Patent attributes
A short, high density interposer. The interposer has multiple contacts, with upwards and downwards-facing contact surfaces. Each of the contacts may be formed as a beam stamped from a sheet of metal. Two sheets of metal may be used in forming the interposer. A first sheet may be stamped with upwards facing contacts. A second sheet may be stamped with downwards facing contacts. Bases of the beams on the first sheet may be fused with bases of the beams on the second sheet, creating a conducting path through the interposer, with compliant contacts at each end. The joined contacts may be separated from the sheets from which they are stamped and held together with an insulative base of the interposer. Beams shaped to form contacts in the interposer may be closely spaced when stamped in a sheet of metal and may have a low height.
