EMBEDDED MULTI-LAYER CIRCIUT BOARD AND NOISE SUPPRESSION METHOD

摘要

The invention relates to an embedded multi-layer circuit board and a noise suppression method. The embedded multi-layer circuit board comprises at least two ground layers, a power layer and a plurality of vias. The power layer is between two ground layers. Each via is electrically connected with the two ground layers and electrically isolated from the power layer. The power layer is divided to a plurality of periodical cells. Each cell comprises the same number of the vias.
