Description

Technical Field

[0001] The invention belongs to the field of testing technology, and in particular relates to a chip fixing device. Background Art

[0002] In X-ray inspection, it is necessary to inspect the three axes X, Y, and Z. Since integrated circuit chips are generally flat, it is relatively simple to inspect the direction of one axis, but it is more troublesome to inspect the directions of the other two axes because the chip cannot be directly erected; and there cannot be auxiliary metal objects in the X-ray inspection, otherwise it will affect the inspection results. Therefore, in order to erect the core ray inspection piece, it is necessary to fix the chip to a non-metallic device, and by adjusting the posture of the non-metallic device, the inspection of the three axes X, Y, and Z can be achieved.

[0003] In the related art, when testing a chip, it is often necessary to stand the chip upright for testing. To achieve the uprighting of the chip under test, a relatively simple solution is to glue the chip to a ruler. This solution requires first gluing the chip to a ruler. After the X-ray experiment is completed, the chip needs to be removed and the glue remaining on the surface needs to be wiped off. This method is cumbersome and is likely to damage the chip. Summary of the invention

[0006] The lower shell has a groove, and the chip to be tested is arranged in the groove. The upper shell is connected with an elastic body, and the lower end of the elastic body faces the chip to be tested during the pressing process.

[0007] Furthermore, the elastic body and the upper shell are integrally formed.

[0008] Furthermore, the upper shell and the lower shell are both cube-shaped.

[0009] Furthermore, the upper shell, the lower shell, the elastomer and the buckle are all made of plastic.

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] A specific chip fixing device provided in an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0023] like Figure 1As shown, the chip fixing device provided in the embodiment of the present application comprises: an upper shell 1 and a lower shell 2, wherein the upper shell 1 is snap-connected with the lower shell 2;

[0024] like Figure 2 As shown, the lower shell 2 has a groove 21, and the chip to be tested 3 is arranged in the groove 21. The upper shell 1 is connected to an elastic body 11, and the lower end of the elastic body 11 faces the chip to be tested 3 during the pressing process.

[0025] The working principle of the chip fixing device is as follows: the chip fixing device provided in the present application comprises an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 are connected by a snap-fit ​​connection. A groove 21 is arranged in the lower shell 2. When testing the chip, the chip 3 to be tested is placed in the groove 21. When the upper shell 1 covers the lower shell 2, the lower end of the elastomer 11 connected to the upper shell 1 can press the chip 3 to be tested, so that the chip 3 to be tested is fixed.

[0026] Preferably, the elastic body 11 and the upper shell 1 are integrally formed.

[0027] Preferably, the upper shell 1 and the lower shell 2 are both cube-shaped.

[0028] Preferably, the upper shell 1, the lower shell 2, the elastic body 11 and the buckle are all made of plastic.

[0029] Preferably, the elastic body 11 is made of PCA or ABS material.

[0030] Preferably, the elastic body 11 includes a plurality of folded layers, and the elasticity range of the folded layers is 0.6 mm-1 mm. Figure 3 The folded layers are shown when they are tightly together. Figure 4 The picture shows the folded layer popping open due to elastic force.

[0031] Preferably, the thickness of the folded layer is 0.8 mm.

[0032] In some embodiments, the upper shell 1 is printed by a 3D printer.

[0033] Through experiments, it is found that under the above structure, the elasticity of the structure is moderate and can meet the fixing requirements. Because the light source of the X-ray shooting device is in a fixed direction, this structure is designed to be close to the shape of a cube, which can be easily rotated to achieve X-ray shooting in each axis. At the same time, because metal parts, that is, metal springs to cover the chip, cannot be used, this application adopts this design, which can adapt to the fixing requirements of most flat package type chips.

[0034] It is understandable that the connection between the upper shell 1 and the lower shell 2 can also be fixed by a fixing clamp, for example, through holes are provided in the upper shell 1 and the lower shell 2, and the fixing clamp fixes the upper shell 1 and the lower shell 2 through the through holes.

[0035] In the present application, the upper shell 1 is printed with a fold line structure through 3D printing technology. By controlling the thickness of the fold line structure, the stiffness and elasticity of the structure can be adjusted. After testing, the elasticity of the structure is moderate under the 0.8mm structure, and a relatively suitable elasticity can be achieved between 0.6mm and 1mm.

[0036] It can be understood that after the upper shell 1 and the lower shell 2 are fixed together, the elastic body 11 presses the chip under test tightly. Because the upper shell 1 and the lower shell 2 are both cubes, the chip fixing device can be erected at this time, so that the chip under test is also erected. In this way, the use of X-ray equipment for shooting can well realize the detection of the X, Y, and Z axes of the chip under test.

[0037] In summary, the present invention provides a chip fixing device, including an upper shell and a lower shell, the upper shell is snap-connected to the lower shell; the lower shell has a groove, the chip to be tested is arranged in the groove, the upper shell is connected to an elastomer, and the lower end of the elastomer is facing the chip to be tested during the pressing process; the present invention can be easily rotated, can adapt to the fixing requirements of most flat package type chips, and realize X-ray shooting in each axis.
