摘要: An EMI noise shield board, in which an EBG structure is inserted, includes a first board portion and a second board portion. The first board portion has an upper surface, on which an electronic part is disposed, and a circuit for transferring a signal and power to the electronic part. The second board portion is located on a lower surface of the first board portion. The electromagnetic bandgap structure is inserted into the second board portion, and has a band stop frequency property such that an EMI noise transferred from the first board portion is shielded from being radiated to the outside of the EMI noise shield board.

摘要: A printed circuit board and an electronic product are disclosed. In accordance with an embodiment of the present invention, the printed circuit board includes a first board, which has an electronic component mounted thereon, and a second board, which is positioned on an upper side of the first board and covers at least a portion of an upper surface of the first board and in which an EBG structure is inserted into the second board such that a noise radiating upwards from the first board is shielded. Thus, the printed circuit board can readily absorb various frequencies, be easily applied without any antenna effect and be cost-effective in manufacturing.
