Abstract

Serpentine trace patterns are used to add length to traces for matching delays to groups of signals on separate transmission pathways on circuit boards. By providing reverse coupling by patterning the traces in concentric fashion, this invention enables closer spacing between adjacent trace segments of the serpentine pattern.
