Description

Technical Field

[0001] This utility model relates to the field of chip testing, and in particular to an automatic appearance testing mechanism. Background Technology

[0002] Chip appearance inspection is a critical quality control step in the later stages of chip manufacturing and packaging. Its core is to use visual recognition technology to accurately identify physical defects on the chip surface and packaging structure, ensuring that the chip appearance meets design standards and usage requirements, and avoiding problems such as abnormal electrical performance and decreased reliability caused by appearance defects.

[0003] Existing automatic appearance inspection mechanisms mostly use industrial cameras to inspect chips and then send instructions to a telescopic rod to push off defective chips. These chips may be defective in appearance but can still be used after modification. However, the telescopic rod may damage them, resulting in a loss of economic benefits.

[0004] To this end, we propose a device for controlling the falling of defective chips and reducing the possibility of damage to their bodies. Utility Model Content
