Attaching device for mounting and fixing a semiconductor device and a heat sink provided on the semiconductor device on a board, a mount board having the board, the semiconductor device, and the heat sink, and an attaching method of the semiconductor device and the heat sink provided on the semiconductor device on the board
US 20040257771 A1
wherein the semiconductor device and the heat sink are fixed to the board by an attaching device,
the attaching device comprising:
a press mechanism that presses the heat sink to the semiconductor device when the rotation member is rotated.
2. The attaching device, as claimed in claim 1, wherein
3. The attaching method as claimed in claim 1 wherein when the rotation member is rotated, a contact part provided at the rotation member comes in contact with a contact member having a spring configuration and provided at the heat sink, so that the contact member is bent.
This application is a continuation of international application PCT/JP00/05224, filed on Aug. 3, 2000 and a division of U.S. Patent Application Ser. No. 10/356,744, filed on Feb. 3, 2003.
[0004]FIG. 1 is a exploded perspective view showing a structure of a mounted board on which a related art socket is mounted.
Second terminal receiving hole forming parts 2-2 c having larger diameters than the first terminal receiving hole forming parts 2-1 c are formed at a position corresponding to the first terminal receiving hole forming parts 2-1 c surrounding the opening part 2-1 b of the member 2-1 and facing each other. Each second terminal receiving hole forming part 2-2 c is connected to a contact hole forming part 3 a that is formed at the board 3 so as to make a through hole. A wide end part of a contact 500 is provided at the second terminal receiving hole forming part 2-2 c and the other end part of the contact 500 goes through the contact hole forming part 3 a.
A claw part 2 e is provided at one side part in the X2 direction of the member 2-2 of the socket 2. Furthermore, a claw part 2 f is provided at one side part in the X1 direction of the socket 2. In addition, claw parts 2 g and 2 h are provided at one side part in the Y1 direction of the member 2-1 so as to be off set to the Z1-Z2 direction and the X1-X2 direction. Furthermore, the lever 2 i is rotatably provided at an end part of one side part in then X1 direction of the member 2-1. A head end part of the lever 2 i has a step-like configuration.
The fan 6 is provided at the upper part of the heat sink 5. A large number of fins 5 a having long lengths in the Y1-Y2 direction stand at the heat sink 5. A groove forming part 5 b is formed so as to cross through the large number of fins 5 a in the X1-X2 direction. A metal fitting 5 c for fixing is provided at the groove forming part 5 b detachably or movably at least in the X1-X2 direction. The metal fitting 5 c is formed like a plate spring so as to bend in the Z2 direction in a convex configuration. Receiving parts 5 c-1 and 5 c-2 having rectangular configurations and opening parts are formed at respective end parts of the metal fitting 5 c.
The mount board 1 having the above mentioned structure is assembled by the following steps.
After that, the receiving parts 5 c-1 and 5 c-2 are bent in the Z2 direction so that the receiving part 5 c-1 is received at the claw part 2 f of the socket 2 and the receiving part 5 c-2 is received at the claw part 2 e of the socket 2. As a result of this, the heat sink 5 is fixed at the socket 2 with the semiconductor device 4. (a heat sink fixing process) At that time, the heat sink 5 is pressed and stands close to the semiconductor device 4 by a spring force generated by the deformation of the metal fitting 5 c.
Furthermore, the connector 7 a is connected to the electric power source connector 7 b. (a connector connecting process) FIG. 2 is a perspective view showing a state where the mounted board 1 shown in FIG. 1 is assembled.
