Multipath interconnect with meandering contact cantilevers

Abstract

An interconnect assembly includes a number of interconnect stages combined in a carrier structure. Each interconnect stage includes at least two contact sets having an upwards pointing cantilever contact and a downwards pointing cantilever contact. The cantilever contacts are attached to the carrier structure and are arranged around openings in the carrier structure such that the downward pointing cantilevers may reach through the carrier structure. Each contact set defines an independent conductive path between a single pair of opposing chip and test apparatus contacts such that multiple conductive paths are available for each interconnect stage for increased transmission reliability and reduced resistance. The cantilever contacts have a meandering contour and are either combined in symmetrical pairs at their respective tips or are free pivoting. The meandering contour provides a maximum deflectable cantilever length within an available footprint defined by the pitch of the tested chip.
