Abstract:
1. A contact sheet, comprising: a first insulating base sheet having a plurality of through-holes formed therein in an array pattern; a second insulating base sheet having a plurality of through-holes formed therein in an array pattern that is laminated to said first insulating base sheet, wherein a first surface of said contact sheet is defined by one of said first and said second insulating base sheets and an opposed second surface of said contact sheet is defined by the other of said first and said second insulating base sheets; and a plurality of conductive contacts arranged between said first base sheet and said second base sheet, each said conductive contact comprising a first portion disposed and fixed between said first and said second base sheets in a position proximate an edge portion of a respective one of said through-holes such that each said first portion of each said conductive contact is substantially coplanar, an integral second portion extending a distance from said first portion in a length direction of said through-hole and protruding from said first surface of said contact sheet, and an integral third portion extending from said second portion and protruding from said second surface of said contact sheet such that each said third portion of each said conductive contact comprises an elastic cantilever contact portion; wherein a total area of said first portion of said conductive contact and a respective one of said through-holes is greater than a unit grid area formed by an arrangement of terminals of an electronic device; and wherein a total length of said second portion and said third portion of each said conductive contact substantially corresponds to a length of said through-holes; whereby the terminals of a plurality of electronic devices are connected via said conductive contacts of said contact sheet when said contact sheet is interposed therebetween.
