Abstract:
1. A method for manufacturing a circuit board comprising the following steps of: providing a core layer, wherein the core layer includes a first dielectric layer, and first and second metallic layers, the first dielectric layer has upper and lower surfaces, and the first and second metallic layers are located on the upper and lower surfaces of the first dielectric layer respectively; forming a first through hole in the core layer; disposing the core layer on a supporting plate, and disposing an embedded component in the first through hole, wherein the second metallic layer contacts the supporting plate, and the embedded component has at least one electrode contacting the supporting plate; mounting the embedded component in the first through hole by an encapsulating process; removing the supporting plate; removing the first and second metallic layers and decreasing the thickness of the electrode of the embedded component by a thickness decreasing process; forming third and fourth metallic layers on the upper and lower surfaces of the first dielectric layer respectively, wherein the fourth metallic layer is electrically connected to the electrode of the embedded component; and patterning the third and fourth metallic layers so as to respectively form first and second patterned circuit layers.
