Flexible circuit formed on surface cloth and preparation method thereof

The invention provides a flexible circuit formed on surface cloth and a preparation method thereof. The method comprises the following steps: S1, respectively adhering and fixing an upper polymer film layer and a lower polymer film layer on the upper surface and the lower surface of a conductive metal foil to form a composite conductive film material; S2, placing the composite conductive film material below cutting equipment, cutting according to a circuit diagram to form a conductive circuit, and fixing an electronic element on the conductive circuit; and S3, respectively adhering and fixing an upper cloth layer and a lower cloth layer on the upper surface and the lower surface of the conductive circuit. The flexible circuit has the advantages that the flexible circuit is not provided with the substrate layer and the protective layer which are formed by the polymer film on the upper surface and the lower surface, so that the flexible circuit is relatively soft and has a soft and non-inductive effect after be
