Abstract

In printed circuit boards having dense printed connections, cross talk noise immunity is significantly improved by preferentially routing adjacent to one another serially connected conductors of the same net rather than conductors of different nets. By such routing inter-net cross talk is reduced while the resultant intra-net cross talk is maintained at tolerable levels.
