Abstract:
1. A substrate comprising: a plurality of circuits; a plurality of ground planes comprising a ground plane corresponding to each of the plurality of circuits, each of the plurality of ground planes being spaced apart and disconnected from others of the plurality of ground planes; an edge card male connector comprising a first and second plurality of contacts; a first layer comprising a first portion of each of the plurality of circuits, and a first portion of each of the plurality of ground planes, the first plurality of contacts being on the first layer and including contacts corresponding to the first portion of each of the plurality of circuits, for each of the plurality of circuits, the contacts of the first plurality of contacts corresponding to the circuit comprising at least one ground plane contact electrically connected to the first portion of the ground plane corresponding to the circuit and at least one circuit contact electrically connected to the first portion of the circuit; a second layer comprising a second portion of each of the plurality of circuits, and a second portion of each of the plurality of ground planes, the second plurality of contacts being on the second layer and including contacts corresponding to the second portion of each of the plurality of circuits, for each of the plurality of circuits, the contacts of the second plurality of contacts corresponding to the circuit comprising at least one ground plane contact electrically connected to the second portion of the ground plane corresponding to the circuit and at least one circuit contact electrically connected to the second portion of the circuit; a first intermediate layer positioned between the first and second layers, the first intermediate layer comprising a third portion of each of the plurality of ground planes; and a second intermediate layer positioned between the first intermediate layer and the second layer, the second intermediate layer comprising a fourth portion of each of the plurality of ground planes, for each of the plurality of ground planes, the first, second, third and fourth portions of the ground plane being electrically interconnected.
