technology contents of the present utility model in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained.
The design of this utility model most critical is: extends the length of anti-tear band on circuit board body edge, meanwhile, makes tear-strap cover kink, it is achieved the lifting of the anti-tear intensity of board edge.
Refer to Fig. 1 and Fig. 2, this utility model provides a kind of FPC circuit board preventing marginal laceration, including circuit board body 1 and anti-tear band 2；The side 3 of described circuit board body 1 is provided with anti-tear band 2, and the side 3 of described circuit board body 1 has kink 4, and described anti-tear band 2 covers described kink 4 and arranges.
Knowable to foregoing description, the beneficial effects of the utility model are: as it is shown in figure 1, the anti-tear band 2 of prior art is straight line, and anti-tear band 2 length L1 is 4.01mm, anti-tear poor effect.This utility model, by extending the length of anti-tear band 2 on circuit board side 3, expands the scope of anti-tear protection；Meanwhile, side is easiest to occur the kink 4 of tear situation to cover and described anti-tear band 2 is set, it is possible to kink 4 is protected；It is achieved on the premise of not changing circuit board thickness, is obviously improved the anti-tear performance of board edge, optimize the structure of circuit board product, improve the yields of product.
Further, described circuit board body 1 is strip, including two short sides 6 and two long sides 5, is provided with the long side 5 that side 3 is described circuit board body 1 of described anti-tear band 2.
Seen from the above description, FPC circuit board product of the present utility model is strip, and long side 5 is provided with kink 4; by kink 4 is carried out anti-tear protection; realize the anti-tear performance that circuit board product is overall, improve the yields of this product, optimize customer experience.
Further, the thickness of described circuit board body 1 is 0.05-0.18mm；The a length of 20-25mm of described long side 5；The a length of 7-9mm of described anti-tear band 2.
