ABSTRACT:
FIELD OF INVENTION
The invention relates to a fixture for mounting a CPU into a portable-type computer system.
BACKGROUND OF INVENTION
Portable-type computer has gained popularity recently due to the portability, light weight and endurance of rechargable battery power. Nowadays, most portable-type computer can operate continuously for more than 8 hours with the fully-charged battery initially.
It is obvious that to install each and every required components into a limited space provided by a portable-type computer system, the assembly process of the portable-type computer system is far more difficult than that of a desktop-type computer system.
FIG. 1
shows how a CPU
70
is mounted to a predetermined socket region
74
of the motherboard of a portable-type computer system. The CPU
70
for portable-type computer system is generally in form of rectangular slice chip with a multiple of positioning holes
11
. The corresponding mounting region of motherboard includes a multiple of positioning holes
14
to be aligned with the positioning holes
11
of CPU
70
during mounting process. The area
12
shown is the heat dissipation area of CPU
70
. The input and output pins (not shown) are provided on the bottom surface of CPU
70
and respectively contact with gold fingers
72
on the motherboard when the mounting procedure is complete.
Due to only limited space is available during mounting of CPU, the input or output pins of CPU or some components near the socket region
74
may suffer damage if the mounting operation is made by an in-experience operator. In addition, transistors fabricated within the slice form CPU may also suffer damage, which can not be detected by naked eyes, if the applied force is not adequate either in direction or in magnitude.
In order to prevent the possible damage recited above, the following requirement are to be met. The CPU
70
must be positioned at the accurate predetermined location of motherboard. Secondly, the actual location of force applied on the CPU
70
and the magnitude of the force must be accurate.
One prior art technology regarding the invention is disclosed in Taiwan Patent Application 84204505 which was filed on Apr. 10, 1995 and issued as publication no. 255584 on Aug. 21, 1995.
SUMMARY OF INVENTION
To achieve the above requirements, the invention provides a fixture for mounting the CPU to the specified socket region of the motherboard. The fixture provided enables an in-experience operator to mount the CPU without making damage to the CPU and nearby components on the motherboard.
A fixture for mounting a CPU into a portable-type computer system having a motherboard with a mounting location is provided. The fixture includes a first device, a second device and a third device. The first device is responsive to a force and re-directs the force to a predetermined force-taking location of the CPU. The second device supports the first device and includes a through-hole. The third device is connected to the second means and positions the CPU onto the mounting location such that a predetermined alignment relationship between the CPU and the mounting location is maintained.
