AI Technical Summary
[0002]目前在显示模组行业中，采用ZIF插接形式的FPC上，通常会在FPC的插接处设置丝印线来辅助判断是否插接到位，但是设置丝印线的方式只适用于FPC的插接处是金手指面朝下的结构，如果遇到FPC的插接处是金手指面朝上上，由于金手指处无法设置丝印线，而丝印线如果设置在背面则会无法观察到，因此对于FPC的插接处是金手指面朝上的结构时，容易出现没有对位而导致操作人员用力过当导致金手指断裂的问题，而断裂位置往往是金手指的缩腰位置处
[0008]采用上述方案，本实用新型的有益效果在于：设置蚀刻形成的第一标记和第二标记，不仅可以提高插接位置的对位精度，并且可以提升ZIF插接部的抗弯折强度，无需增加成本，有提升可靠性和作业效率。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and in particular to an FPC with a ZIF plug-in structure. Background Technology
[0002] Currently in the display module industry, FPCs using ZIF connectors typically have silkscreen lines at the connector points to help determine if they are properly connected. However, this method only works when the gold fingers face down at the connector point. If the gold fingers face up, silkscreen lines cannot be placed there, and if placed on the back, they will be invisible. Therefore, when the gold fingers face up at the connector point, misalignment can easily occur, leading to excessive force from the operator and breakage of the gold fingers. The breakage often occurs at the constricted area of the gold fingers.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an FPC with a ZIF plug-in structure.
[0005] The technical solution of this utility model is as follows: This utility model provides an FPC with a ZIF plug structure, including: an FPC body, the FPC body including a ZIF plug portion, a plurality of gold fingers formed on the ZIF plug portion, a first mark for alignment formed at the left and right edges of the plug portion, a second mark for improving the bending resistance of the plug portion formed inside the first mark of the ZIF plug portion, the second mark corresponding to the waist of the gold fingers of the plug portion in the length direction, the first mark and the second mark are both formed by etching the copper layer of the FPC.
[0006] Furthermore, the width of the second mark is greater than or equal to 0.2 mm.
[0007] Furthermore, the width of the second mark is 0.25 mm.
[0008] The beneficial effects of this utility model by adopting the above solution are as follows: setting the first and second marks formed by etching can not only improve the alignment accuracy of the insertion position, but also improve the bending strength of the ZIF insertion part, without increasing the cost, and improve reliability and work efficiency. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0010] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0011] Please see Figure 1 , Figure 1 The dashed line in the middle indicates the location of the waistline of the two types of gold fingers. In this embodiment, the present invention provides an FPC with a ZIF plug structure, including: an FPC body (not marked), the FPC body including a ZIF plug portion 1, a plurality of gold fingers formed on the ZIF plug portion 1, and first marks 2 for alignment formed at the left and right edges of the plug portion. During insertion, the relative position of the first marks 2 and the inserted ZIF plug can be directly judged. A second mark 3 for improving the bending resistance of the plug portion is formed inside the first mark 2 of the ZIF plug portion 1. The width of the second mark 3 is 0.25mm. Both the first mark 2 and the second mark 3 are formed by etching the copper layer of the FPC. The length direction of the second mark 3 corresponds to the waist of the gold fingers covering the plug portion. It is worth noting that the waist of the ZIF plug portion 1 refers to the position where the gold fingers of the ZIF plug portion 1 change in line width closest to the edge of the cover film. At this position, due to the change in line width and the insertion force, the chain breakage problem is likely to occur. The second mark 3 can increase the copper-clad area to increase the bending resistance.
[0012] In summary, the beneficial effects of this solution are as follows: setting the first and second marks formed by etching can not only improve the alignment accuracy of the insertion position, but also enhance the bending strength of the ZIF insertion part, without increasing costs, and improve reliability and work efficiency.
[0013] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
