The invention relates to a flexible circuit board and an electronic device. The flexible circuit board comprises a circuit board main body and a pressure-sensitive color developing layer. One side of the circuit board main body is provided with a plurality of golden fingers which are arranged at intervals along a first direction, and the other opposite side of the circuit board main body is provided with a silk-screen white line which extends lengthwise along the first direction; the pressure-sensitive color developing layer is arranged on the silk-screen white line, the pressure-sensitive color developing layer is configured to respond to pressure applied to the pressure-sensitive color developing layer to be converted into a color developing state from an initial color state, in the initial color state, the pressure-sensitive color developing layer presents a first color, and in the color developing state, the pressure-sensitive color developing layer presents a second color different from the first color. According to the flexible circuit board, the problems that the loosening reason of the flexible circuit board and the connector is difficult to quickly determine at present, and the working efficiency of searching for the loosening reason is low can be solved.
Description
technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to flexible circuit boards and electronic equipment. Background technique [0002] Flexible printed circuit board (Flexible Printed Circuit, FPC) is a kind of flexible printed circuit board made of polyimide or polyester film as the base material, and the flexible circuit board is connected with other components through connectors, specifically A gold finger is arranged on the flexible circuit board, and the electrical connection and signal transmission are realized through the gold finger between the flexible circuit board and the connector. Among them, the connection between the plug-in gold finger and the connector is to insert the gold finger part of the flexible circuit board into the slot of the connector. If the connection between the flexible circuit board and the connector becomes loose, the gold finger and the connection There are many reasons for the loose...
