Description

Technical Field

[0001] The utility model belongs to the technical field of chip detection, and relates to a camera unit for detecting the bottom surface and edges of a chip component. Background Art

[0002] After the chip is produced, it is necessary to detect the bottom surface and edges of the chip to determine whether there are defects in the chip. Usually, a detection camera is used to take pictures of the bottom surface of the chip. However, in order to better capture the image when the detection camera takes pictures, the lens of the detection camera often faces the bottom surface of the chip directly. This results in the detection camera being unable to accurately capture the image of the chip edge, making it impossible to effectively detect the chip edge. The quality of the chip edge has an important impact on the overall performance and reliability of the chip. Minor damage or deformation of the edge may cause problems during chip packaging, soldering, etc., thereby affecting the stability and lifespan of the chip. Summary of the Utility Model
