FPC (flexible circuit board) is that have height reliability using polyimides or polyester film as one kind made of substrate,
Excellent flexible printed circuit has the characteristics that Distribution density is high, light-weight, thickness is thin.
Currently, FPC (flexible circuit board), which is widely used in hanger, carries out electro-coppering production, but existing hanger for copper electroplating
There are copper-plated uniformity is poor, as shown in Figure 1, flexible circuit board folder is hung on hanger 1, since there are frames 10 for hanger 1
And cause the spacing between the flexible circuit board on flexible circuit board and another hanger larger, it is affected by edge effect,
During being electroplated, since the frame 10 on hanger can also generate power line, (power line is the illusory of field distribution
Directing curve race), but the power line that frame 10 generates does not form plating circuit, so results in it to the soft of formation plating circuit
Property circuit board 2 draw close so that the edge surrounding current density of flexible circuit board 2 is larger, the side of the flexible circuit board 2 after making plating
The copper facing of edge position is thicker, not only reduces copper-plated uniformity in this way, it is also possible to cause to make in lower current density
Used time, the edge of flexible circuit board is easy to burn phenomenon because of current convergence, to cause scrapping for product.Therefore, existing
Some FPC plate hanger for copper electroplating are also wait there is improved space.
Utility model content

The mobile jib is that axis is formed with the first support end and the second support end, and first support end and the second support end are respectively arranged with
For clamping the clamp of FPC plate, the surface of the interconnecting piece, support rod and clamp is provided with encapsulated layer.
Further, the frame is PP frame.
Further, the clip for being convenient to clamp FPC plate is additionally provided on the PP frame.
Further, the hook for hanging up hanger is additionally provided on the mobile jib.
Further, the FPC plate is copper foil.
Further, the encapsulated layer is Teflon glue.
Further, the surface of the mounting portion is provided with the fine copper for improving conductive stability.
Further, the material of the mobile jib and the support rod is 316 stainless steels.
Compared with prior art, the utility model has the beneficial effects that:
The utility model eliminates the included frame of hanger, utilizes the included side of the frame substitution hanger for placing FPC plate
Frame realizes product and product zero distance, the influence of edge effect is preferably minimized with during plating, so that flexible circuit
The uniform current density of the edge surrounding of plate, to realize the operability of current density.
