Description

Technical Field

[0001] The utility model relates to the technical field of FPC, in particular to an FPC splicing structure. Background Art

[0002] In order to facilitate product traceability, electronic products will require the addition of a QR code on the FPC of the display module. This QR code is bound to the production batch and date production process of each material and processing step of the product.

[0003] The existing solution for adding QR codes is as follows (eg Figure 1 ): Because the current FPC cover film is yellow, that is, the appearance of the manufactured FPC product is also yellow, so it is necessary to first screen print a layer of white oil block on the double-layer area of ​​the FPC, and then spray print a layer of black QR code on the white oil block. This structure needs to increase the thickness, and the printed white oil block area will also have uneven thickness problems, resulting in poor recognition of the QR code printed on the upper end, and it is not easy to scan the code.

[0004] In order to solve the above technical problems, Chinese invention patent: CN 113891570 A discloses a processing method for improving the uniformity of character white oil blocks, which belongs to the technical field of PCB board processing and printing. The processing method for improving the uniformity of character white oil blocks includes: using a jet printer to print a white oil block area with a thickness of 10 to 50 μm on the PCB board; using the jet printer to print ink on the concave part in the white oil block area, and controlling the amount of ink printed according to the depth of the concave part to make the white oil block area flat; applying photosensitive paste on a text printing net, the text printing net adopts a specification of 90 to 140T, exposing the text printing net to develop a two-dimensional code pattern, and obtaining a printing plate with a two-dimensional code pattern; using the printing plate to screen print the two-dimensional code pattern on the white oil block area, the screen printing speed is controlled at 300 to 700 mm / s, and the screen printing pressure is controlled at 3 to 7 kg / cm2; and the white oil block area is dried. The disclosed "processing method for improving the uniformity of character white oil blocks" uses a jet printer to print white oil blocks, firstly printing the ink on the PCB, and then immediately curing the ink.

[0005] However, since the ink has no time to flow and fill, if there is an uneven area at the bottom of the character white oil block, the white oil block will appear uneven after printing, and the QR code will be easily scratched after printing, resulting in unclear or incomplete QR code on the white oil block, affecting production efficiency.

[0015] Furthermore, the FPC substrate has a side edge with an anti-strange corner, and the anti-strange corner is located on a side edge of any of the screw holes.

[0016] Furthermore, the FPC single particle includes a rectangular end and a long strip end, the rectangular end is provided with a long strip connecting portion, and the long strip end is provided with two forked first connecting portions and a second connecting portion.

[0030] Embodiment 1

[0031] For background technology, please refer to Figure 1 At present, the covering film of FPC is yellow, that is, the appearance of the manufactured FPC product is also yellow. Therefore, it is necessary to first screen print a layer of white oil block on the double-layer area of ​​​​the FPC, and then spray print a layer of black QR code on the white oil block. This structure needs to increase the thickness, and the printed white oil block area will also have uneven thickness problems, resulting in poor recognition of the QR code printed on the upper end, and it is not easy to scan the code.

[0032] In order to solve this technical problem, the utility model provides a FPC panel structure, such as Figure 2 and Figure 4As shown, an FPC panel structure comprises: an FPC substrate 1, on which a plurality of FPC particles 2 are arranged, and the FPC particles 2 are arranged opposite to each other in pairs and embedded in the FPC substrate 1; a two-dimensional code area is provided at the edge of the FPC substrate 1, and a copper foil 12 is exposed at the bottom of the two-dimensional code area; a white two-dimensional code 3, and the white two-dimensional code 3 is sprayed on the copper foil 12, wherein the FPC substrate 1 comprises a substrate 11, and copper foil 12 is provided on both sides of the substrate 11, and copper deposits 13 are provided on the sides of the two copper foils 12 away from each other, and a covering film 14 is provided on the sides of the two copper deposits 13 away from each other, wherein the white two-dimensional code 3 is sprayed on the side of one of the copper foils 12 away from the substrate 11 with white ink.

[0033] In the present application, the QR code area on the FPC substrate 1 is hollowed out downward to expose the copper foil 12. Taking advantage of the fact that the exposed copper foil 12 is easily oxidized and its color turns red and black, a layer of white QR code 3 is directly sprayed on this QR code area, which can form a sharp contrast with the surrounding colors, making it easy to scan and identify the code, without adding a layer of white oil block, thus reducing the process flow and reducing costs.

[0034] It should be noted that the QR code is a graphic that is distributed in a plane according to a certain pattern using certain specific geometric figures. In code compilation, the concept of "0" and "1" bit streams that constitute the internal logic basis of the computer is cleverly used, and several geometric shapes corresponding to binary are used to represent textual numerical information. It is automatically read through image input devices or photoelectric scanning devices to realize automatic information processing: it has some common features of bar code technology: each code system has its own specific character set; each character occupies a certain width; it has certain verification functions, etc. It also has the function of automatically identifying information in different rows and processing graphic rotation change points.

[0035] In this embodiment, the cover film 14 and the copper deposition 13 on one side are provided with hollowing at the same position, and the hollowing forms a two-dimensional code area.

[0036] Through the above-mentioned structural design, the covering film 14 and the copper plating 13 of the area where the two-dimensional code needs to be added can be hollowed out while the whole board circuit is being manufactured, and this area can be etched out without affecting the production efficiency. At this time, there is no need to add a layer of white oil block. It is only necessary to directly print the white two-dimensional code 3 on the copper foil 12 to form a sharp contrast with the surrounding colors. This can solve the problem that the silk-screen white oil block in the prior art will increase the thickness, and the printed white oil block area will also have uneven thickness, resulting in poor recognition of the two-dimensional code printed on the upper end and difficulty in scanning.

[0037] Furthermore, the hollow setting can also prevent the painted QR code from being scratched and peeling off, which can better ensure the clarity and integrity of the QR code.

[0038] Embodiment 2

[0039] The FPC panel structure provided in the first embodiment is further optimized. Specifically, Figure 2 As shown, the FPC substrate 1 is provided with screw holes 4 for positioning and maintaining the stability of the FPC substrate 1 .

[0040] Specifically, there are four screw holes 4, which are respectively arranged at four corners of the FPC substrate 1. Through the above structural design, the screw holes 4 are used to position the FPC substrate and maintain the stability of the position of the FPC substrate 1.

[0041] In this embodiment, an anti-strange corner 5 is provided on the side of the FPC substrate 1 , and the anti-strange corner 5 is located on the side of any of the screw holes 4 .

[0042] Through the above structural design, the anti-stuck angle 5 is used to limit the placement direction of the FPC substrate 1, so that the FPC substrate 1 can be placed in the correct direction, so that the process can proceed smoothly.

[0043] Embodiment 3

[0044] like Figure 2 and Figure 3 As shown, the FPC single particle 2 includes a rectangular end and a long strip end. The rectangular end is provided with a long strip connecting portion 21, and the long strip end is provided with two forked first connecting portions 22 and second connecting portions 23.

[0045] In a further preferred embodiment of the present invention, two FPC particles 2 form a group, wherein the long strip connecting portion 21 of one FPC particle 2 is aligned with the second connecting portion 23 of another FPC particle 2 .

[0046] Through the above structural design, the outer edges of the two FPC single particles 2 are staggered, and the long strip connecting portion 21 of one FPC single particle 2 is aligned with the second connecting portion 23 of the other FPC single particle 2, so that the structures therebetween will not interfere with each other. In the FPC layout, the two FPC single particles 2 are arranged in a group of combined arrays in the FPC substrate 1, which can well increase the internal space utilization rate of the FPC substrate 1. The FPC single particles 2 are provided with rectangular ends and long strip ends, and the rectangular structure formed by splicing two by two reduces the waste space in the middle, thereby achieving more products produced from the raw materials per unit area, reducing the unit price cost of the products, and reducing waste.

[0047] In a further preferred solution of this embodiment, the FPC substrate 1 can accommodate four groups of two FPC particles 2 arranged in a combination.

[0048] Through the above structural design, the FPC substrate 1 has good accommodation capacity and can accommodate four groups of two FPC single particles 2 arranged together, thereby making maximum use of the interior of the FPC substrate 1 .

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
