Abstract
Abstract An electrical socket (10) for interconnecting circuits on an integrated circuit chip to circuits on a substrate is disclosed. The socket (10) includes a base section (12), an upper section (16) and a metallized plastic membrane (14) having circuit traces (72) thereon. Contact pins (52) in the upper section (16) electrically connect circuits on the chip to inner ends (82) of the traces (72) and outer ends (84) of the traces (72) engage circuits on a substrate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
An electrical socket for interconnecting integrated circuit chip circuits to circuits on a substrate, comprising: a base section; an upper section having a contact pin retaining portion, conductive contact pins in said retaining portion with first and second ends protruding from opposite surfaces and a frame overlying said retaining portion and having an opening therethrough for receiving an integrated circuit chip with circuits on said chip engaging first ends of respective said contact pins; and a membrane comprising a dielectric base layer with conductive circuit traces on one surface thereof, said membrane having an inner portion positioned between said base section and said upper section with inner ends of said circuit traces engaging second ends of said contact pins and an outer portion extending outwardly from said socket with outer ends of said circuit traces engaging circuits on a substrate.
Claim 2
Dependent Claim
140 words
