[0002] With the rapid development of the semiconductor industry, core-less substrates are becoming more and more common. To control substrate warping during reflow, carriers are commonly used. However, the use of carriers brings a new problem: the carriers themselves can warp and deform over time due to various reasons such as collisions or equipment jams. Warped carriers can lead to various problems during operation, such as the inability to vacuum fix the substrates or warping of the reflow substrates. This often seriously affects product quality during substrate transfer and chip placement. Utility Model Content

[0029] Please refer to Figures 1 to 4 The present invention provides a carrier correction jig 100 comprising a base 10 and a pressure plate 20. The base 10 is used to place the carrier 200 to be corrected. The pressure plate 20 is pressed against the side of the carrier 200 to be corrected that is away from the base 10. The base 10, the carrier 200 to be corrected, and the pressure plate 20 are stacked in sequence to form a sandwich structure. Along the stacking direction, the base 10 and the pressure plate 20 can cooperate with each other to apply a compressive force to the carrier 200 to be corrected. The carrier correction jig 100 can correct warped and deformed carriers, thereby overcoming the warping problem of the carrier during operation, ensuring the normal use of the carrier, and thereby improving product quality.

[0030] It should be noted that the carrier correction jig 100 includes a base 10 and a pressure plate 20, so that the base 10 supports the carrier 200 to be corrected. In actual use, the carrier 200 to be corrected can be placed on the base 10 first, and then the pressure plate 20 can be pressed against the side of the carrier 200 to be corrected away from the base 10. In this way, the base 10, the carrier 200 to be corrected and the pressure plate 20 can be stacked in sequence to form a sandwich structure. At this time, along the stacking direction, the base 10 and the pressure plate 20 will cooperate to apply a pressing force to the carrier 200 to be corrected, so that the warped carrier 200 to be corrected can be restored to a horizontal state under the action of the pressing correction provided by the base 10 and the pressure plate 20. Generally, if the warping degree of the carrier 200 to be corrected is less than 2 mm, it can be considered that the carrier 200 to be corrected is in a horizontal state.

[0031] Regarding the actual structure, shape and size of the base 10 and the pressure plate 20, those skilled in the art should be able to make reasonable selections and designs based on actual conditions. It is only necessary to ensure that the orthographic projection of the carrier 200 to be corrected on the base 10 and the pressure plate 20 falls within the base 10 and the pressure plate 20 to ensure that the base 10 and the pressure plate 20 can play a pressing and correcting role at various positions of the carrier 200 to be corrected. No specific restrictions are imposed here. Generally, the carrier 200 to be corrected is a hollow rectangular structure. For example, Figures 1 to 4 As shown, the base 10 and the pressing plate 20 are both rectangular structures, and the sizes of the base 10 and the pressing plate 20 in the length direction and the width direction are larger than the size of the carrier 200 to be corrected.

[0032] In some embodiments, the weight of the base 10 and the pressure plate 20 can be used to apply a pressing force to the correction carrier 200. Although this method of applying a pressing force is simple, it may cause a problem that the correction effect is poor due to a small pressing force, or the base 10 and the pressure plate 20 may be too heavy to be carried. Therefore, in order to solve the above problems, as an implementation method, Figures 1 to 4 As shown, the carrier correction jig 100 also includes a fastener 30. The base 10 is provided with a mounting hole 11, and the pressure plate 20 is provided with a corresponding connecting hole 21. The fastener 30 is sequentially inserted into the connecting hole 21 and the mounting hole 11 to securely connect the base 10 and the pressure plate 20. For example, the inner wall surfaces of the mounting hole 11 and the connecting hole 21 are both provided with internal threads, and the outer wall surface of the fastener 30 is provided with external threads (the fastener 30 can directly use a bolt or screw in the prior art).

[0033] Please follow Figures 1 to 2 The order of sequence is understood. In actual use, after the carrier 200 to be corrected is placed on the base 10, the fastener 30 can be screwed manually or with the help of a tool so that the fastener 30 can be sequentially inserted into the connection hole 21 and the mounting hole 11. Moreover, through the mutual cooperation between the internal thread and the external thread, the fastener 30 can be threadedly connected to the pressure plate 20 and the base 10 respectively, thereby achieving a tight connection between the base 10 and the pressure plate 20. In the above process, as the fastener 30 is screwed in, the distance between the base 10 and the pressure plate 20 gradually decreases, and the pressing force exerted on the carrier 200 to be corrected by the cooperation between the base 10 and the pressure plate 20 gradually increases. When the correction is completed, the carrier 200 to be corrected can be removed by simply screwing the fastener 30 in the opposite direction.

[0034] For example, when the warpage of the carrier 200 to be corrected is small, the screwing depth of the fastener 30 can be controlled to be small. In this case, the distance between the base 10 and the pressure plate 20 is large, and the base 10 and the pressure plate 20 cooperate to apply a small pressing force on the carrier 200 to be corrected. Conversely, when the warpage of the carrier 200 to be corrected is large, the screwing depth of the fastener 30 can be controlled to be large. In this case, the distance between the base 10 and the pressure plate 20 is small, and the base 10 and the pressure plate 20 cooperate to apply a large pressing force on the carrier 200 to be corrected. Thus, by adding the fastener 30, the problem of applying the pressure to the carrier 200 to be corrected by the weight of the base 10 and the pressure plate 20 being small and having a poor correction effect, or the problem of the base 10 and the pressure plate 20 being heavy and difficult to carry, can be solved.

[0035] As an implementable method, Figure 1 As shown, the base 10 is provided with a receiving groove 12 for placing the vehicle 200 to be corrected, wherein the profile and size of the receiving groove 12 should match the profile and size of the vehicle 200 to be corrected, so as to position the vehicle 200 to be corrected through the receiving groove 12, and the mounting hole 11 is located on the outside of the receiving groove 12 to avoid damage to the vehicle 200 to be corrected when the fastener 30 is passed through the mounting hole 11.

[0036] As an implementable method, Figures 1 to 4 As shown, there are multiple mounting holes 11, which are evenly and spaced apart along opposite sides of the receiving groove 12. This allows the base 10 and the pressure plate 20 to be tightly connected at all locations along the outer edge of the receiving groove 12, thereby improving the uniformity of the pressing and correcting action exerted by the base 10 and the pressure plate 20 on the carrier 200 to be corrected, thereby ensuring a good correction effect.

[0037] As an implementable method, Figures 1 to 3 As shown, a protrusion 22 is provided on the side of the pressure plate 20 close to the base 10. The protrusion 22 is used to abut against the side of the carrier 200 to be corrected that is away from the receiving groove 12. As a result, even if the opposite sides of the pressure plate 20 with the connection holes 21 are already abutting against the opposite sides of the base 10 with the mounting holes 11, the protrusion 22 can still abut against the side of the carrier 200 to be corrected that is away from the receiving groove 12, so that the bottom of the receiving groove 12 and the surface of the protrusion 22 close to the base 10 cooperate to apply a pressing force to the carrier 200 to be corrected.

[0038] As an embodiment, the sum of the thickness of the protrusion 22 and the carrier 200 to be corrected matches the depth of the receiving groove 12. For example, Figure 3As shown, in this embodiment, the sum of the thicknesses of the protrusion 22 and the carrier 200 to be corrected may be greater than the depth of the receiving groove 12, or, in other embodiments, the sum of the thicknesses of the protrusion 22 and the carrier 200 to be corrected may be equal to the depth of the receiving groove 12, so as to ensure that the protrusion 22 can abut against the side of the carrier 200 to be corrected away from the receiving groove 12, and the phenomenon of the protrusion 22 failing to fit and contact the side of the carrier 200 to be corrected away from the receiving groove 12 will not occur.

[0039] In order to be able to judge whether the carrier 200 to be corrected needs to be corrected, as an implementation method, Figure 1 As shown, a mounting groove 23 is provided on the side of the pressure plate 20 away from the base 10, and a spirit level 24 is provided on the inner wall of the mounting groove 23 (the spirit level 24 can directly call the spirit level 24 in the prior art), and the carrier 200 to be corrected is placed between the bottom of the mounting groove 23 and the surface of the spirit level 24 close to the base 10.

[0040] During actual use, after the carrier 200 to be corrected is taken off the production line, or has been press-fitted and corrected by the carrier correction jig 100, the carrier 200 to be corrected can be placed between the bottom of the mounting groove 23 and the surface of the spirit level 24 close to the base 10, so as to judge by the spirit level 24 whether the warping of the carrier 200 to be corrected is within the qualified range (warping is less than 2 mm). If so, the operation can be resumed; if not, correction is required until the warping of the carrier 200 to be corrected is qualified.

[0041] As an implementable method, Figure 1 As shown, the edge of the pressure plate 20 is provided with an opening that communicates with the mounting groove 23, so that the carrier 200 to be corrected can be placed through the opening between the bottom of the mounting groove 23 and the surface of the level 24 near the base 10 without interfering with the level 24. The number of openings can be one or two, and those skilled in the art will be able to reasonably select according to actual circumstances.

[0042] As an implementable method, Figure 3As shown, the distance between the bottom of the mounting groove 23 and the surface of the level 24 near the base 10 matches the thickness of the carrier 200 to be corrected. For example, the distance between the bottom of the mounting groove 23 and the surface of the level 24 near the base 10 can be equal to the thickness of the carrier 200 to be corrected. Alternatively, the distance between the bottom of the mounting groove 23 and the surface of the level 24 near the base 10 can be slightly greater than the thickness of the carrier 200 to be corrected, ensuring that the carrier 200 to be corrected can be placed between the bottom of the mounting groove 23 and the surface of the level 24 near the base 10, thereby allowing the level 24 to detect the warpage of the carrier 200 to be corrected.

[0043] As an implementable method, Figures 1 to 4 As shown, there are multiple levels 24, which are evenly and spaced apart along opposite sides of the mounting slot 23 to detect the warpage at various locations of the carrier 200 to be corrected. For example, the levels 24 are detachably mounted on the inner wall of the mounting slot 23 via a snap-fit ​​structure.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
