Mounting interface for high density, high speed electrical connector

Abstract

A high speed, high density electrical connector. The connector includes conductive elements for carrying signals, such as differential signals, with compliant portions for making pressure mount connectors. The distal ends of the signal conductors may have, in one portion a radius of curvature that provides suitable pressure for mounting to a substrate and in other portions, a larger radius of curvature, which results in a desired impedance profile. The compliant portions may be configured to establish desired signal current flow and desired ground current in shields bounding the signal conductors, particularly adjacent to the compliant portions. The compliant portions may have structures that more evenly distribute rotation over the length of the compliant portion. Such techniques facilitate manufacture of closely spaced signal units that each carry a signal with high signal integrity and low crosstalk at
