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.

Abstract: An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and metal contacts in the passages. The contacts have resilient upper and lower contact arms that deflect into upper and lower recesses of the plate when sandwiched between contact pads of overlying and underlying circuit members. The recesses are sized to accommodate solder connections between contact arms and contact pads.

Abstract: A connector utilized to electrically connect together conductive pads disposed on different substrates includes a flexible substrate having a plurality of conductive through-holes therein. A conductive line formed in the flexible substrate extends between at least two of the conductive through-holes. A plurality of contacts is mounted in the conductive through-holes of the flexible substrate.
