Estimating the term…
Signal lines in the pin field of a printed circuit board layout are modified to reduce line impedance and improve signal integrity. The widths of signal lines are extended in the pin field to take full advantage of the available routing space between pads and adjacent signal lines. The signal line extension can be considered a subtractive approach in that the signal lines are extended to occupy the available muting space, with signal line extensions that would otherwise cause design rule violations being subtracted out. The edge of a signal line is extended to a keep-out region associated with a centerline that extends through a plurality of pads arranged in a line and located adjacent to the signal line. The edge of the signal line is also extended to keep-out regions associated with pads in the pin fields.
1-25. (canceled)
A printed circuit board comprising a signal line located adjacent to a plurality of pads, the plurality of pads arranged in a line from a first pad to a second pad, the signal line substantially filling an area bounded by a first centerline extending through the plurality of pads, a second centerline of the first pad, a second centerline of the second pad, and a first edge of the signal line that is a distal edge of the signal line relative to the first centerline, wherein the second centerline of the first pad and the second centerline of the second pad are orthogonal to the first centerline, the signal line substantially filling the area to an extent that it is spaced from the plurality of pads, a shape of a portion of an edge of the signal line in a vicinity of an individual pad substantially identical to a shape of a portion of the edge of the individual pad in a vicinity of the signal line.
