EMI NOISE REDUCTION PRINTED CIRCUIT BOARD, CAPABLE OF BLOCKING THE RADIATION NOISE BY INSERTING THE ELECTROMAGNETIC BAND GAP STRUCTURE INTO A SUBSTRATE

摘要

PURPOSE: An EMI noise reduction printed circuit board is provided to easily block the radiation noise radiated from an edge of a substrate by modifying the simple structure of the substrate.;CONSTITUTION: A ground layer and a power layer are prepared on the first area. A second area(200) having electromagnetic band gap structure is located on a side of the first area. The second area comprises the electromagnetic band gap structure in order to shield the EMI noise emitting through the side of the first area to outside.;COPYRIGHT KIPO 2011
