Abstract: A contact set and compressible interposer, methods for producing them and a compliant interconnect assembly for providing electrical connection of a first electronic device to a second electronic device. The compliant interconnect assembly comprises a contact set and a compressible interposer. The contact set includes an electrically insulating, flexible film with at least one conductive contact suspended therein to provide an electrically conductive path through the film. Formation of at least one de-coupling hole in the flexible film, close to a conductive contact, further contributes to independent movement of the conductive contact. A compressible interposer in the form of an electrically insulating elastomer matrix, surrounding electrically isolated conducting elastic columns, provides a localized conductive path through the thickness of the elastomer sheet.
