Claim Text:
1. A method for manufacturing a flexible printed circuit board, comprising: providing a flexible printed circuit unit comprising a base layer and a first circuit layer formed on a surface of the base layer; providing a flexible resin coated copper, the flexible resin coated copper comprising a first insulating layer and a copper layer adhered with the first insulating layer; adhering the flexible resin coated copper with the flexible printed circuit unit, the first insulating layer being adhered on a surface of the first circuit layer away from the base layer; defining at least one blind holes in the flexible resin coated copper, the blind hole passing through the copper layer and the first insulating layer, a portion of the first circuit layer being exposed from the blind hole; and filling a plating structure in the blind hole, the copper layer being electrically connected to the first circuit layer by the plating structure filled in the blind hole, thereby forming a flexible printed circuit board; wherein the first insulating layer, the copper layer and the plating structure forming an electromagnetic shielding structure.
