Abstract
Abstract An IC carrier has an IC body and a flexible wiring sheet superimposed on and contacted with the IC body. The carrier is loaded in a socket so that the wiring sheet may contact the socket. The socket comprises an elastic backup member for elastically pressing the superimposed portion of the wiring sheet so as to contact with the IC body. An operating device deflects the elastic backup member between the pressing position and a press-releasing position.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
166 words
A socket and IC carrier arrangement, comprising: an IC carrier having an IC body thereon, said IC body having a plurality of contact pieces thereon; a flexible wiring sheet superimposed on and contacted with said IC body, said flexible wiring sheet having leads thereon each having a first contact pad disposed on a superimposed portion of said flexible wiring sheet and a second contact pad disposed outside of said superimposed portion, and each of said leads contacting corresponding ones of said contact pieces of said IC body with said first contact pads; and a socket having said IC carrier therein, said socket comprising an elastic backup member for elastically pressing said superimposed portion of said wiring sheet into contact with said IC body in a pressing position and releasing pressure on said superimposed portion in a pressure-release position, an operator for deflecting said elastic backup member between said pressing position and said pressure-release position, and contact members for contacting respective ones of said second contact pads.
Claim 2
Dependent Claim
166 words
A socket and IC carrier arrangement, comprising: an IC carrier having an IC body thereon, said IC body having a plurality of contact pieces thereon; a flexible wiring sheet superimposed on and contacted with said IC body, said flexible wiring sheet having leads thereon each having a first contact pad disposed on a superimposed portion of said flexible wiring sheet and a second contact pad disposed outside of said superimposed portion, and each of said leads contacting corresponding ones of said contact pieces of said IC body with said first contact pads; and a socket having said IC carrier therein, said socket comprising an elastic backup member for elastically pressing said superimposed portion of said wiring sheet into contact with said IC body in a pressing position and releasing pressure on said superimposed portion in a pressure-release position, an operator for deflecting said elastic backup member between said pressing position and said pressure-release position, and contact members for contacting respective ones of said second contact pads.
Claim 3
Dependent Claim
129 words
