Description

Technical Field

[0001] This utility model belongs to the field of semiconductor integrated circuit manufacturing technology, and relates to a device for auxiliary aging test. Background Technology

[0002] Aging life testing is a testing method that simulates the gradual performance degradation of products due to environmental factors during actual use. It helps companies assess the lifespan, reliability, and stability of products under specific environmental conditions, optimize product design, and improve product quality. This test simulates environmental conditions that products may encounter, such as high temperature, low temperature, humidity, and ultraviolet radiation, to accelerate the product aging process, predict product lifespan, reduce early failure rates, and ensure product compliance with industry regulations. It has wide applications in many fields, including electronics, automotive, machinery, aerospace, and medical. Aging life testing not only assesses product reliability and stability but also predicts performance loss over its lifespan, identifies design flaws or manufacturing problems, optimizes product design and processes, improves product quality, and explores product aging mechanisms, providing a scientific basis for material improvement and replacement.

[0003] When conducting aging tests, samples are usually tested in batches, and the testing device is in a continuous working state. When conducting high-temperature accelerated aging tests, if the device is placed directly into the high-temperature testing device, the sample will be directly introduced from the room temperature environment into the high-temperature environment. The rapid temperature change in a short period of time will affect the performance of the product, making its working state unstable, which will lead to deviations in the experimental data.

[0037] Please see Figures 1 to 3 ,in, Figure 1 The diagram shown is a structural schematic of the device for assisting aging tests according to this invention. Figure 2 The image shown is a cross-sectional view of the device for assisting aging tests according to this invention on the XZ plane. Figure 3The diagram shows a cross-sectional view of the device for assisting aging tests according to this invention on the YZ plane. The device includes a housing 1, a workbench 2, a first chamber door 6, a second chamber door 7, a first heating wire 8, a second heating wire 9, a first circulation box 10, a first air inlet, a first air outlet 11, a second circulation box 13, a second air inlet, a second air outlet 14, a first connecting pipe 16, a second connecting pipe 17, a first airflow circulation assembly, and a second airflow circulation assembly. The housing 1 is mounted on the workbench 2, and a partition plate 3 is provided inside the housing 1, dividing the housing 1 into a first working chamber 4 and a second working chamber 5. The first chamber door 6 is movably connected to one side of the first working chamber 4, and the second chamber door 7 is movably connected to one side of the second working chamber 5. The first heating wire 8 is disposed on an inner wall of the first working chamber 4, and the second heating wire 9 is disposed on an inner wall of the second working chamber 5. The first air inlet and the first air outlet 11 are located in the first working chamber 4. The first circulation box 10 is located outside the first working chamber 4 and communicates with the first working chamber 4 through the first air inlet. A first return air inlet 12 is provided on the side of the first circulation box 10 away from the first working chamber 4. The second air inlet and the second air outlet 14 are located on opposite side walls of the second working chamber 5. The second circulation box 13 is located outside the second working chamber 5 and communicates with the second working chamber 5 through the second air inlet. A second return air inlet 15 is provided on the side of the second circulation box 13 away from the second working chamber 5. The first end of the first connecting pipe 16 is connected to the first air outlet 11, and the second end of the first connecting pipe 16 is connected to the first return air inlet 12. The first end of the second connecting pipe 17 is connected to the second air outlet 14, and the second end of the second connecting pipe 17 is connected to the second return air inlet 15. The first airflow circulation assembly is located inside the first circulation box 10, and the second airflow circulation assembly is located inside the second circulation box 13.

[0038] As an example, the housing 1 may be bottomless, in which case the workbench 2 can be used to enclose the housing 1.

[0039] For example, please refer to [link / reference]. Figure 2The first airflow circulation assembly includes a first motor 18, a first rotating shaft 19, and a first fan blade 20 connected sequentially in the direction from the first return air inlet 12 to the first air inlet. The second airflow circulation assembly includes a second motor 21, a second rotating shaft 22, and a second fan blade 23 connected sequentially in the direction from the second return air inlet 15 to the second air inlet. When the first airflow circulation assembly is working, the first motor 18 drives the first fan blade 20 to rotate through the first rotating shaft to generate airflow. The airflow is blown out from the first air outlet 11 and enters the first return air inlet 11, and returns to the first circulation box 10 through the first connecting pipe 16 connected to the first return air inlet 11. This achieves internal airflow circulation within the first working chamber 4, ensuring uniform internal temperature distribution and preventing the temperature from being high on the side near the heating wire and low on the side away from the heating wire within the first working chamber 4. Similarly, when the second airflow circulation component is working, the second motor 21 drives the second fan blade 23 to rotate through the second shaft to generate airflow. The airflow is blown out from the second air outlet 14 and enters the second return air outlet 15. It then returns to the second circulation box 13 through the second connecting pipe 17 connected to the second return air outlet 15, which can also realize the internal circulation of airflow in the second working chamber 5 and ensure uniform internal temperature distribution.

[0040] Specifically, before conducting the high-temperature test, the product under test is first preheated using auxiliary aging test equipment. The first working chamber 4 and the second working chamber 5 are set to different temperatures. The product under test is first placed in the lower-temperature working chamber for the first preheating (either the first working chamber 4 or the second working chamber 5), and then transferred to the higher-temperature working chamber for a second preheating. This method gradually preheats the product under test, preventing it from being directly transferred from a room temperature environment to a high-temperature environment before entering the testing equipment for aging tests. This prevents rapid temperature changes from affecting product performance, improves the stability of the equipment, and effectively reduces deviations in experimental test data.

[0041] Specifically, during multi-batch product aging tests, the first batch of products to be tested is placed in a low-temperature chamber for initial preheating. After a period of preheating, they are removed and placed in a high-temperature chamber for a second preheating. Simultaneously, the second batch of products to be tested is placed in a low-temperature chamber for its first preheating. Once the first batch of products has completed its second preheating in the high-temperature chamber, it is sent to the testing equipment for aging tests. At this point, the second batch of products is transferred from the low-temperature chamber to the high-temperature chamber for a second preheating, and then the third batch of products to be tested is placed in the low-temperature chamber. This method enables batch testing with gradually increasing temperatures.

[0042] For example, please refer to [link / reference]. Figure 3The first working chamber 4 is provided with a first mounting groove 24 on one inner side wall, and the first heating wire 8 is installed in the first mounting groove 24. The second working chamber 5 is provided with a second mounting groove 25 on one inner side wall, and the second heating wire 9 is installed in the second mounting groove 25.

[0043] As an example, the first working cavity 4 is provided with a first blocking component and a second blocking component. The first blocking component is disposed at the opening of the first mounting groove 24 and includes multiple spaced first blocking strips 26. The second blocking component is disposed on the side of the first blocking component away from the first heating wire 8 and includes multiple spaced second blocking strips 27. The orthographic projection of the second blocking component on the plane where the first blocking component is located at least blocks the gaps between multiple first blocking strips 26.

[0044] As an example, the second working cavity 5 is provided with a third barrier component and a fourth barrier component. The third barrier component is disposed at the opening of the second mounting groove 25 and includes multiple spaced third barrier strips 28. The fourth barrier component is disposed on the side of the third barrier component away from the second heating wire 9 and includes multiple spaced fourth barrier strips 29. The orthographic projection of the fourth barrier component on the plane where the third barrier component is located at least blocks the gaps between multiple third barrier strips 28.

[0045] Specifically, the first heating wire 8 and the second heating wire 9 are energized to convert electrical energy into heat energy, releasing heat to raise the temperature inside the first working chamber 4 and the second working chamber 5. The hot airflow generated by the first heating wire 8 enters the first working chamber 4 through the gap between the first barrier strip 26 and the second barrier strip 27. The first barrier strip 26 and the second barrier strip 27 can prevent the first heating wire 8 from directly shining on the product under test, avoiding local overheating of the product under test due to direct exposure. The hot airflow generated by the second heating wire 9 enters the second working chamber 5 through the gap between the third barrier strip 28 and the fourth barrier strip 29. The third barrier strip 28 and the fourth barrier strip 29 can also prevent the second heating wire 9 from directly shining on the product under test, avoiding local overheating of the product under test due to direct exposure.

[0046] For example, please refer to Figure 4The diagram shows the structure of the device for assisting aging tests according to this invention after removing the first cavity door 6. The device for assisting aging tests also includes a first temperature display screen 30 and a second temperature display screen 31. One end of the first temperature display screen 30 is connected to a first thermometer probe 32, which passes through a first through hole 33 on the side wall of the first working cavity 4 to enter the first working cavity 4. One end of the second temperature display screen 31 is connected to a second thermometer probe, which passes through a second through hole on the side wall of the second working cavity 5 to enter the second working cavity 5.

[0047] Specifically, the first thermometer probe 32 and the second thermometer probe are respectively installed in the first working chamber 4 and the second working chamber 5 to detect the temperature and display the detected temperature value on the first thermometer display screen and the second thermometer display screen. By observing the values ​​on the first thermometer display screen and the second thermometer display screen, the temperature in the two working chambers can be adjusted to achieve the preheating temperature required for the aging test.

[0048] For example, please refer to [link / reference]. Figure 4 The first working chamber 4 is provided with a first rotating shaft 34, and one end of the first chamber door 6 is sleeved on the first rotating shaft 34. The second working chamber 5 is provided with a second rotating shaft, and one end of the second chamber door 7 is sleeved on the second rotating shaft.

[0049] As an example, such as Figure 2 As shown, a first protective net 35 is provided at the connection between the first working chamber 4 and the first circulation box 10, and a second protective net 36 is provided at the connection between the second working chamber 5 and the second circulation box 13. The first protective net 35 is used to protect the first fan blade 20, and the second protective net 36 is used to protect the second fan blade 23.
