In the present embodiment, the thickness of the second fixture block 200 is smaller, and then causes the second pinching end 210 insertion capacitance plate 310 and flexible circuit When between plate 320 so that the deformation of flexible PCB 320 is smaller, avoids flexible PCB 320 from being made because bending angle is excessive Damaged into flexible PCB 320.

In order to further avoid flexible PCB 320 from causing flexible PCB 320 to damage because bending angle is excessive, example Such as, the thickness of second fixture block 200 is 1mm~8mm, for example, the thickness of second fixture block 200 is 1mm~5mm, for example, The thickness of second fixture block 200 is 1.8mm, and in the present embodiment, the thickness of the second fixture block 200 is smaller, and then causes the second folder After between tight the insertion capacitance plate 310 of end 210 and flexible PCB 320 so that the deformation of flexible PCB 320 is smaller, further Flexible PCB 320 is avoided to cause flexible PCB 320 to damage because bending angle is excessive.It should be understood that the second folder The thickness of block 200 can not be too small, and the thickness of the second fixture block 200 is too small, then hardness then reduces, and is unfavorable for flexible PCB 320 Force, therefore, in the present embodiment, the thickness of the second fixture block 200 is 1mm~5mm, i.e., flexible PCB 320 can be avoided excessive Deformation, cause the second fixture block 200 that there is stronger hardness again, flexible PCB 320 can be pressed well.

In order that two opposite surfaces of flexible PCB 320 can be fully connected to by obtaining the second stitching surface 211 so that Flexible PCB 320 can be overlayed fully on test board, for example, the stop section 140 is raised in first stitching surface 111 Thickness be less than second fixture block 200 thickness, for example, the stop section 140 is raised in the thickness of first stitching surface 111 Degree is less than 3mm, for example, the thickness that the stop section 140 is raised in first stitching surface 111 is less than 2mm, for example, the gear The thickness that stop 140 is raised in first stitching surface 111 is 0.5mm~2mm, for example, the stop section 140 be raised in it is described The thickness of first stitching surface 111 is 1.5mm, it should be understood that the thickness of stop section 140 can not be too small, the thickness of stop section 140 Degree is too small can not then to carry out block positioning, and the thickness of stop section 140 can not be too big, too to flexible PCB 320 well It is big then will cause the second stitching surface 211 be connected to stop section 140 and be obstructed, fully flexible PCB 320 can not be overlayed and surveyed On test plate (panel), therefore, in the present embodiment, the stop section 140 be raised in the thickness of first stitching surface 111 for 0.5mm~ 2mm, on the one hand, can effectively prevent the second stitching surface 211 by block, then cause the second stitching surface 211 fully by flexible circuit Plate 320 is overlayed on test board, on the other hand, then to play flexible PCB 320 good block positioning action.

In order to preferably be guided to flexible PCB, for example, the first stitching surface offers guiding groove, for example, described Guiding groove is by the end of the one end of first stitching surface away from first connecting hole towards the direction of first connecting hole Open up, i.e. the opening of the guiding groove is arranged at the end of the one end of the first stitching surface away from first connecting hole, and guiding groove End is then close to the first connecting hole, for example, the test board is arranged in the guiding groove, for example, the stop section is arranged at The end of the guiding groove, so, after the second pinching end of the second briquetting inserts capacitance plate and called in the following text between FPC, Flexible PCB slides along guiding groove in guiding groove, and the both sides of guiding groove limit flexible PCB and positioned, flexible electrical Road plate is connected to the stop section of the end of guiding groove and stopped, and then enables flexible PCB accurate alignment test board, makes Obtain flexible PCB to be efficiently and accurately connected with test board, and then improve testing efficiency.

In order that flexible PCB can be fully connected to by obtaining the second stitching surface, for example, the depth of the guiding groove is less than 3mm, for example, the depth of the guiding groove is less than 2mm, for example, the depth of the guiding groove is 0.5mm~2mm, for example, described The depth of guiding groove is 1.2mm, and in the present embodiment, the depth of guiding groove is smaller so that flexible PCB is at least partly raised in The top of guiding groove so that the second stitching surface can fully be connected to flexible PCB, and then flexible PCB is filled Point stress is overlayed on test board, further, since guiding groove has certain depth, can be well to the fortune of flexible PCB It is dynamic to be limited, and block so that flexible PCB can efficiently and accurately align test board, and then improve testing efficiency.
