Abstract

A capacitor mounting method and resulting printed circuit board that increases the mounting density of both vias and decoupling capacitors is presented. Vias are shared between capacitors mounted on the top and bottom of the printed circuit board. This arrangement allows increased decoupling capacitor density and avoids the current doubling problem when shared vias are connected with capacitors installed on the same side of the board.
