Those skilled in the art can fully understand the present application without the description of these details.

[0015] See also Figure 1 to Figure 3 A paste-coating jig for a single-tube IGBT assembly includes a bracket 1 and a paste-coating steel mesh 5. The bracket 1 is provided with a receiving groove 2, a plurality of positioning grooves 3 and a plurality of limiting frames 4. The plurality of limiting frames 4 are arranged around the receiving groove 2. A placement space for placing the paste-coating steel mesh 5 is formed between the plurality of limiting frames 4 and the bracket 1. The paste-coating steel mesh 5 is provided with a plurality of hollow grids 501. A positioning groove 3 is arranged directly below each hollow grid 501. The limiting frame 4 is in a right angle shape, and the top of the limiting frame 4 is turned outward to form a flange 401. The flange provided makes it easier to place the paste-coating steel mesh in the placement space.

[0016] The limiting frame 4 is in a rectangular parallelepiped shape, which is easier to process and has low equipment cost.

[0017] The receiving groove 2 is in a rectangular parallelepiped shape, which is easier to process and has low equipment cost.

[0018] The positioning groove 3 is in a rectangular parallelepiped shape, which is easier to process and has low equipment cost.

[0019] The accommodating groove 2 is arranged above the positioning groove 3 .

[0020] When the utility model is used, each IGBT component 6 is respectively clamped in the positioning groove 3, the paste-coated steel mesh 5 is placed in the placement space, and the paste is applied to the position of the hollow grid 501. The paste passes through the hollow grid and is applied to the IGBT component 6. After the paste is applied, all IGBT components are highly consistent and the paste is applied evenly. The use of the utility model greatly improves the paste application quality and speed, reduces the product defect rate, and ensures the product temperature rise.
