IC socket contact medium having uniform contact force

摘要

An IC socket is provided which realizes a uniform pressure of contact with an IC package over the entire length of a row of contacts and thereby enables an appropriate evaluation of characteristics of the IC package. The IC socket mounted on a printed circuit board includes: a socket base having a large number of contacts arranged in a row and brought into contact with leads of an IC package; a cover bearing on the contacts through an elastic body; and fixing portions for securing the cover to the socket base; wherein a contact surface between the elastic body and the contacts is curved in a longitudinal direction and the curved surface is so shaped as to generate a uniform contact force between the contacts and the leads of the IC package.
