Description

Technical Field

[0001] This patent relates to the field of chip packaging, and specifically to a chip detection and tube-to-tape transfer device. Background Art

[0002] Existing chip packaging forms include tape packaging and tube packaging. The tape used in tape packaging can facilitate subsequent chip surface mounting processes, while the tube used in tube packaging is not convenient for subsequent chip surface mounting processes, reducing production efficiency. To improve the chip surface mounting efficiency, it is necessary to change the tube to tape packaging. When changing the tube to tape, there may be vacancies in the tape, which requires detecting the vacancies in the modified tape. If vacancies are found, manual filling is needed.
