The embodiment of the application provides a flexible circuit board and electronic equipment, which are used for reducing the risk that the flexible circuit board and a signal wire inside the flexible circuit board are broken due to bending.
As shown in fig. 1, which is a schematic structural diagram of a flexible circuit board in the prior art, the flexible circuit board in fig. 1 includes: a first connection end 101, a second connection end 102, and a bent portion 103. The bending portion 103 is disposed between the first connection end 101 and the second connection end 102, the bending portion 103 includes a signal line 202, an insulating layer 203, and a protection layer 201, the insulating layer 203 wraps the signal line 202, the protection layer 201 wraps a whole formed by the signal line 202 and the insulating layer 203, and a length of the signal line 202 in an unstressed state is equal to a length of the bending portion 103. Since the length of the signal line 202 in the unstressed state is equal to the length of the bending part 103 (i.e. the width of the bending part 103), the signal line can only be stretched at this length when bending, and therefore, after the flexible circuit board is bent for a plurality of times, the signal line 202 is at risk of breaking due to the stretching/bending of the signal line 202 for a plurality of times, thereby resulting in a risk of poor contact and even failure of the components connected by the signal line.
In order to reduce the risk of breaking the signal line 202, the present application provides a new flexible circuit board, please refer to fig. 2, fig. 3, and fig. 4, where fig. 2 is a schematic structural diagram of the flexible circuit board provided in the embodiment of the present application, fig. 3 is a cross-sectional view of the flexible circuit board provided in the embodiment of the present application, and fig. 4 is a schematic perspective structural diagram of the flexible circuit board provided in the embodiment of the present application. As shown in fig. 2, fig. 3, and fig. 4, the flexible circuit board provided in the embodiment of the present application includes: a first connection end 101, a second connection end 102, and a bent portion 103.
The bending part 103 is disposed between the first connection end 101 and the second connection end 102, the bending part 103 includes at least one flexible circuit board main body and a protection layer 201, the flexible circuit board main body includes a signal line 202 and an insulation layer 203 wrapping the signal line 202, the protection layer 201 wraps the at least one flexible circuit board main body, wherein the signal line 202 includes at least one first signal line, and the length of the first signal line in an unstressed state is greater than the length of the bending part 103.
As shown in fig. 2, the first connection terminal 101 and the second connection terminal 102 are provided with signal lines in addition to the bent portion 103. Since the signal lines provided in the first connection terminal 101 and the second connection terminal 102 are not bent/stretched, the material of the signal line in this region may be the same as or different from that of the signal line in the bent portion 103, for example, the signal line in this region may be an electrodeposited copper foil, a forged rolled copper foil, or the like; the signal line in this region may be formed in a "twisted" shape so that its length is longer than the length of normal straightening, or may be formed in a "straight" shape so that its length is maintained at the length of normal straightening, or the like.
In the embodiment of the present application, in order to satisfy a certain stretching performance of the flexible circuit board at the bending portion 103, a portion of the signal line in the middle of the flexible circuit board needs to be designed into a "twisted" shape (for example, "S" shape) in an unstressed state, and in addition, the signal line can also be designed into other shapes, only the length of the portion of the signal line in the unstressed state is required to be greater than the length of the bending portion 103 (i.e., the width of the bending portion), so that it can be ensured that the signal line 202 in the flexible circuit board can be stretched with a sufficient length when being bent, and the signal line 202 is not stretched at the same length as the bending portion 103 as the signal line 202 in fig. 1, so as to cause the signal line 202 to be pulled and broken. It should be noted that, although it is not described in the present application that all signal lines are designed to be "twisted" or in other shapes, according to actual needs, all signal lines of the bending portion 103 may be designed to be "twisted" or in other shapes, and the length of all signal lines in an unstressed state is ensured to be greater than the length of the bending portion 103, so that the signal line 202 can have a sufficient length to shrink along with the bending of the flexible circuit board when the flexible circuit board is bent, and can be shortened when folded, and can be lengthened when stretched, so as not to be broken after being stretched for multiple times, which may cause poor contact or even failure of other components connected to the signal line 202.
In an embodiment of the present application, the material of the first signal line includes a rolled copper foil. Generally, a signal line of a flexible circuit board generally adopts a copper conductor, and the copper conductor is generally divided into two types of electrodeposition molded copper foil and forged rolled copper foil.
In the embodiment of the present application, the shape of the insulating layer 203 surrounding the first signal line matches the shape of the first signal line. For convenience of showing the position relationship between the first signal line and the insulating layer 203, please refer to fig. 4, fig. 4 is a schematic perspective view of the flexible circuit board provided in the present application, and as can be seen from fig. 4, the insulating layer 203 is wrapped outside the first signal line, and the shape thereof matches with the shape of the first signal line, that is, the insulating layer 203 should be wrapped according to the shape of the first signal line. In addition, the insulating layer 203 is made of an insulating material that is not conductive at a certain voltage, such as insulating varnish, insulating paste, fabric, rubber, plastic, and products thereof, to avoid interference between signal lines, wherein the material of the insulating layer may be at least one of silicon nitride (SiNx) and silicon oxide (SiOx).
In the present application, since the first signal line is provided in the bent portion 103 and represents only a part of the signal lines 202 of the bent portion 103, not all the signal lines, the length, shape, material, positional relationship with the insulating layer 203, and the like of the first signal line are applied only to a part of the signal lines. However, the first signal line may be extended to all signal lines in the bending portion 103 according to actual conditions, and the length, shape, material, and positional relationship with the insulating layer 203 of the first signal line may be applied to all signal lines in the bending portion 103 of the flexible circuit board.
In the present embodiment, the protective layer 201 is a stretchable flexible material, such as rubber or the like. Specifically, the material of the protective layer 201 may include at least one of polyimide, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyarylate, and polyethersulfone. The protection layer 201 is provided to prevent the signal line 202 and the insulating layer 203 from being broken during the bending process, and covers the signal line 202 and the insulating layer 203 to protect the signal line 202 and the insulating layer 203 and improve the overall bending/stretching performance of the flexible circuit board.
In the embodiment of the present application, the signal lines are arranged at equal intervals, that is, the arrangement intervals between the signal lines are equal.
It should be noted that fig. 2 is only a schematic structural diagram of the flexible circuit board, not an entire structural diagram, and the structure of the flexible circuit board in the non-bent state is as shown in fig. 4, which is a flat plane, and fig. 2 is a schematic structural diagram of the flexible circuit board after being bent. All other structures that can be obtained by a person skilled in the art without making creative efforts based on the structures in the present application belong to the protection scope of the present application.
When the flexible circuit board passes through the middle of the rotating shaft and the rotating shaft cover of the bending area of the electronic device, the bending area is compact, and the flexible circuit board can be pulled and continuously deformed in the bending process, so that the flexible circuit board has the risk of breaking after being bent for a certain number of times, and the components connected through the flexible circuit board also have the risk of poor contact and even failure, and finally the electronic device has the problems of poor contact and the like.
