摘要:
Disclosed is a printed circuit board having an embedded electronic component, which includes a first insulating layer, an electronic component disposed in an opening formed in a thickness direction of the first insulating layer and having a metal bump, a polymer layer formed on one side of the first insulating layer and on which the electronic component is seated so that the metal bump of the electronic component perforates the polymer layer, a second insulating layer formed on the other side of the first insulating layer so as to embed the electronic component, a first circuit layer formed on the second insulating layer, and a second circuit layer formed on the polymer layer so as to be directly electrically connected to the metal bump that perforates the polymer layer, and in which roughness is formed on the polymer layer so that the force of adhesion of the polymer layer to a plating layer is enhanced, thus ensuring reliability of the electrical connection of a circuit layer which is subsequently formed.

Provided are a substrate with built-in electronic component and a method for manufacturing the same. The method for manufacturing a substrate with built-in electronic component includes: forming conductive temporary bumps which penetrate and protrude through a prepreg sheet; mounting and attaching an electronic component on the protruding temporary bumps; forming an embedded substrate by laminating other prepreg sheet on the attached electronic component layer, laminating a metal sheet on a bottom of a laminate or on a bottom and top of the laminate, and pressing the prepreg sheets and the metal sheet; forming contact grooves by removing partial regions of the metal sheet and by removing the temporary bumps exposed by the removal of the metal sheet regions; and filling the contact grooves with a conductive metal and forming a circuit pattern.

Disclosed is an embedded printed circuit board, in which electronic devices having different thicknesses can be embedded together, thus achieving highly dense electronic devices, and when electronic devices having considerably different thicknesses are embedded, two electronic devices which are comparatively thinner can be embedded in a perpendicular direction, thus reducing an embedding area and suppressing warping of the printed circuit board, and an insulating member the thickness of which is variably adjusted is interposed between base substrates, so that spaces between the electronic devices are completely filled therewith, thus solving the problem of void defects, resulting in reliable printed circuit boards, and, when a base substrate includes a core made of metal, the printed circuit board can less warp. Also a method of manufacturing the embedded printed circuit board is provided.
