Problems solved by technology

Since the medium of the flexible circuit board is very thin and relatively soft, when the pad cannot be reinforced and protected, the FPC is not hard enough, and the pad on the FPC is easily pierced by the shrapnel contact, which will cause the device and the back of the pad to be disconnected. The network causes a short circuit

Abstract

The invention provides a flexible circuit board which comprises a dielectric layer, two wiring layers and pads. The dielectric layer comprises a first surface and a second surface which is arranged oppositely to the first surface. The two wiring layers are respectively arranged on the first surface and the second surface. The pads are arranged on the first surface and are connected with electronic components. The second surface is provided with a supporting cushion at a position which faces the pads. Furthermore the orthographic projections of the pads are on the supporting cushion. The supporting cushion is separated from the wiring layer on the second surface. No signal is inputted into the supporting pad, or the signal attribute of the supporting pad is same with that of the pad.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a flexible circuit board and a mobile terminal. Background technique [0002] At present, with the rapid development of mobile communication technology and the improvement of hardware system performance, existing terminals such as tablet computers and mobile phones have compact structures, thin and light appearances, and circuit board layouts have also become compact. For example, in existing designs, electronic devices such as terminal interface devices or terminal edge layout sensing devices mostly adopt partial modular design, and will be connected to the main board through a flexible circuit board (FPC, Flexible Printed Circuit) or use a flexible circuit board as the main board. The sub-board to carry the electronic components. Since the medium of the flexible circuit board is very thin and relatively soft, when the pad cannot be reinforced and protected, the FPC is n...
