Description

Technical Field

[0001] The utility model relates to the technical field of chip fixing, and more specifically, to a fixing piece for chip packaging. Background Art

[0002] In the existing technology, firstly, some devices cannot reliably clamp and fix the chip, which causes the chip to easily shift or fall off during the packaging process. The fixing state of the chip is unstable, affecting the packaging quality and yield rate. Manual clamping of the chip is inefficient and easily introduces human factors, affecting production consistency.

[0003] Secondly, some devices cannot provide flexible support and clamping, and cannot adapt to chips of different sizes and shapes. The contact rigidity between the chip and the support mechanism is too large, which may cause damage to the chip. The chip is unevenly subjected to force during the packaging process, which is prone to stress concentration and affects the packaging quality. It is impossible to achieve adaptive adjustment of the clamping force and cannot meet the clamping requirements of different chips. Finally, some devices cannot achieve height adjustment of the flexible support mechanism and cannot adapt to chips of different thicknesses. The stability and reliability of the support mechanism are reduced, affecting the clamping and support performance. The locking and unlocking mechanisms lack guidance and support, and the movement smoothness and positioning accuracy are reduced. Utility Model Content
