Abstract
Abstract An interconnect system for printed circuit boards. The interconnect system includes signal wafers that carry high speed signals between printed circuit boards. The interconnect system also includes power modules assembled from wafers. The power modules are compact, easy to manufacture and easily integrate with the signal contact wafers to provide a single connector.
