Description

Technical Field

[0001] The utility model belongs to the field of chip testing platforms, and in particular relates to a chip testing platform with a dust removal function. Background Art

[0002] In the modern semiconductor industry, chip testing is a critical link in ensuring product quality and performance. However, traditional chip testing platforms often ignore the dust problem on the chip surface during the testing process. The presence of dust and tiny particles may have a negative impact on test results and even lead to test failure or misjudgment.

[0003] During production, transportation, and storage, chips are easily contaminated by dust and tiny particles in the environment. These contaminants can adhere to the chip surface, forming a thin layer of dirt, which can affect the electrical connection between the chip and the test equipment. Furthermore, dust can interfere with the transmission of test signals, resulting in inaccurate or unstable test results. Existing test platforms often struggle to effectively remove dust from the chip's exterior surface during chip appearance inspections, and are unable to quickly flip the chip to inspect both sides. This requires further improvement.

[0004] Therefore, a chip testing platform with a dust removal function is proposed. When inspecting the chip appearance, the dust on the outer surface of the chip can be effectively removed, the chip can be quickly flipped over, and the appearance of both sides of the chip can be quickly inspected.
