Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit reflow soldering, in particular to an integrated circuit reflow soldering device. Background Art

[0002] The traditional power device packaging product (LFPAK Reflow) process uses solder paste welding technology. During the high-temperature welding process, the flux in the solder paste will volatilize and produce tar. These tars tend to accumulate at the top of the machine cavity. When a certain amount is reached, it may drip onto the heating block or the product, which will have an adverse effect on the product quality. In the power device packaging product (LFPAK) production line, the flux in the solder paste volatilizes during the high-temperature curing process, and the tar formed will condense on the upper layer of the vacuum cavity. After a long period of accumulation, it may form a water droplet shape. Once it drips onto the heating block or the product, it will cause product defects and further affect the overall quality of the product. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-3 The utility model provides an embodiment of an integrated circuit reflow soldering device, comprising an oil collecting hood 1 and a vacuum chamber 2. The oil collecting hood 1 is composed of two interconnected slope sections 11. The two slope sections 11 are not only symmetrically arranged, but also form a certain slope between each other to ensure that the tar can flow smoothly to both sides. One end of each slope section 11 extends vertically upward to form a vertical section 12. The top of the vertical section 12 extends horizontally to form a horizontal section 13. The horizontal section 13 is provided with screw mounting holes 14. These screw mounting holes 14 are used to fix the oil collecting hood 1 inside the vacuum chamber 2 by screws.

[0021] The oil collecting hood 1 is made of special stainless steel, which is resistant to high temperature and corrosion, and is easy to clean and maintain, thereby ensuring the stability and durability of the oil collecting hood 1 in a long-term high-temperature working environment.

[0022] A screw hole 21 is provided at each end of the vacuum chamber 2, which cooperates with the screw mounting hole 14 on the horizontal section 13 of the oil collecting cover 1, and the oil collecting cover 1 is firmly fixed inside the vacuum chamber 2 by high temperature resistant screws. The use of high temperature resistant screws ensures the stability of the connection during high temperature welding.

[0023] The oil collecting hood 1 and the vacuum chamber 2 are connected by screws, so that the oil collecting hood 1 can be easily disassembled and assembled, and is convenient for regular cleaning and maintenance, thereby maintaining efficient operation of the equipment and extending its service life.

[0024] Working principle:

[0025] When installing the oil collecting hood and vacuum chamber, the operator:

[0026] Place the oil collecting cover 1 at a suitable position inside the vacuum chamber 2;

[0027] Align the screw mounting holes 14 on the horizontal section 13 of the oil collecting cover 1 with the screw holes 21 at both ends of the vacuum chamber 2;

[0028] Select suitable high temperature resistant screws and fix the oil collecting cover 1 inside the vacuum chamber 2 through the screw mounting holes 14;

[0029] Check whether the oil collecting hood 1 is firmly fixed in the vacuum chamber 2 to ensure stability during welding.

[0030] The utility model is based on the design of the oil collecting hood 1. Its special shape and material can effectively collect and guide the tar generated during the solder paste welding process. When the flux in the solder paste evaporates and forms tar during the welding process, the tar will flow to both sides along the slope of the oil collecting hood 1 instead of randomly adhering to the surface of the vacuum chamber 2. This design avoids the tar from dripping directly onto the heating block or the product, thereby preventing product defects and quality degradation.

[0031] The two screw holes 21 inside the vacuum chamber 2 cooperate with the screw mounting holes 14 on the horizontal section 13 of the oil collecting hood 1 to ensure that the oil collecting hood 1 can be stably fixed inside the vacuum chamber 2. This structural design not only improves the stability of the equipment, but also simplifies the maintenance and cleaning process and improves production efficiency.

[0032] Through the above design, the integrated circuit reflow soldering device of the utility model can significantly improve the welding quality, reduce the defective rate in production, and at the same time simplify the maintenance and maintenance of the equipment, providing a strong guarantee for the high-quality production of integrated circuits.

[0033] When the oil collecting cover needs to be removed, the operator:

[0034] Turn off welding equipment and cool to a safe temperature;

[0035] Disassemble the connecting parts outside the vacuum chamber 2;

[0036] Loosen the high temperature resistant screws that secure the oil collecting cover 1.

[0037] Take out the oil collecting cover 1 and prepare to clean or replace it.

[0038] When the oil collection hood needs to be cleaned, the operator:

[0039] After removing the oil collecting cover 1, use a special cleaning agent to spray on the slope section 11, the vertical section 12 and the horizontal section 13.

[0040] Use a soft brush or non-metal scraper to gently scrub to remove tar residue.

[0041] Wipe the surface of the oil collecting cover 1 with a clean dust-free cloth to ensure that there is no residual cleaning agent.

[0042] Check whether the oil collecting cover 1 is damaged or deformed, and replace it if necessary.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
