Description

Technical Field

[0001] The present invention relates to the field of flash memory particle production equipment, in particular to a flash memory particle screening equipment. Background Art

[0002] With the rapid development of information technology, flash memory particles, as an important medium for data storage, are of vital importance for the stable operation of electronic devices. Flash memory particles are widely used in products such as solid-state drives, USB flash drives, and memory cards, and their performance directly affects the reliability and service life of these devices. However, in the production process of flash memory particles, due to factors such as materials and processes, it is inevitable that some particles with appearance defects or unqualified performance will appear. If these defective particles flow into the market, they will not only affect the performance of electronic devices, but may also cause unnecessary losses to consumers.

[0003] Traditional flash memory particle screening methods mainly rely on manual detection, which has the following problems:
