Problems solved by technology

[0002] At present, when installing a flexible printed circuit (FPC), it is often necessary to install it manually, because manual operation is easy to bring in electrostatic interference, or some components of the flexible circuit board, such as the connecting seat It is easy to cause static interference when plugging and other operations
When the above-mentioned electrostatic interference cannot be introduced to the ground for elimination in time, the electrostatic interference signal will propagate to the signal lines on the flexible circuit board, causing interference to electronic components (such as the main chip) and signal lines on the flexible circuit board, cause the signals affecting the flex board to function properly

Abstract

A flexible circuit board (100), comprising: a first face (10) and a second face (20) which are disposed opposite to each other, wherein the first face (10) comprises a first ground region (11) and a first exposed copper region (12) disposed at the edges of the periphery of the first ground region (11); a plurality of ground holes (121) are provided in the first exposed copper region (12); the plurality of ground holes (121) are respectively provided along the extension direction of the first exposed copper region (12), and all extend from the first exposed-copper region (12) to the second face (20) so as to be used in grounding. By means of the described structure, during installation, grounding characteristics of the ground holes (121) may be harnessed in a timely manner to introduce electrostatic interference from external or surrounding areas of the flexible circuit board (100) into a ground plane, preventing the electrostatic interference from being brought into internal signal lines or cross-talking to other wired circuits, thus ensuring smooth operations of signal lines and other wired circuits. Also provided is a mobile terminal (1) having the same flexible circuit board (100).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a flexible circuit board and a mobile terminal. Background technique [0002] At present, when installing a flexible printed circuit (FPC), it often needs to be installed manually. Due to the manual operation, it is easy to bring in electrostatic interference, or some components of the flexible circuit board, such as the connection seat, are assembled, welded, pulled out. It is easy to cause electrostatic interference when plugging and other operations. When the above-mentioned electrostatic interference cannot be introduced to the ground for elimination in time, the electrostatic interference signal will propagate to the signal line on the flexible circuit board, causing interference to the electronic components (such as the main chip) and the signal line on the flexible circuit board. Causes the signals affecting the flexible circuit board to operate normally. In addition, since...
