Patent abstract
An upper side and a lower side of a coupling member are provided with spiral contacts including elastic deforming portions. The elastic deforming portions are made contact with connectors of an IC package. Thereby, contact pressure on the IC package can be reduced. Further, the coupling member is replaceably positioned with respect to a substrate. Accordingly, only the coupling member can be replaced as needed, and therefore, maintenance fee can be reduced.
