Example Embodiment

[0034] figure 1 Is an external perspective view of the IC socket 1 according to the present invention, and figure 2 Yes figure 1 A schematic lateral cross-sectional view of the IC socket 1 shown. The IC socket 1 is provided on a printed circuit board 2 and has a socket main body 3 made of an insulating material such as resin, and a frame 4 that can move upward and downward with respect to the socket main body 3 and is biased upward. In addition to the frame 4, the IC socket 1 also has constituent elements such as nesting, guides, and levers. Since these additional constituent elements are known, for the sake of simplification, their description is omitted, and they are also not mentioned in figure 2 Shown in. Such as figure 2 As shown, the socket body 3 has a plurality of contactors, namely a first contact pin 6a and a second contact pin 6b, which are used to place the BGA device 5 (measured and arranged on the upper half) under the BGA device 5. The raised area is electrica

Abstract

It is an object of the present invention to provide an IC socket that has a configuration to promote heat dissipation from an IC device in a simple configuration, and prevent overheating of the IC device under test. Contact pins 6c, similar to the contact pins 6a and 6b, are disposed in regions not corresponding to the signal balls 51 and the thermal balls 52 of the BGA device 5. Further, the contact pins 6c and the second contact pins 6b that are contacted to the thermal balls 52 are thermally connected to each other via a heat spreader.
