Latest Patents

Yamaguchi's latest patents include an IC socket and a spring means of IC socket. These inventions provide an IC socket with good durability, allowing for accurate electrical tests on the IC over extended periods. The design features an elastically deformable metal plate fixed within a spring accommodating portion of a support board. This metal plate includes a plurality of spiral cantilevers that correspond to the bumps of the IC. The flat tip of the spiral cantilever supports an insulative resin film. When the IC is pressed by an IC pressing part, the bump of the IC flexibly deforms the spring part via the insulative resin film. This results in a contact pressure due to the elastic force of the spring part occurring in the contact area between the bump and the contact pad.
