ELECTROMAGNETIC BAND-GAP STRUCTURE AND A CIRCUIT BOARD, WHICH INCLUDES THE DESIGN FLEXIBILITY OF THE CIRCUIT BOARD

摘要

PURPOSE: An electromagnetic band-gap structure and a circuit board are provided to apply for an electrical appliance including a system in package or a network board by overcoming a conductive noise problem.;CONSTITUTION: A plurality of first conductive plates(430-1) is located on the surface a first plane and is arranged to a first direction. A plurality of second conductive plates(430-2) is located on a second plane and is arranged to the first direction. A first stitching via(441) electrically connects neighboring conductive regions on the first plane to the opposite direction from the first direction. A second stitching via(442) electrically connects neighboring conductive regions on the second to the opposite direction.;COPYRIGHT KIPO 2010
