Embodiment 1

[0025] An embodiment of the present invention provides a flexible circuit board, which can be applied to electronic devices, especially small electronic devices such as mobile phones, tablet computers, and smart wearable devices.

[0026] Such as figure 1 As shown, a package area 100 of components is provided on the flexible circuit board, and a pad 101 is provided in the package area 100 . After the components are packaged on the flexible circuit board, they can be connected to other circuits in the flexible circuit board through the pads 101 .

[0027] A main trace 102 and a secondary trace 103 connected to the pad 101 are also arranged on the flexible circuit board. One end of the secondary wiring 103 is connected to the pad 101 , and the other end of the secondary wiring 103 is connected to the main wiring 102 , so that a part of the secondary wiring 103 and the main wiring 102 are connected in parallel. In this embodiment, a secondary wiring 103 is provided on one side ...

Embodiment 2

[0033] An embodiment of the present invention provides a flexible circuit board, which can be applied to electronic devices, especially small electronic devices such as mobile phones, tablet computers, and smart wearable devices.

[0034] Such as figure 2 As shown, a package area 200 of components is provided on the flexible circuit board, and a pad 201 is provided in the package area 200 . After the components are packaged on the flexible circuit board, they can be connected to other circuits in the flexible circuit board through the pads 201 .

[0035] A main trace 202 and a secondary trace 203 connected to the pad 201 are also arranged on the flexible circuit board. One end of the sub-wire 203 is connected to the pad 201 , and the other end of the sub-wire 203 is connected to the main wire 202 . In this embodiment, secondary wirings 203 are provided on both sides of the main wiring 202 , so that two secondary wirings 203 are connected in parallel with a part of the main ...

Embodiment 3

[0041] Such as image 3As shown, the embodiment of the present invention provides a flexible circuit board, which is basically the same as the second embodiment, including the pad 301 disposed in the package area 300, and the main trace connected to the pad 301 through the teardrop processing 304 process 302 , and both sides of the main routing 302 are provided with secondary routings 3031 and 3032 . The difference between the present embodiment and the second embodiment is that the lengths of the secondary traces 3031 and 3032 arranged on both sides of the main trace 302 in this embodiment are different.

[0042] When the length of the secondary trace is increased, it can continue to ensure the connection between the pad and other circuits when the main trace is disconnected in a larger range, so the longer the length of the secondary trace, the better. However, in actual wiring, the wiring spaces on both sides of the main wiring are often different. Therefore, in this embo...

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible circuit board and electronic equipment. Background technique [0002] With the continuous development of electronic technology, electronic devices such as mobile phones, tablet computers, and smart wearable devices are becoming smaller and thinner, and continue to develop towards miniaturization. [0003] Flexible printed circuit (FPC for short) is an important component in small electronic devices such as mobile phones. The flexible circuit board is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the base material. It has high wiring density, light weight, thin thickness, and good bendability. features. For example, in mobile phones, the use of flexible circuit boards with light weight and thin thickness can effectively save the volume of mobile phones, and easily connect batteries, microphones and other components into o...
