Abstract: An interposer plate assembly having an insulating plate and metal contacts in the plate with contact points above and below the plate and a central portion in the plate. Two cantilever arms extend from the central portion to each contact point. The central portion may be formed to have a large area to form an impedance shield for reducing impedance between adjacent signal contacts. Plastic bodies may be overmolded on separate contacts or on contact pairs and may have sliding fits in passages of the interposer plate. Contacts may be arranged as differential pairs with ground contacts located between the differential pairs.

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.

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.
