Problems solved by technology

These loads may deform the case, thereby making the board mounting surface of the bottom of the case less flat than the printed circuit board.
That is, coplanarity between the bottom surface of the housing and the printed circuit board cannot be ensured
Therefore, the electrical connection reliability between the bottom surface (circuit board mounting surface) of the case and the printed circuit board is deteriorated

Abstract

The IC socket assembly includes the heat sink for abutting the upper surface of an IC package to dissipate heat generated thereby, and a fixing member for fixing the heat sink to the housing. The fixing member includes: a frame, mounted on a surface of the circuit board, on which the housing is mounted; a back plate, mounted on the opposite surface of the circuit board, having engaging arms, which are inserted through apertures of the circuit board and engage the frame; a pair of loading beams, fixed to the engaging arms; and a pair of levers, axially supported by the loading beams, for urging the heat sink toward the housing.

Description

technical field [0001] The present invention relates to an IC socket of the type that dissipates heat generated by an integrated circuit package with a heat sink. More particularly, the present invention relates to IC socket assemblies in which the heat sink is mounted by pressing onto the IC assembly in the IC socket. Background technique [0002] Known conventional IC socket assembly such as in Japanese unexamined patent application No.2001-24370 ( figure 1 and 2 ) published in . Such an IC socket assembly includes a heat sink mounted on top of an IC assembly mounted on a socket housing. The linear mounting / moving / pressing element is rotatably connected to the IC socket. The heat sink is pressed against and mounted to the IC package by the linear element. [0003] Another conventional IC socket assembly is known as disclosed in Japanese Unexamined Patent Application No. 2003-7942 (FIG. 3). The IC socket assembly includes a socket housing housing a plurality of electr...
