Description

Technical Field

[0001] The utility model relates to the field of chip packaging, in particular to a chip continuous disk-to-tape transfer device. Background Art

[0002] The existing chip packaging forms include tape packaging and tray packaging. The chips in tray packaging are not conducive to the subsequent chip surface mounting process, and the production efficiency is relatively low. While the chips in tape packaging can be conveniently used for the subsequent chip surface mounting process with high production efficiency. In order to improve the chip surface mounting efficiency, equipment for converting the chip tray packaging into tape packaging is required. The traditional chip taping process uses a single tape, resulting in low taping efficiency. Therefore, there is a need to develop and design equipment suitable for taping multiple tapes simultaneously.

[0003] In the chip taping process, an important process is the heat sealing between the tape and the plastic film. The traditional heat sealing device uses discontinuous heat sealing. After the heat sealing device completes one heat sealing, the heat sealing knife is lifted, the tape advances a certain distance, and then the heat sealing knife drops to contact the tape for the second heat sealing. This discontinuous heat sealing device has relatively low efficiency. To improve the heat sealing efficiency, a high-efficiency continuous heat sealing device needs to be designed.

[0004] Therefore, how to convert the chip tray packaging into tape packaging and how to achieve high-efficiency taping are technical problems that need to be solved by those skilled in the art. Content of the Utility Model
