摘要： Provided is a printed circuit board, including: a core substrate including an internal circuit pattern on an upper surface or a lower surface; electronic devices which are formed to pass through the core substrate; an external insulating layer which covers the internal circuit pattern and the electronic devices; and an external circuit pattern which is formed on an upper surface of the external insulating layer, wherein a lower surface of the electronic devices protrudes from the lower surface of the core substrate to a lower part. Accordingly, in the embedded printed circuit board in which the electronic devices are embedded, when the electronic devices are mounted, because the insulating layer is formed regardless of a thickness of the electronic devices, the printed circuit board having a desired thickness regardless of the thickness of the electronic devices can be formed.

摘要： Disclosed are a printed circuit board and a method of manufacturing the same. The printed circuit board includes a core insulating layer including an isotropic resin, a first circuit pattern filled in a circuit pattern groove at an upper portion or a lower portion of the core insulating layer, a first insulating layer provided in a top surface thereof with a circuit pattern groove and covering the first circuit pattern, and a second circuit pattern to fill the circuit pattern groove of the first insulating layer. A material, such as polyimide, having an isotropic structure is employed for the core insulating layer, thereby preventing the substrate from being bent without glass fiber. Since the glass fiber is not included, the buried pattern is formed at the upper portion or the lower portion of the core insulating layer, so that the thin substrate is fabricated.
