BACKGROUND  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a mount, and in particular to a mount suitable for use with different kinds of microprocessors during motherboard testing.  
         [0003]     2. Description of the Related Art  
         [0004]     As computers become cheaper, the demand for computer becomes larger. Thus, how to make computers cheaper but qualified is an important question for each manufacturer.  
         [0005]     Presently, each element in a computer needs to be tested during assembly. In motherboard testing, a motherboard is disposed on an electric jig, and a microprocessor, interface cards and other peripherals are then installed thereon.  FIG. 1  shows conventional microprocessor assembly steps for motherboard testing. A microprocessor  13  is first manually installed in a protecting port  14  of an untested motherboard  15  and then a clip  141  of the protecting port  14  is pressed down to fix the microprocessor  14 . A heat dissipation module with a heat sink  12  and fan  11  is then mounted on the microprocessor  13  before testing.  
         [0006]     In order to protect the microprocessor  13 , a large dissipation module is usually used in conventional testing, which may collide with interface cards or other elements, such as capacitors, mounted nearby on the motherboard  15 . A heat sink  12  larger than the microprocessor  13  and the protecting port  14  must be installed separately to provide adequate access during repeated manual attachment and detachment. If the microprocessor  13  is mounted under the heat sink  12  and installed in the protecting port  14  at the same time, pins of the microprocessor  13  may easily be bent or damaged, increasing fabrication costs. Allowable testing time in a production line is limited, such that separate assembly steps increase installation time and complexity thereof.

     DETAILED DESCRIPTION  
       [0021]      FIG. 2  is an exploded view of a mount for motherboard testing in a first embodiment of the invention. In  FIG. 2 , a mount  20  of the invention comprises a heat sink  23  with an extending portion  24  and a protecting port  25  removably disposed thereon.  
         [0022]     The heat sink  23  in this preferred embodiment is substantially cylindrical. The upper part of the heat sink  23  comprises a central hollow  232  and a plurality of radially arranged fins  231 . The central hollow  232  houses for a fan  22  mounted on a cover  21  fastened to the heat sink  23  by the screw  212  passing through the hole  211  thereof, forming a dissipation module. The cover  21  has a central hole covered by a metal mesh  213  acting as both a dissipation passage and safety guard for the fan.  
         [0023]     The heat sink  23  of the mount  20  comprises an extending portion  24  corresponding to the central hollow  232 . The extending portion  24  comprises a first part  241  and a removable second part  242 . The fins  231  and the first part  241  of the extending portion  24  are integrated. The first part  241  is cylindrical, but the removable second part  242  is rectangular to match the profile of a conventional microprocessor  1 . The second part  242  of the extending portion  24  is removably fastened to the first part  241  by screws  244  passing through the holes  243  thereof. The heat sink  23  and the removable second part  242  are made of aluminum or copper formed by cutting or extrusion.  
         [0024]     In  FIG. 2 , the mount  20  further comprises a protecting port  25  and a frame  26 . The protecting port  25  comprises a plurality of electrically connected extension pins  252  and holes  251  matching the pins  2  of the microprocessor  1 . The microprocessor  1  is inserted into the protecting port  25  and protects pins  2  from bending or damaging. Furthermore, the frame  26  is rectangular, matching the profile of the protecting port  25 , and fastened to the removable second part  242  by screws  262  passing through the holes  261  and  245 . After the frame  26  is fastened to the second part  242  of the extending portion  24 , the protecting port  25  housing the microprocessor  1  is pressed into the square hole of the frame  26  and engages therewith.  
         [0025]      FIG. 3  shows the mount  20  for motherboard testing of the embodiment of the invention. In  FIG. 3 , because of the extending portion  24  ( 241 ,  242 ) of the heat sink  23  in this preferred embodiment, access is not limited during microprocessor installation. The extension pins  252  of the protecting port  25  (shown in  FIG. 2 ) are easily aligned with the holes  7  of the protecting port  6  on the motherboard  5  to install the microprocessor  1  (shown in  FIG. 2 ) thereon. Moreover, height of the extending portion  24  ( 241 ,  242 ) of the heat sink  23  is adjustable by means of the separated second part  242 . Thus, the heat sink  23  will not interfere with the clip  8  of the protecting port  6  when installing the microprocessor.  
         [0026]     In  FIG. 4 , during installation of another microprocessor with equal or similar profile but different pin arrangement by the mount of the invention, a second protecting port  35  housing a second microprocessor  1 ′ can be easily applied. Similarly, the second protecting port  35  comprises a plurality of electrically connected second extension pins  352  and second holes  351  matching the second pins  2 ′ of the second microprocessor  1 ′.  
         [0027]     By way of the removable second part  342  of the extending portion, alternate second part  342 , frame  36  and protecting port  35  can be provided when required by a profile of the microprocessor  1 ′ being much larger than the first one in  FIG. 2 . Thus, the mount of the invention is compatible with different microprocessors and motherboards, providing increased flexibility.  
         [0028]     Moreover, the heat sink  23  of the invention can have other shapes, such as a rectangle. The fins  231  are not limited to radial arrangement, and can be parallel. The heat sink can be a conventional rectangular heat sink with an extending portion to avoid restriction of access caused by the heat sink.  
         [0029]     While the invention has been described by way of example and in terms of the preferred embodiment, it is acting as both understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
