Description

Technical Field

[0001] The utility model belongs to the technical field of SSD testing, and in particular relates to a testing auxiliary device for an SSD board card. Background Art

[0002] Nowadays, the signal integrity verification of the NAND Flash chip on the SSD board needs to be performed while the business is running. When the SSD is running, it is under a great pressure, which greatly increases the working temperature of the SSD. In addition, most of the test points are on the bottom of the SSD, so the main controller chip side cannot be effectively cooled, which can easily cause the hard disk to alarm and hang up due to high temperature during the test. If the SSD is not effectively cooled in time, the SSD disk speed may drop during the test, the business may be suspended, and the SSD may even hang directly. Therefore, it is very important to be able to effectively cool the SSD during the test.

[0003] In addition, most enterprise-level SSD interfaces are U.2 interfaces. When testing, an adapter cable is usually required to connect to the PC, and then a welding front end that matches the high-speed active differential probe is welded at the test point. The welding front end is welded with silver wire, and the silver wire is welded to the test point. When testing NAND Flash chips, at least 4 signals are required, and 4 high-speed active probes are required at the same time. Torsion is very likely to occur between the probe and the adapter cable, which can easily cause the welding front end to separate from the test point, affecting the test progress.

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] For details, please refer to Figure 1 , the test auxiliary device of SSD board includes:

[0029] A fixing plate 1, wherein the fixing plate 1 is connected to the base 2 via a supporting column 3, wherein a nut hole and a cable fixing component are provided on the upper surface of the fixing plate 1; wherein the nut hole and the positioning hole of the SSD board 7 to be tested are correspondingly connected via screws; wherein the cable fixing component is used to fix the test cable; the fixing plate 1 comprises a hollow area, wherein the hollow area is inlaid with a heat sink, and the heat sink is in corresponding contact with the chip position of the SSD board 7 to be tested; and the base 2 comprises a plurality of fans 4.

[0030] The cable fixing component includes a fixing slot 5 and a plurality of butterfly clips 6; the fixing slot 5 includes a cylindrical slot 51, and the diameter of the cylindrical slot 51 matches the diameter of the U.2 connector to PCIE adapter cable.

[0031] The schematic diagram of the separation structure of the test auxiliary device of the SSD board 7 is as follows Figure 2 As shown, it includes a fixing plate 1, a base 2 and a support column 3, and the support column 3 connects the fixing plate 1 to the base 2. The fixing plate 1 includes a fixing slot 5 for the U.2 connector to the PCIE adapter cable, a butterfly clip 6, a nut hole, and a support column mounting hole. The fixing plate 1 is mainly used to fix the SSD card 7, the adapter cable and the differential probe. The base 2 is mainly a heat dissipation device, including two sets of small fans 4. Figure 2 It can be seen that the fixing plate 1 and the base 2 are provided with corresponding support column mounting holes, and the two ends of the support column 3 are clamped in the corresponding support column mounting holes of the fixing plate 1 and the base 2 respectively.

[0032] Among them, fixed slot 5 is as follows Figure 3As shown, the fixed slot of the U.2 connector to PCIE adapter cable fixes the adapter cable in the cylindrical slot 51, and also has a cushioning device to prevent the adapter cable from falling, resulting in poor connection between the SSD and the adapter cable. Specifically, the main body of the cylindrical slot 51 is a cylindrical structure, and the cylindrical structure includes a cylindrical cavity; the cylindrical slot 51 is set at the edge of the short side of the fixed plate 1, and the center line of the cylindrical cavity of the cylindrical slot 51 is perpendicular to the short side; the short side edge is provided with a pad 52, one end of the cylindrical slot 51 is fixedly connected to the pad 52, and the other end of the cylindrical slot 51 is fixedly connected to the fixed plate 1.

[0033] When testing signal integrity, it is usually necessary to test the signal, which requires welding 4 test points and using 4 sets of differential probes. Therefore, 4 sets of butterfly clips 6 are designed. The cables of the differential probes are fixed by the butterfly clips 6 so that the welding front end and the cables can be stably fixed on the SSD board 7. The differential probe has many cables inside, which makes the probe have a large torque. It is easy to be twisted slowly during the test. Once twisted, the front end and the welding wire will loosen, causing the welding wire to be disconnected from the measuring point. In severe cases, it may cause the pad to fall off. The butterfly clip 6 can be used to effectively fix the probe and make it stably fixed. Specifically, the structure of the butterfly clip 6 is as follows Figure 4 As shown, the butterfly clip 6 is connected to one end of the telescopic rod 61, and the other end of the telescopic rod 61 is provided with a thread. The telescopic rod 61 passes through the fixing plate 1 and is connected to the screw hole corresponding to the base 2 through the thread.

In this fan tilting structure, the air ducts of the two fans intersect, covering the entire fixed plate, and accelerating the air flow in the space between the fixed plate and the base, thereby improving the heat dissipation efficiency.

[0036] The side of the first fan close to the first short side is connected to the base through a height adjustment bracket, and the side of the first fan away from the first short side is directly connected to the base through a hinge; the side of the second fan close to the second short side is connected to the base through a height adjustment bracket, and the side of the second fan away from the second short side is directly connected to the base through a hinge.
