[0053] The entire integrated circuit environmental testing equipment requires high and low temperature resistance and oxidation resistance. 304 stainless steel is selected and quenched (anti-oxidation) treatment is performed to ensure that the material itself will not be corroded and cause product contamination.

[0054] Working principle:

[0055] Preparation of Carrier Unit 1: As the basic structure of the entire device, the carrier unit 1, with its slots around the perimeter and the bottom slot 32, is crucial for the subsequent installation of the blade clamp unit 2. The mesh-like perforated design of the slot 11 not only provides good temperature uniformity and air permeability for the experiment but also allows for better airflow during the experiment, ensuring a uniform and stable ambient temperature for the sample. Meanwhile, the handle 13 facilitates the operator's handling and movement of the carrier, while the positioning hole 14 provides an accurate positional reference for the subsequent installation of positioning posts and stacking of the carrier.

[0056] Installation of the knife holder unit 2: Select the appropriate number and specifications of upper knife holders 21 and lower knife holders 22 according to the size of the sample. First, fix the lower knife holders 22 in place using the slots 32 at the bottom of the groove 11, ensuring that the shape and size of the lower knife holders 22 and the slots 32 are perfectly matched, and that the latches on the lower knife holders 22 correspond one-to-one with the latches on the groove 11 in position and size. Then, install the upper knife holders 21 above the lower knife holders 22, ensuring that the latches on the upper knife holders 21 and the latches on the lower knife holders 22 accurately correspond from the first latch to the last latch, forming acupoints for placing the sample. The combinability of the upper knife holders 21 and lower knife holders 22 allows the device to adapt to samples of different sizes, improving the versatility and flexibility of the device.

[0057] The function of connecting unit 3: The tight fit between the slot 32 and the bayonet ensures a stable connection between the upper and lower tool holders 21 and the carrier plate unit 1, preventing the tool holders from becoming loose or shifting during the test. The stepped positioning support column 31 plays a crucial role in connecting the upper and lower tool holders 21 and the stacked multi-layer carriers. Its two ends precisely match the positioning holes 14 on the upper and lower surfaces of the slot 11, and the stepped structure in the middle stably supports the other carrier stacked above, enabling the stacking of multiple test devices, saving space, and ensuring the stability and safety of the stacking.

[0058] Experimental process principle

[0059] Sample Placement and Isolation: The integrated circuit sample to be tested is placed in the acupoint consisting of the acupoint base plate 12, the upper blade holder 21, and the lower blade holder 22. The upper blade holder 21 and the lower blade holder 22 isolate each sample, avoiding scratches, bending, and breakage caused by collisions and stacking between samples during the test. This effectively protects the integrity and performance of the samples, ensuring the accuracy and reliability of the test results.

[0060] Environmental Simulation and Testing: During the experiment, the entire device was placed in a specific environmental test chamber, such as a high and low temperature test chamber or a humidity test chamber. Due to the mesh-like perforated design of carrier plate unit 1 and the excellent properties of 304 stainless steel, the device can maintain stable performance under different environmental conditions and can respond quickly and uniformly to changes in ambient temperature and humidity, making the environmental conditions of the samples closer to the extreme environments in actual use. Simultaneously, the high-temperature, low-temperature, and oxidation-resistant 304 stainless steel, after quenching treatment, effectively prevents corrosion of the material itself in harsh environments, avoiding contamination of the samples due to material corrosion and ensuring the authenticity and repeatability of the test results.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
