Patent ID: 8432706

Claim:
A printed circuit board comprising: a first board having an electronic component mounted thereon; and a second board positioned on an upper side of the first board and covering at least a portion of an upper surface of the first board, an electromagnetic bandgap (EBG) structure being inserted into the second board such that a noise radiating upwards from the first board is shielded, wherein the second board comprises a first conductive body and a second conductive body disposed on a different surface, respectively; a third conductive body disposed on a surface that is different from that of the second conductive body; and a stitching via unit connecting the first conductive body to the third conductive body through the surface on which the second conductive body is disposed, the stitching via being electrically separated from the second conductive body, and wherein the electronic component is mounted on a surface of the first board, and the second board is stacked on the upper surface of the first board while a portion corresponding to the position of the electronic component is opened.
