Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application is a continuation of international application No. PCT/CN20131074658, filed on Apr. 24, 2013 which claims priority to Chinese Patent Application Serial No, 201210153970.6 filed on May 17, 2012. 
     
    
     FIELD OF THE PRESENT INVENTION 
       [0002]    The present invention relates to micro-electronic packaging technology field, in particular to a kind of light-heat dual curing anisotropic conductive adhesive, anisotropic conductive film and their preparation methods. 
       BACKGROUND OF THE PRESENT INVENTION 
       [0003]    Anisotropic conductive film (ACF) has both unilateral conduction function and adhesion function. Currently, ACT is used for COG, TCP/COF, COB and FPC, in particular fur the electric connection between IC and ITO glass. It can connect a lot of minuscule wires which traditional connectors can not connect. 
         [0004]    Anisotropic conductive films are mainly applied to the products such as mobile handhelds, cell phones, digital cameras, computers, printers, keyboards, consumer electronics, TVs, GPS products, electronic dictionaries and so on. 
         [0005]    Traditional ACF consists of thermosetting resin, conducting particles, curing agent, plasticizer and so on. When producing ACF, firstly, we dissolve the above-mentioned components in toluene, butanone or other volatile solvents to make a lot of anisotropic conductive adhesive (ACA). Secondly, we coat the above-mentioned ACA on a plastic film, then blow plenty of hot air to dry the ACA. Then the above-mentioned solvent is removed, and the ACF is produced. Then we cut the ACF to make up anisotropic conductive adhesive film (ACF). During the course of production, plenty of polluted harmful waste gas will affect the health of the workers. 
         [0006]    The Chinese patent CN 1926675A and the Chinese patent CN1367219A both disclose a kind of light curing anisotropic conductive adhesive (ACA) or light curing anisotropic conductive film (ACF). Those patents use light curing technology when using some ACF to connect some electric components. The ACA only can be used to connect transparent electrode (for example ITO glass), but can not be used to connect non-transparent electrode (for example plasma panel ADD etc). The Chinese patent CN 101724361 discloses the method about using heat curing to promote light curing, but it does not apply light curing technology to produce ACF. The adhesion strength of light curing is not as good as heat curing. In recent years, in micro-electronic packaging technology field, the connecting technology between those electronic components such as PCB terminals and IC chips develops to be integrated, high-performance, multi-lead, and of narrow space length. The requirements about the performance of the ACF is more and more high. Light curing can not meet the requirements about high bond strength. 
       SUMMARY OF THE PRESENT INVENTION 
       [0007]    The technical problem to be solved by the present invention is to overcome serious environmental pollution due to using solvent during the course of producing ACF under the traditional technology. The present invention applies light-heat dual curing technology to produce ACF. Applying light curing method to producing ACF can avoid using solvent to protect the natural environment. Applying heat curing method for electric connection can get high adhesion strength between the electric components.

         [0099]    When the rotation shaft  18  rotates, the cup sleeve bracket  2  will rotate together.

         [0107]    The second motor synchronous wheel  5  is fixed to the distal end of the rotation shaft  42 . 
         [0108]    The magnetic levitation bearing synchronous wheel  6  is sleeved on the suspended magnet  34 . 
         [0109]    The bevel gear  7  comprises a first gear  72  and two second gears  74 . 
         [0110]    The first gear  72  is sleeved on the suspended magnet  34  and is above the magnetic levitation bearing synchronous wheel  6 . 
         [0111]    The two second gears  74  are fixed to the two ends of the first gear  72 . The first gear  72  can transmit force to the two second gears  74  to make them rotate. 
         [0112]    One of the three synchronous wheel belts  8  is fixed between the second motor synchronous wheel  5  and the magnetic levitation bearing synchronous wheel  6 . 
         [0113]    The two bevel gear synchronous wheels  9  are respectively fixed to the two second gears  74 . 
         [0114]    The four bearings  10  are respectively fixed to the cup sleeve bracket  2 . Two bearings  10  of the above-mentioned four bearings  10  are connected to the two bevel gear synchronous wheels  9 . 
         [0115]    The two mixing cup sleeves  11  are respectively fixed to the upper ends of the other two bearing  10 . So the two mixing cup sleeves  11  can be rotatablely fixed to the cup sleeve bracket  2 . 
         [0116]    The two cup sleeve synchronous wheels  11  are respectively fixed to the lower ends of the other two bearings  10 . 
         [0117]    The other two synchronous wheel belts  8  are respectively fixed between the two bevel gear synchronous wheels  9  and the two cup sleeve synchronous wheels  12 . 
         [0118]    When the first motor  1  is turned on, the rotation shaft  18  will rotate to make the cup sleeve bracket  2  rotate synchronously. The two mixing cup sleeves  11  rotate together with the cup sleeve bracket  2 , and the rotation shaft  18  is the axis of rotation, so this kind of movement of the two mixing cup sleeves  11  is called “revolution”. 
         [0119]    When the second motor  4  is turned on, the rotation shaft  42  will rotate. The second motor synchronous wheel  5  rotates to make the magnetic levitation bearing synchronous wheel  6  rotate. by the transmission of the synchronous wheel belt  8 . Then, the suspended magnet  34  and the first gear  72  rotate synchronously. The first gear  72  pushes the two second gears  74  to rotate. When the second gears  74  rotates, the two bevel gear synchronous wheels  9  rotate synchronously to make the two cup sleeve synchronous wheels  12  rotate by the transmission of the two synchronous wheel belts  8 , then the two mixing cup sleeves  11  rotate. This kind of movement of the two mixing cup sleeves  11  is called “rotation”.
