Compliant interconnect apparatus with laminate interposer structure

摘要

Apparatus to electrically connect a first electrical contact to a second electrical contact includes opposed upper and lower elastomer layers formed on either side of an electrically insulating intermediate layer together forming a laminate interposer structure having a thickness. An electrically conducting elastic column to provide a localized conductive path is formed through the thickness of the laminate interposer structure. The upper and lower elastomer layers provide compliance between the upper and lower elastomer layers and the elastic column, and the intermediate layer provides reduced compliance between the intermediate layer and the elastic column relative to the compliance between the upper and lower elastomer layers and the elastic column.
