Patent ID: 7972178

Claim:
A connector for attaching a high connection density micro device to a pair of spaced-apart substrates, comprising: a) an interposer having a substantially planar body and an outer set of contacts disposed in a first pattern adjacent a perimeter thereof, said outer set of contacts each having a lower portion projecting below a lower surface of said body and an upper portion having a first length projecting above an upper surface of said body and an inner set of contacts disposed in a second pattern inwardly of said outer set of contacts, each of said inner set of contacts having said lower portion projecting below said lower surface of said body and said upper portion having a second length projecting above said upper surface of said body, said second length being shorter than said first length; b) an upper socket having a first pattern of contacts disposed on a lower surface thereof and adapted to receive distal ends of said outer set of contacts therein; and c) a lower socket having a second pattern of contacts adapted to receive distal ends of said inner set of contacts at a lower surface thereof and a set of contacts adapted to removably receive a micro electronic device therein.
