[Prior Art] In general, when an integrated circuit chip (IC chip) is assembled on a printed circuit board, a plurality of solder balls are used as a connection medium. The solder balls are fixed on the metal contacts of the printed circuit board, and then the integrated circuit chips are then fixed to the upper ends of the solder balls. Thereby, the electrical signal transmission between the integrated circuit chip and the printed circuit board can be achieved by passing the solder balls. This type of assembly has some drawbacks such as the following: The thermal expansion coefficient of the integrated circuit wafer is comparable to the thermal expansion coefficient of the printed circuit board, and the thermal expansion coefficient of the integrated circuit wafer is smaller than that of the printed circuit board. Therefore, when the integrated circuit chip and the printed circuit board are subjected to thermal cycling, the difference in thermal deformation between the two is too large, which tends to cause excessive shear stress of the solder ball, causing the solder ball to be destroyed. In order to improve the above-mentioned deficiency, an underfill is filled between the integrated circuit chip and the printed circuit board, and the underfill covers the solder ball and contacts the bottom surface of the integrated circuit wafer and the top surface of the printed circuit board. The primer can reduce the shear stress of the solder ball due to thermal cycling and increase the service life of the solder ball. When filling the primer between the integrated circuit chip and the printed circuit board, it is conventional practice to use a needle. Please refer to the patent "Process for under filling a 201041470 . flip chip semiconductor device", which uses a syringe to dispense the primer to the side of the integrated circuit chip, and then the primer is due to the capillary effect ( The capillary effect is sucked into the lower side of the integrated circuit chip. However, this conventional practice has some drawbacks: since the syringe needs to be dispensed around the edge of the integrated circuit wafer, the dispensing operation takes a long time. In addition, the speed at which the primer flows from the side of the integrated circuit chip to the lower side of the integrated circuit chip is not fast enough, which is to be improved. On the contrary, the present inventors felt that the above-mentioned deletion could be improved, and therefore proposed a present invention which is rational in design and effective in improving the above-mentioned deficiency. SUMMARY OF THE INVENTION The main object of the present invention is to provide a primer printing method and apparatus which can apply a primer to a wafer # relatively quickly and allow the primer to flow under the wafer relatively quickly. The above object of the present invention, the present invention, the method of the invention provides a primer 〇' including the steps of: heating a package structure, the package wafer; a substrate and a plurality of solder balls 'the solder balls; q soil And the wafer is disposed on the solder balls; and the printed board has an opening; and the side of the top surface of the brush board is pushed to the other side, so that the silicone passes through the opening Located next to the wafer. Including a primer printing method, the package structure has a 卩 板 于 on the package structure, the package " 曰曰 片, a substrate and a plurality of solder balls, the solder balls are placed on the base 201041470 On the material, the wafer is disposed on the solder balls, the printing plate has an opening, and a primer is disposed on one side of the top surface of the printing plate; and the primer is used by the top surface of the printing plate by using a scraper - Pushing the side to the other side such that the primer passes over the wafer through the opening; and heating the package structure. A further embodiment of the present invention provides a primer printing apparatus comprising: a support base; a printing plate disposed above the support base, the printing plate having a plurality of openings; a doctor blade movably disposed Above the provincial printing plate; and a heating module disposed beside the support. Therefore, the present invention has the following beneficial effects: as long as the primer in the printing plate is pushed in one direction, the primer can be applied to the package structure and the wafer through the opening of the printing plate. In addition, the present invention uses a heating module to heat the package structure so that the package structure has a higher temperature, so that the capillary effect is more significant, allowing the primer to flow faster below the wafer. The detailed description and drawings of the present invention are to be understood as the invention [Embodiment] A first embodiment of the present invention proposes an underfill printing apparatus 'which can quickly coat a primer to the side of the wafer' and quickly allows the primer to flow under the wafer. Referring to the first and second figures, the primer printing device comprises a support base 10, a printing plate 20, a scraper 30 and a heating mold 201041470 group 40. The support base 10 can be placed in a package structure 5, the support base 10 having a vacuum suction zone u which can generate suction to attract the package structure 50. The package structure 50 includes a plurality of wafers 5 and a plurality of solder balls 52 and a substrate 53. The solder balls 52 are disposed on the top surface of the substrate 53, and the wafer 51 is disposed on the solder balls 52. Therefore, there is a gap between the wafer 51 and the substrate 53. The substrate 53 can be a circuit board or a crystal circle. The substrate 53 of the present embodiment is a circuit board. The printing plate 20 is disposed above the support base 1 . More specifically, the printing plate 20 is placed above the support base 1 by some fixing mechanism or structure (not shown). The type of printing plate 2 can be - steel plate or a mesh plate. The printing plate 20 has a plurality of openings 21 which extend vertically through the printing plate 20. The shape and size of the opening 21 corresponds to the shape and size of the wafer 51 of the package structure 50, and the opening 21 of the embodiment is an L shape and is located outside the two edges of the wafer 51. The shape and arrangement of the openings 21 are variously changed. Please refer to the third and fourth figures. In other embodiments, the partial openings 21 may be "inverted" or rectangular. Referring to the fifth figure, in other embodiments, the rectangular openings 21 are arranged in an L shape. Referring again to the first and second figures, the other elements of the primer printing apparatus of the first embodiment will be described. • The scraper 3 is movably disposed above the printing plate 2 (): in more detail, the scraper 3 is disposed on a transmission mechanism (not shown), and the driving mechanism drives the scraper 30 on the printing plate 2 〇 7 201041470 moves horizontally above. The transmission mechanism can be a screw, a pneumatic cylinder, etc., and is often used for a mechanism that produces horizontal motion. The heating module 40 is disposed on the left side of the support base 10. The top surface of the heating module 40 can be placed in the package structure. The heating module 40 itself generates thermal energy, which is applied to the package structure 5 to make the temperature field of the package structure 50. More in detail, the heating module 40 can generate a higher temperature hot gas, which is blown to the package structure 50 and transfers the heat energy to the package structure 5〇. Please refer to the sixth figure, and with reference to the first figure and the second figure, the first method of using the primer printing device of the first embodiment is as follows: firstly, the package structure 50 is placed on the heating module 4〇, and then started. The heating mode and the address 40 generate thermal energy, and the temperature of the package junction #50 starts to rise. This process is called “preheating and heating”. The temperature of the package structure 50 can be raised up to 3 〇〇 Celsius. After f, 50 is heated, the package structure 50 is moved to the support base 1 by a robotic mechanism (not shown). As soon as the vacuum suction zone u of the support base 10 is activated, it will be sealed. The printing plate 2 is then placed on the package structure 5: the opening 21 of the printing plate 20 is located outside the edge of the wafer 51, and a primer 60 is disposed on the right side of the top surface of the printing plate 2''. The knives 3G are moved from right to left over the printing plate 2Q. The primer 6G is pushed from the right side of the top surface of the printing plate 2G: = 60 is printed (4), and the primer 60 is coated through the opening 21. It is placed on the top surface of the substrate 53, and next to the wafer η. The primer 60 then flows into the lower side of the wafer 51 due to the capillary effect. On the bottom cymbal, it is known that as long as the squeegee is used to push the squeegee in one direction, the primer 60 can be applied to each wafer without conventionally, as for each Y曰#日山从+刀刎 母 母 母 日 51 51 51 51 51 51 51 51 Qiao' because the sealing structure 50 has been heated to _^ temperature, high two-fine effect, making the primer 6. Flowing into the wafer holder 51 relatively quickly, the primer printing apparatus of the first embodiment has the second/first use method in response to the following situation: since the package structure 50 is placed away from the heating module 4 After 1 支 of the branch, the temperature of the package structure 5 〇 will start to flow into the crystal. Therefore, the second = configuration will be applied after the primer 60 is applied to the wafer 51, and then the package junction is returned to the heating module 4 ,, so that the package structure $ 〇 is again referred to as the two-two process. After heating (4) "Μ". Thus, the sealing U 冓 50 can maintain high temperature, and the primer 6 〇 can flow under the wafer 51 more quickly. The primer printing device of the first embodiment has a third use mode. In the three modes of use, the package structure 5 omits the "pre-heating" operation, and is directly placed on the support base 1 to perform the primer coating operation (the primer 60 is applied on the side of the wafer 51), and then the package is packaged. The structure 50 is sent to the heating module 4 for heating, and the "post-heating" operation is performed. The high temperature causes the capillary effect to be intensified, and the primer 6 〇 quickly flows into the lower side of the wafer 51. The underprint printing apparatus of the example can substantially reduce the time during which the primer 60 is filled into the package structure 5 。. 9 201041470 Referring to the seventh figure, a second embodiment of the present invention proposes another offset printing apparatus, which is different from the first embodiment in that the primer printing apparatus of the second embodiment further includes a second heating. The module 70 is disposed, and the second heating module 7 is disposed beside the right side of the support. Referring to the eighth figure, the user of the primer printing of the second embodiment is as follows: First, the sealing structure 5 first enters the "preheating" operation of the heating module, and then is sent to the support base. The primer is applied to the primer 6 〇. Finally, the package structure 50 is sent to the "post-heating" process so that the sealing structure 50 is held at the rain temperature to allow the primer (9) to flow more rapidly below the wafer η. Modules 40 and 70, so apricot a 6 啕 rain add 50 in the first-plus number: the packaged book of the person-applied work 〇 in the brothers a heating plate group 7 〇 "post-heating" as a still, into the light The package structure of the coating operation can be pre-heated before the operation, saving the overall working time. The third embodiment of the present invention proposes that it can quickly apply the primer to the wafer, and the 'I brush method, The glue flows down to the bottom of the wafer. The primer printing == grounding shoulder - the primer of the embodiment or the second embodiment is printed as described above. That is to say, the primer printing method surface/setting, but not the second embodiment of the primer printing device of the second embodiment or the ninth drawing of May, and with the fifth figure - The bottom offset printing of the second embodiment of the embodiment and the execution method of the primer printing method of the embodiment are taken as an example, and the third comprises the following steps: 10 201041470 Step S101 - Using a heating module 4 to add 50, the package structure 50 has Most of the days ^ # 虿 数 several days of the film 51, a plurality of solder balls and a substrate 53, the solder balls 52 are located between the wafer 51 and the substrate magic.
