Flexible printed circuit board and mobile terminal

Abstract

The invention provides a flexible printed circuit board and a mobile terminal. The flexible printed circuit board comprises a substrate layer, a copper foil layer and a covering membrane. The copper foil layer is arranged on the substrate layer. The copper foil layer comprises two oppositely arranged non-bending parts and a strip-shaped bending part connected between the non-bending parts. Conductive wires are arranged on the non-bending parts. The bending part is of a winding structure. A bending conducive wire is arranged on the bending part and is bent along with the bending part. One end of the bending conductive wire is connected to the conductive wires. The covering layer is laminated on the copper foil layer, and covers the bending part and the non-bending parts. When the overall length of the flexible printed circuit board is not increased, bending flexibility is improved, stress of the bending part is also reduced and flexibility of the bending part of the flexible printed circuit board is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a flexible circuit board and a mobile terminal.
