Abstract:
1. A printed circuit board having electronic components embedded therein, comprising: a metal core layer having a cavity formed thereon; an electronic component embedded in the cavity and having a plurality of terminals, a first ground terminal included in the plurality of terminals being connected to the metal core layer; a first internal insulating layer stacked on one side of the metal core layer; a second internal insulating layer stacked on the other side of the metal core layer; a first circuit pattern formed on an external surface of the first internal insulating layer; and a second circuit pattern formed on an external surface of the second internal insulating layer, wherein the electronic component includes a through silicon via and has the first ground terminal being connected to a second ground terminal by the through silicon via and the second ground terminal formed on the other side thereof, wherein the second ground terminal is connected to the metal core layer by conductive adhesive, and wherein the conductive adhesive is formed between a lower surface of the electronic component and the second internal insulating layer, a side of the conductive adhesive is connected to the metal core layer, and the conductive adhesive is electrically connected to the second ground terminal with the metal core layer.
