Abstract: Enhanced microfabricated spring contact structures and associated methods, e.g. such as for electrical contactors and interposers, comprise improvements to spring structures that extend from the substrate surface, and/or improvements to structures on or within the support substrate. Improved spring structures and processes comprise embodiments having selectively formed and etched, coated and/or plated regions, which are optionally further processed through planarization and/or annealment. Enhanced solder connections and associated processes provide a gap between substrates for componentry, and or improved manufacturing techniques using distributed spacers. Enhanced probe card assembly structures and processes provide improved planarization adjustment and thermal stability.

Abstract: An improved interconnection system is described, such as for electrical contactors and connectors, electronic device or module package assemblies, socket assemblies, and/or probe card assembly systems. An exemplary connector comprises a first connector structure comprising a contactor substrate having a contact surface and a bonding surface, and one or more electrically conductive micro-fabricated spring contacts extending from the probe surface, a second connector structure comprising at least one substrate and having a set of at least one electrically conductive contact pad located on a connector surface and corresponding to the set of spring contacts, and means for movably positioning and aligning the first connector structure and the second connector structure between at least a first position and a second position, such that in at least one position, at least one electrically conductive micro-fabricated spring contact is electrically connected to at least one electrically conductive contact pad.
