Description

Technical Field

[0001] The utility model belongs to the technical field of chip processing, and particularly relates to a packaging clamping device for chip packaging equipment. Background Art

[0002] Traditional chip packaging can be summarized into five steps: grinding, cutting, loading, bonding and plastic sealing. The loading and plastic sealing process is the packaging process. The wafer obtained in the grinding step is polished to become a wafer of suitable thickness, and then a wafer is cut into hundreds of chip dies. At this time, the cut chips will be attached to a layer of tape. At this time, the chips need to be removed from the tape for the next step of loading. Because the chip is very small and fragile, the chip is generally lifted up from the bottom of the tape with a pin structure, and a vacuum suction cup is set above the tape to adsorb the chip.

During the clamping process, the device needs to completely align the chip with the mounting slot. The clamping operation can only be performed when the chip is completely embedded in the mounting slot. However, since the area of ​​the chip is generally small, the processing efficiency is low.
