Abstract: An interposer assembly includes a dielectric plate having a plurality of contact passages extending through the plate with a contact in each passage. Each contact includes a pair of laterally spaced contact points at the top and bottom of the plate. Sandwiching of the interposer assembly between two substrates brings the contact points on each spring arm into engagement with a pad, elastically bends the contacts and forms redundant high pressure wiped electrical connections between the contact points and pads.

Abstract: An interposer assembly includes a dielectric plate having a plurality of contact passages extending through the plate with a contact in each passage. Each contact is formed from a length of cylindrical preplated metal wire having a small diameter. Interposer assemblies with contacts formed from small diameter wire contacts have reduced contact inductance and permit reduction of the thickness of the dielectric plate and of the spacing between adjacent contacts on the plate.
