New description: 【New technical field of the art】 This creation is related to the kind of point _, especially the porous spot for the patch. [Prior Art] The industry has a wide range of considerations, such as IC packaging, photovoltaic, liquid crystal display panel LCD panel sealant, LED factory LED package and LED turn, mobile phone case package, note-type computer fit, surface mount Use of technology (SMT) parts or printed circuit board assembly. #点赖程 is mainly the post-joining process of the joint. Its function is to protect the substrate, microcircuit, 1C' to prevent dust, moisture, light, etc. from entering the person to avoid damage to the product. The traditional wafer is a square design, so the dispensing head of the existing dispenser 1 is a single-point plastic needle 12 design. Under this architecture is sufficient for a square wafer to bond to the substrate. However, as the existing wafer shape is oriented toward a rectangular shape, the design of the single-pointed pin is not sufficient. For example, when using the structure of the knee to coat the adhesive material for coating, such as silver enamel, only the surface of the rectangular wafer is covered by the foot, resulting in a lot of voids between the wafer® and the substrate, so that the joint state is not In view of this, the author proposes a new dispensing head for the patch to effectively overcome the above problems in view of the above-mentioned shortcomings of the prior art. [New content] The main purpose of this creation is to provide a dispensing head for the patch. When the double-pointing needle is designed for use in a rectangular wafer, the coverage of the knee-shaped wafer on the surface of the rectangular wafer can be guaranteed to be 100%. Reduce the void of silver glue to achieve a firm bond between the rectangular wafer and the substrate. In order to achieve the above purpose, the present invention proposes a dispensing head for a patch, which mainly comprises a 3 M4 17 17 ZH and a dispensing assembly disposed at the bottom end of the body. The point win component includes a - spacer block and two __ spacers between the __ plastic needles. In order to make your reviewer have a better understanding of the structural features and the effects achieved by this reviewer, I would like to discuss the implementation of Wei Wei's detailed description of Wei He, as follows: [Implementation] μ and refer to Figure 2 Fig. 3 and Fig. 4 are respectively a perspective view of the dispensing head for the patch of the creation, a cross-sectional view of the line section of Fig. 2, and a bottom view of the dispensing assembly. As shown in the figure, the dispensing head 20 for the patch of the present invention mainly comprises a body 22 and a dispensing assembly 24 disposed under the body 22. Dispensing assembly 24 includes a spacer block 3, and two dispensing needles 32, % spaced apart by spacers 30. The spacer block 30 and the dispensing needle 32, % of the material may be tungsten steel, and the spacer block has a length Υ of 0.5 mm (mm), a width 〇 of 4 mils, and a thickness of (4) a needle dispensing needle. The length of 32, 34 is h5 mm (job), width... mil, thickness _ mil. Please refer to Figure 5, which uses a dispensing head for the substrate to make a substrate and a rectangular sheet. Here, the _ secret can be selected from the use of the silver plastic · · 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 因为 因为 因为 因为 因为 因为 因为 因为 因为 因为 因为 因为'When the knee needles 32, 34 are glued, when they are spotted on the substrate 38, two silver adhesive regions 40 are formed. Subsequently, when the rectangular wafer 42 is attached to the substrate 38, the silver adhesive region 4 形成 will form a good coverage on the rectangular wafer & the bottom surface, thereby reducing the void of the silver paste, thereby ensuring the stability of the rectangular wafer 42 and the substrate 38. Engage. In summary, this author proposes a new type of dispensing head for patch, which is characterized by a double 4 M412817 dispensing needle, which is used to ensure the fit of the rectangular wafer on the surface of the rectangular wafer. The coverage is 100%, and the void of silver glue is reduced, so that the rectangular wafer and the substrate can be firmly joined. The above descriptions are merely preferred embodiments of the present invention and are not intended to limit the implementation of the present invention. Therefore, any changes or modifications to the characteristics and spirits described in this application should be included in the scope of the patent application for this creation.
