Technical Field
[0001] This application relates to the field of integrated circuit packaging technology, and particularly to a Clip copper clip frame avoidance structure. Background Art
[0002] CU-Clip packaging (copper clip packaging) is a high-performance semiconductor packaging technology that uses a copper clip structure to directly connect the electrodes of a chip to a packaging substrate or other electrodes. Specifically, the copper clip directly covers the surface of the chip, and the chip electrodes are connected to the external circuit through pressure and welding. This method can effectively reduce the resistance and thermal resistance, and improve the performance and reliability of the device.
[0003] In the production process of Clip copper clips, the avoidance structure is one of the key designs, and its purpose is to ensure that the copper clip and the separator paper can be smoothly separated during feeding, conveying, and positioning, and avoid material jamming. However, the existing avoidance structure designs often affect the production efficiency and cost due to problems such as piercing the separator paper or low material utilization rate.
[0004] Current common solutions include increasing the distance between the avoidance structure and the Clip body, and adopting a complex bending process to improve the structural stability. However, these methods often increase the material consumption and production cost, and may not effectively prevent the piercing problem, that is, the existing avoidance structure designs often have difficulty in maximizing the use of materials while ensuring that the separator paper is not pierced.

[0039] The following is a further detailed description of the present application.
[0040] Referring to Figure 1 And Figure 2 , in the related art, a plurality of avoidance structures 12 are provided on both side edges of the frame body 10, and the bending angle of the avoidance structure 12 is set to 60°. In actual implementation, setting a plurality of avoidance structures 12 on both side edges will not only increase material consumption and production costs, but also cannot effectively prevent the piercing problem in combination with the bending angle. To solve this problem, the present application proposes a new technical solution, as follows:
[0041] Referring to Figure 3 And Figure 4 , in an embodiment of the present application, a Clip copper clip frame avoidance structure is disclosed. The avoidance structure 12 is provided on the frame body 10 and adopts an arc-sinking structure.
[0042] Among them, the setting of the arc-sinking structure can not only effectively prevent the problem of piercing the spacer paper, but also maximize the utilization of materials at the same time.
[0043] Specifically, a plurality of sub-frames 11 are arranged side by side on both sides of the frame body 10, and the avoidance structure 12 is arranged between both sides of the frame body 10. In this way, compared with the prior art, materials can be maximally utilized to avoid adding positions on the frame body 10, that is, both sides, to place the bending structure.
[0044] Referring to Figure 5 , a cross-section is made of the first bending portion 111 and the second bending portion 112 of a sub-frame 11 in the frame body 10 to obtain cross-sectional views of the two parts, so as to obtain the bending height A corresponding to the first bending portion 111 and the bending height B of the second bending portion 112.
[0045] Among them, the bending height C of the arc-sinking of the avoidance structure 12 is set to be greater than the bending height A and the bending height B, so as to prevent structural extrusion deformation when the frame is wound up.
[0046] In this embodiment, a plurality of avoidance structures 12 are arranged on the frame body 10 and are parallel to the sub-frames 11 on both sides, so as to further improve the flexibility and applicability of avoidance, enabling effective component avoidance in different positions and directions.
[0047] In summary, an avoidance structure for a Clip copper clip frame disclosed in an embodiment of the present application, by adopting an arc-sinking structural design for the avoidance structure 12, can effectively prevent the problem of piercing the separator paper, and at the same time can maximize the utilization of materials; the avoidance structure 12 is arranged between the two sides of the frame body 10, which can maximize the utilization of materials to avoid adding positions on the frame of the frame body 10 to place the bending structure; the bending height of the avoidance structure 12 is set to be greater than the bending heights of the first bending part 111 and the second bending part 112 to precisely control the sinking height, so as to effectively prevent the structure from being extruded and deformed during winding.
[0048] See Figure 6 and Figure 7 In another embodiment of the present application, an avoidance structure for a Clip copper clip frame is disclosed. The avoidance structure 12 is arranged on the frame body 10 and adopts a bent and sunken structure.

[0050] It is worth mentioning that when the avoidance structure 12 is arranged at the vacant position of the sub-frame 11, the space inside the frame can be utilized more fully to improve the space utilization rate.
[0051] See Figure 8 For a cross-section of the first bending part 111 and the second bending part 112 of a sub-frame 11 in the frame body 10, sectional views of the two parts are obtained, so as to obtain the bending height A corresponding to the first bending part 111 and the bending height B of the second bending part 112.
[0052] Among them, the bending height C of the bent and sunken structure of the avoidance structure 12 is set to be greater than the bending height A and the bending height B, so as to prevent structural extrusion deformation when the frame is wound up.
[0053] In this embodiment, the avoidance structure 12 is provided on each sub-frame 11, so that the frame body 10 has the avoidance ability at each key part, further preventing the puncture of the separator paper, ensuring the integrity of the separator paper, and also significantly improving the stability and reliability of the overall structure. Even in the case where multiple components need to be avoided simultaneously, this structure can also provide good support.
[0054] It should be noted here that the same reference numerals are used for the same names in the above different embodiments, and their corresponding structures may be different.
[0055] In summary, a Clip copper clip frame avoidance structure disclosed in another embodiment of the present application can ensure the effective avoidance function of the avoidance structure 12 in a compact space by precisely controlling the bending angle to prevent the puncture of the separator paper, and at the same time can maximize the use of materials; the avoidance structure 12 is arranged at the vacant position of the sub-frame 11 to make full use of the internal space of the frame to improve the space utilization rate; the bending height of the bending and sinking structure is set to be greater than the bending heights of the first bending part 111 and the second bending part 112 to precisely control the sinking height, so as to effectively prevent the structure from being squeezed and deformed during winding.
