[Technical Field] This utility model relates to the field of module bonding production technology, and in particular to a pressure head that can reduce the defect rate of module bonding. [Background Technology] In the existing module bonding production process, the COG pressure head is much larger than the IC, which easily causes uneven heating of the pressure head, resulting in the COG MURA phenomenon shown in the electrical test, with a high defect rate, which is not conducive to production.

Detailed Implementation Methods
[0009] It should be noted that in this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.
[0010] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0011] Please see Figure 1 and Figure 2 The present invention relates to a pressure head that can reduce the module bonding failure rate. The pressure head body 10 includes a pressure head body 10. A cuboid pressure block 20 is integrally formed on the pressure head body 10. The cuboid pressure block 20 includes a rectangular pressing surface 21. The rectangular pressing surface 21 is used for direct contact with the module for pressing. The length of the rectangular pressing surface 21 is 33mm and the width of the rectangular pressing surface 21 is 3mm.
[0012] The pressure head body 10 has a heating rod hole 12 on one side, and a heating rod is inserted into the heating rod hole 12. The other side of the pressure head body 10 has a heating rod fixing hole 13, which is perpendicular to the heating rod hole 12 and is connected to the heating rod hole 12. The heating rod fixing hole 13 is used to fix the heating rod with a screw.
[0013] This invention relates to a pressure head that reduces module bonding failure rates. By reducing the contact area between the rectangular pressing surface 21 and the IC, it reduces scrap caused by bonding defects, improves yield, and reduces material loss. This saves manufacturing companies money, generates profits, and facilitates production.
[0014] The height h of the cuboid pressing block 20 is 6mm, which can effectively avoid other structures of the equipment during pressing and avoid structural interference.
[0015] The pressure head body 10 is made of ceramic and has good thermal conductivity.
[0016] The pressure head body 10 is provided with an inclined surface 15, which is close to the heating rod hole 12, to reduce the heat conduction volume and concentrate the heat on the cuboid pressure block 20.
[0017] The pressure head body 10 is provided with a temperature sensing wire fixing hole 14, which is located between the cuboid pressure block 20 and the heating rod hole 12. A temperature sensor is provided in the temperature sensing wire fixing hole 14 to monitor the heating temperature.
[0018] The distance between the temperature sensing wire fixing hole 14 and the cuboid pressure block 20 is between 1mm and 2mm.
[0019] The distance between the temperature sensing wire fixing hole 14 and the heating rod hole 12 is between 2mm and 3mm.
[0020] The pressure head body 10 is provided with a plurality of mounting and fixing holes 11 for screws to be inserted to fix the pressure head body 10.
[0021] Compared with the prior art, the pressure head of this utility model, which can reduce the module bonding failure rate, reduces the contact area between the rectangular pressing surface 21 and the IC by reducing the scrap caused by poor bonding, improving the yield, reducing material loss, thereby saving money for the manufacturing enterprise, creating benefits, and facilitating production.
[0022] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any modifications, equivalent substitutions and improvements made within the concept of the present utility model should be included within the patent protection scope of the present utility model.
