Patent ID: 7207104

Claim:
A method of configuring a circuit layout for an electrical mounting board, the method comprising: providing a substrate having at least a first layer and a second layer separated by a substrate core layer; forming a pattern of signal traces on the first layer; forming a pattern of electronic component arrangements associated with the first layer; forming a plurality of conductive electrical ground traces on the first layer of the substrate, the traces of the first layer being formed in at least two groups arranged in a hybrid configuration so that a first group of substantially parallel electrical ground traces is arranged in a transverse relationship with a second group of substantially parallel electrical ground traces, the lengths and positions of the ground traces being arranged to accommodate the pattern of signal traces formed on the first layer and arranged to accommodate the pattern of electronic component arrangements associated with the first layer; forming a pattern of signal traces on the second layer; forming a pattern of electronic component arrangements associated with the second layer; forming a plurality of conductive electrical ground traces on the second layer of the substrate, the traces of the second layer being configured in at least two groups arranged in a hybrid configuration so that a third group of substantially parallel conductive electrical ground traces is arranged in a transverse relationship with a fourth group of substantially parallel conductive electrical ground traces, the lengths and positions of the ground traces being arranged to accommodate the pattern of signal traces formed on the second layer and arranged to accommodate the pattern of electronic component arrangements associated with the second layer; and forming a set of electrically conductive interconnects that pass through the substrate core to electrically connect electrical ground traces of the first layer with electrical ground traces of the second layer to form a multi-layer ground grid having a plurality of ringlets.
