An embedded circuit board includes a circuit board including a flexible base layer, a first conductive circuit layer, a second conductive circuit layer, two adhesive layers, and two copper plates. The first conductive circuit layer and the second conductive circuit layer are formed on corresponding opposite base layer surfaces of the base layer and electrically interconnected together. A photosensitive layer is located on one surface of the circuit board. A component is located within a mounting slot formed within the photosensitive layer. Each copper plate includes a flexible insulating film and forms a third conductive circuit layer. The flexible insulating film is adhered to a corresponding one of the circuit board or the photosensitive material layer by a corresponding one of the adhesive layers.

Embedded circuit board and method of making same

A method for manufacturing a flexible printed circuit board includes providing a first double-sided circuit substrate which comprises an electronic component. A multilayer circuit substrate having a mounting groove is also provided. The multilayer circuit substrate covers the first double-sided circuit substrate through an adhesive layer, causing the electronic component to be received in the mounting groove, thereby forming an intermediate product. At least one through hole is defined in the intermediate product, which when filled with conductive material electrically connects the multilayer circuit substrate to the first double-sided circuit substrate to form the flexible printed circuit board.
