Patent ID: 7083436

Claim:
An interposer, comprising: a sheet having an opening formed therethrough; an interconnect member extending through said opening and comprising a mixture of non-spherical and spherical conductive particles suspended in an elastomeric material and opposed first and second end surfaces; said conductive particles being suspended in substantially straight flow lines running from said first end surface to said second end surface; said non-spherical conductive particles including a plurality of elongated conductive particles; a portion of said sheet extending into said interconnect member, thereby securely positioning said interconnect member in said opening; and first and second portions of said elongated conductive particles extending through said first and second end surfaces, respectively; said interconnect member being formed using mold sections that include a pressure venting exit via that extends substantially parallel to a central axis of said interconnect member whereby said straight flow lines are produced: wherein said elongated conductive particles aligned parallel with said flow lines are substantially perpendicular to said first and second end surfaces, and wherein said interconnect member has a varying cross-section.
