[0002] At present, the FPC board of the backlight module needs to be welded with the FPC board of the display screen. In the related technology, a double-layer FPC board is usually used, and then the pads on the FPC board of the display screen are routed to ensure that the pads on the FPC board and the gold fingers are on the same plane, so as to facilitate the welding of the FPC board of the backlight module with the pads. However, the cost of using a double-layer board is not only high, but also increases the thickness. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an FPC welding structure, which can reduce the cost and reduce the thickness of the FPC board.
[0004] The purpose of this utility model is achieved through the following technical solutions:
[0005] The first aspect of the present application provides an FPC welding structure, comprising: an FPC board; a bending component, the bending component comprising a bump, an adhesive portion and a soldering pad, the bump being arranged on the FPC board, the adhesive portion being arranged on the bump, the soldering pad being arranged on the bump away from the adhesive portion, a connecting portion being arranged on the bump, the bump being bent along the connecting portion toward the FPC board so that the adhesive portion adheres to the FPC board.
[0006] It also includes a positioning component, which includes a first marking line and a second marking line. The first marking line and the second marking line are both arranged on the FPC board, and the first marking line and the second marking line are perpendicular to each other.
[0007] The surface area of the adhesive portion is smaller than or equal to the surface area of the bump.
[0008] It also includes a binding end, which is arranged on the FPC board.
[0009] It also includes a plug-in terminal, which is arranged on the FPC board.
[0010] The protrusion is also provided with a first side edge, and the first side edge is used to overlap with the first marking line after the protrusion is bent along the connecting portion toward the FPC board.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0022] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0023] At present, the FPC board of the backlight module needs to be welded with the FPC board of the display screen. In the related technology, a double-layer FPC board is usually used, and then the pads on the FPC board of the display screen are routed to ensure that the pads on the FPC board and the gold fingers are on the same plane, so as to facilitate the welding of the FPC board of the backlight module with the pads. However, the cost of using a double-layer board is not only high, but also increases the thickness.
[0024] In view of the above problems, an embodiment of the present application provides an FPC welding structure, which can reduce costs and reduce the thickness of the FPC board.
[0025] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0026] See also Figure 1 and Figure 2 A FPC welding structure includes: an FPC board 100 and a bending component 200, the bending component 200 includes a bump 210, an adhesive portion 220 and a pad 230, the bump 210 is arranged on the FPC board 100, the adhesive portion 220 is arranged on the bump 210, the pad 230 is arranged on the bump 210 away from the adhesive portion 220, and a connecting portion 211 is arranged on the bump 210. The bump 210 is bent along the connecting portion 211 toward the FPC board 100 so that the adhesive portion 220 adheres to the FPC board 100.
[0027] It should be noted that the adhesive part 220 is double-sided adhesive. Before welding, the bump 210 is first bent along the connecting block toward the FPC board 100 until the adhesive part 220 adheres to the FPC board 100. Since the pad 230 is arranged opposite to the adhesive part 220, after bending, the pad 230 can be directly on the same plane as the binding end 400 on the FPC board 100. The above method can be achieved by using a single-layer FPC board, which reduces the cost and also reduces the overall thickness of the FPC board 100.
[0028] See also Figure 1In one embodiment, an FPC welding structure further includes a positioning assembly 300, the positioning assembly 300 includes a first marking line 310 and a second marking line 320, the first marking line 310 and the second marking line 320 are both arranged on the FPC board 100, and the first marking line 310 and the second marking line 320 are perpendicular to each other. Specifically, a first side edge 212 is also arranged on the protrusion 210, and the first side edge 212 is used to overlap with the first marking line 310 after the protrusion 210 is bent along the connecting portion 211 toward the FPC board 100. Specifically, a second side edge 213 is also arranged on the protrusion 210, and the second side edge 213 is used to overlap with the second marking line 320 after the protrusion 210 is bent along the connecting portion 211 toward the FPC board 100.
[0029] It should be noted that by setting the first marking line 310 and the second marking line 320 , the bending position of the bump 210 on the FPC board 100 can be confirmed to prevent deviation, thereby avoiding inadequate welding of the pad 230 and the FPC board 100 of the backlight module.
[0030] See also Figure 1 In one embodiment, the surface area of the adhesive portion 220 is less than or equal to the surface area of the bump 210. It should be noted that the surface area of the adhesive portion 220 is slightly less than or equal to the surface area of the bump 210, which can ensure that the bump 210 is completely adhered to the FPC board 100 without warping.
[0031] See also Figure 2 In one embodiment, it further includes a binding end 400, which is disposed on the FPC board 100. It should be noted that the binding end 400 is a gold finger of the FPC board.
[0032] See also Figure 1 In one embodiment, the FPC board 100 further includes a plug-in terminal 500, which is disposed on the FPC board 100. It should be noted that the plug-in terminal 500 is used to plug into the host.
[0033] See also Figure 1 In one embodiment, a reinforcing member 600 is further included, and the reinforcing member 600 is disposed on the FPC board 100. It should be noted that the reinforcing member 600 can be adhesive tape or other parts that increase mechanical strength, and its role is to enhance the mechanical strength of the FPC board 100.
[0034] See also Figure 1 In one embodiment, an arc structure 211a is provided on the connecting portion 211. It should be noted that by providing the arc structure 211a, the bending stress can be reduced to prevent the bump 210 from warping after bonding.
[0035] See also Figure 1In one embodiment, a chamfered portion 214 is further provided on the bump 210. It should be noted that by providing the chamfered portion 214, the surface of the bump 210 can be made smoother to prevent people from accidentally touching and scratching.
