Detailed Description

As shown in fig. 1 and 2, a normal FPC fixing state when the ACF is attached to the FPC is shown, where the FPC100 includes gold finger portions 110, first wire array portions 130, element integration portions 120, and second wire array portions 140, and the first wire array portions 130 connect the gold finger portions 110 and the element integration portions 120. Since the thickness of the component integration part 120 is thicker than other parts, the electrical contact surface of the gold finger part 110 must be upward, and the side of the component integration part 120 where electronic components are integrated must also be upward, when the FPC is placed on the console 300, the first wire arrangement part 130, the second wire arrangement part 140, and the gold finger part 110 are all in a suspended state, and it is difficult to attach the ACF. Even if the vacuum suction device is provided on the stage 300 to suck the component integrated parts 120, it is difficult to fix and adhere the first and second wire arrangement parts 130 and 140 and the gold finger parts 110 to the surface of the stage 300. Therefore, it is generally necessary to attach the ACF by pressing the remaining portion while attaching the first and second bus bar portions 130 and 300 to the surface of the stage using the tape 200. Such a method is cumbersome and inefficient, and tends to damage the FPC when the tape 200 is stuck and removed. Therefore, a scheme is needed to improve the work efficiency of attaching the ACF to the FPC and reduce the risk of damaging the FPC.

The utility model provides an FPC (flexible printed circuit) attaching jig for attaching an ACF (anisotropic conductive film), which comprises: a base plate; an element sliding groove; the component sliding groove is suitable for the component integration part of the FPC to slide along the component sliding groove; a flat cable sliding groove; the flat cable sliding groove is suitable for the flat cable part of the FPC to slide along the flat cable sliding groove; the limiting part is suitable for blocking the FPC from moving to one side of the element sliding groove; the blocking part is suitable for blocking the wire arranging part of the FPC from moving up and down in the vertical direction when the FPC slides to one side; and the air exhaust hole is suitable for adsorbing the wire arranging part on one side of the golden finger part of the FPC. The FPC attaching jig for attaching the ACF can improve the operation efficiency of attaching the ACF to the FPC and reduce the hidden trouble of FPC damage.
