Abstract

The invention discloses a flexible circuit board. The flexible circuit board comprises a substrate, a conductive layer and a coverage layer, wherein the conductive layer is arranged on the substrate in a lamination way and comprises a first conductive sheet, a second conductive sheet and a conductive lead, the conductive lead is connected between the first conductive sheet and the second conductive sheet, and the coverage layer is arranged at one side, deviating from the substrate, of the conductive layer and is used for protecting the conductive layer. The invention also discloses a mobile terminal. The conductive lead is used for connecting the first conductive sheet and the second conductive sheet of the flexible circuit board, the bending effect of the flexible circuit board is improved, the bending radius is small, and bending at a large angle can be achieved; and the resistance of the conductive lead can be controlled by changing the cross section of the conductive lead, the bending effect of the flexible circuit board is favorably improved, the space occupied by the flexible circuit board in the mobile terminal is reduced, and the electrical connection effect of the flexiblecircuit board is further favorably improved.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a flexible circuit board and a mobile terminal. Background technique [0002] A flexible printed circuit (FPC) is made of a flexible substrate and has the characteristics of small size, light weight, and bendability, and is widely used in various types of electronic devices. A flexible circuit board generally includes a non-bending part and a bending part between the non-bending parts. When a flexible circuit board is used in electronic devices such as mobile terminals, the non-bending part is connected to the main board, display panel or For devices such as touch panels, the bending part is flexible and bendable, and the flexible circuit board can meet the space requirements inside the mobile terminal by folding the bending part. [0003] The bending part generally uses conductive materials such as copper to realize the electrical connection between the connecting en...
