Abstract:
A connecting assembly for connecting a microelectronic element having an array of bump leads, comprising:(a) a substrate having electrically conductive leads;(b) a resilient, sheetlike body having first and second major surfaces, said second major surface facing said substrate;(c) a support structure extending between said second major surface of said sheetlike body and said substrate, said support structure spacing said sheetlike body away from said substrate, said support structure having gaps and solid portions therein; and(d) an array of generally laminar contacts secured to said first major surface of said body in registration with the array of bump leads on the microelectronic element to be mounted, and in alignment with said gaps, each said contact surrounded by an associated portion of said sheetlike body supported at its periphery by said solid portions of said support structure, at least a portion of said sheetlike body surrounding each said contact in alignment with said gaps being at least partially uninterrupted, whereby said contacts are deflectable toward said substrate upon urging the bump leads on the microelectronic element against said contacts.
