Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor testing devices, and in particular to an automatic testing machine for semi-finished SSDs. Background Art

[0002] Solid-state drive (SSD) is a storage product that uses semiconductors as its main storage medium and has the same appearance and data transmission interface as traditional HDDs. The working principle of SSD is to record data by using the polarity of specific magnetic particles. When reading data, the magnetic head converts the different polarities of the magnetic particles into different electrical pulse signals, and then uses a data converter to convert these raw signals into data that can be used by the computer.

[0003] In light of the above, it should be noted that traditional SSD testers lack data monitoring of the regional heating and cooling efficiency of semi-finished SSD products during use. This results in high-load operation and high-temperature accumulation in localized areas of the SSD semi-finished products. This causes the service life of some electronic components with low heat resistance to be lower than the average lifespan, and makes parts in these areas more susceptible to damage. Traditional SSD testers are only used for testing in a single environment, and have defects in detecting the heat resistance, cold resistance, and durability of SSD semi-finished products.

That is, the collected object is compared with pre-stored data, and a relevant rating signal is obtained based on the result. Based on this, the relevant components are controlled to perform compensatory operations, thereby adjusting the abnormal temperature rise and temperature drop fluctuations of the SSD body, so that the tester can understand the layout defects of the electronic components on the SSD body and the regional temperature control requirements in real time, and solve the technical problems raised by the background technology.

DETAILED DESCRIPTION

[0040] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] Embodiment 1: This embodiment is used to address the problem that traditional SSD testing machines lack data detection of the regional heating and cooling efficiency of the SSD semi-finished product body during use, which leads to high-temperature accumulation in local areas of the SSD semi-finished product due to high-load operation, causing the service life of some electronic components with low heat resistance to be lower than the average lifespan, and making parts in this area more susceptible to damage.

[0042] See also Figure 1 - Figure 8 As shown, this embodiment is an automatic testing machine for SSD semi-finished products, including a testing machine 1, a center groove 102 is formed in the center depression on the top of the testing machine 1, a transmission kit 104 is provided at the bottom of the center groove 102, a dust accumulation groove 106 is formed in the depression on one side of the bottom of the center groove 102, and dust accumulation grooves 107 connected to the dust accumulation groove 106 are formed in the depressions at the bottom of both ends of the center groove 102, a center shaft 7 is inserted into the top of the transmission kit 104, and a plurality of telescopic cylinder arms 705 are arranged in a circular array on the outer wall of the middle of the center shaft 7, and the bottom of the center shaft 7 is provided with a plurality of telescopic cylinder arms 705. A partition pad 6 is slidably sleeved on the outer wall of the part; a gantry 601 is provided on the top of the partition pad 6, and a partition sealing plate 603 is slidably installed inside the gantry 601. A U-shaped frame 8 is installed on the outer wall of the gantry 601. The U-shaped frame 8 includes a short U frame 801 and a long U frame 802. A sliding air frame 803 is provided inside the short U frame 801, and a heater 806 is installed inside the long U frame 802. An observation top cover 4 that is clamped with the top of the test machine 1 is provided above the partition pad 6, and a control panel 3 close to the observation top cover 4 is embedded in a corner of the top of the test machine 1;

[0043] The control panel 3 is internally provided with a processor, a data acquisition module, a self-test feedback module, and a signal execution module; the data acquisition module is used to collect the surface temperature fluctuation value QEi and the surface temperature fluctuation value WEi of the SSD semi-finished product within the time threshold, and send the surface temperature fluctuation value QEi and the surface temperature fluctuation value WEi to the self-test feedback module via the processor, and set 15 minutes within the detection operation time period of the SSD semi-finished product as the time threshold;

[0044] It should be noted that: the surface area temperature fluctuation value QEi is expressed as the temperature change of the electronic components and circuit boards in the local area of the SSD surface within the time threshold, and the value of the surface area temperature fluctuation value QEi reflects the use load of the electronic components in this area and the service life affected by temperature. The larger the value, the greater the use load of the area and the higher the temperature control accuracy required for the electronic components in this area. The surface area temperature reduction presentation value WEi is expressed as the arrangement of electronic components on the circuit board in the local area of the SSD surface under high load temperature rise within the time threshold, and the size of the influence of the external cooling structure on the surface temperature, and the value of the surface area temperature reduction presentation value WEi The size of reflects whether the arrangement of electronic components on the circuit board in that area is reasonable, as well as the cooling demand for the external cooling structure. A larger value indicates a more unreasonable arrangement of electronic components on the circuit board in that area, and a greater cooling demand from the external cooling structure. Furthermore, table i represents a sequence mark after the SSD semi-finished surface circuit board is divided into equal areas, and i is a positive integer greater than zero. The surface area temperature fluctuation value QEi is collected by temperature sensor 1 located on the inner wall of the U-shaped frame 8 and on the chuck 706. The surface area temperature reduction presentation value WEi is collected by temperature sensor 2 located on the chuck 706 and the inner wall of the observation cover 4.

[0045] After receiving the body surface temperature fluctuation value QEi and the body surface temperature fluctuation value WEi, the self-test feedback module immediately analyzes the programming stress resistance efficiency of the semi-finished SSD. The specific analysis process is as follows:

[0046] Obtain the temperature fluctuation value QEi and the temperature fluctuation value WEi of the surface area of the SSD semi-finished product within the time threshold, and use the formula Obtaining a burn-in pressure resistance coefficient Gp, where a and b are proportional coefficients of the body surface temperature fluctuation value QEi and the body surface temperature fluctuation value WE, respectively, and a>b>0, Gp is expressed as the burn-in pressure resistance coefficient, and immediately retrieving a stored preset burn-in pressure resistance coefficient Yp from the processor for comparison and analysis with the burn-in pressure resistance coefficient Gp;

[0047] If the burning pressure resistance coefficient Gp is less than or equal to the preset burning pressure resistance coefficient Yp, it is determined that the SSD semi-finished product has a test abnormality, and an adjustment signal is generated. The generated adjustment signal is sent to the signal execution module via the processor. After receiving the adjustment signal, when the SSD semi-finished product is located in the dust-throwing simulation chamber, the signal execution module immediately controls the heater 806 to work, and the heater 806 reduces the heating inside the U-shaped frame 8. The exhaust fan 406 is connected to the electric nozzle 403 via a pipeline, and the arc-shaped spray rack 402 is driven by the sliding cylinder 401 to approach the long U-frame 802 until the electric nozzle 403 approaches the SSD semi-finished product limited by the clamping plate 706 and the telescopic clamp 707. The electric nozzle 403 outputs partial airflow to the semi-finished product in a regionalized manner, prompting the airflow to cool different areas of its surface with different air pressures, thereby reducing further damage to the SSD semi-finished product and retaining the abnormal state for subsequent targeted observation and understanding.

[0048] If the burning resistance coefficient Gp>the preset burning resistance coefficient Yp, no signal is generated.
