Description

Technical Field

[0001] The utility model relates to the technical field of FPC, in particular to a mold for improving the utilization rate of FPC panel. Background Technique

[0002] The description of this part only provides background information related to the disclosure of the utility model, and does not constitute prior art.

[0003] Flexible printed circuit board (i.e., FPC, Flexible Printed Circuit board) has many advantages compared with rigid PCB board. When punching FPC panel, an FPC panel mold is required. At present, in the FPC industry, in order to improve the mold manufacturing ability, the design utilization rate of FPC panel is sacrificed, resulting in fewer PCS numbers per unit area and affecting the unit price of products.

[0004] The final forming process of FPC production will use a steel mold for punching. The mold processing is to wire-cut corresponding positioning holes, guide posts, the FPC outline to be punched, etc. on the surface of a flat steel plate. Usually, considering production efficiency, multiple pieces are punched at one time. Therefore, the distance setting between flexible circuit board pieces is the most important technical index considering the manufacturing process ability of the mold. Usually, the distance value between pieces is not less than 3mm. If it is too small, when the punch and die bite up and down during punching on a 25-ton punching machine, the FPC pieces are too close to each other, and it is extremely easy to cause the mold cavity in the middle area to deform and collapse due to the lack of metal parts support around. The mold cannot be used for punching processing for a long time. In order to ensure the punching life of the mold, it is necessary to increase the distance between FPC pieces during panel making, that is, "sacrifice" the panel utilization rate to meet the punching life requirements of the mold.

[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the utility model and facilitating the understanding of those skilled in the art.

[0012] Further, for the above-mentioned mold for improving the utilization rate of FPC panel, the number of the first punches is N, and the number of the second punches is N + 1.

[0013] Further, for the above-mentioned mold for improving the utilization rate of FPC panel, the length of the second punches along the second direction is greater than the length of the second mold along the second direction, and the distance between the two second punches farthest apart in the first direction is greater than the distance between the two side edges of the second mold.

[0014] Further, for the above-mentioned mold for improving the utilization rate of FPC panel, the second positioning hole coincides with the guide hole.

[0015] In summary, the above structure adopted in the embodiments of the present invention has the following advantages:
