AI Technical Summary
Technical Problem
Existing chip positioning fixtures have low positioning accuracy and are prone to jamming when faced with pin size deviations and encapsulated burrs, which affects chip quality.
Method used
A chip precision positioning fixture was designed, which uses ribs to avoid the pins, and combines the pin edges and non-pin edges with chamfering for positioning. An avoidance area is set to facilitate operation, and the positioning groove structure is gradually narrowed to ensure gap matching.
Benefits of technology
It improves chip positioning accuracy, avoids movement when the chip is too small and jamming when the chip is too large, and makes operation convenient.

Abstract
The utility model discloses a chip accurate positioning jig, the chip is provided with a colloid, the colloid is provided with a pin edge and a non-pin edge, the pin edge is provided with a pin, the chip accurate positioning jig comprises a jig main body, the jig main body is provided with a positioning groove, a colloid supporting boss is arranged in the positioning groove, and the non-pin edge is provided with a non-pin edge. The edge of the colloid supporting boss is provided with a rib matched with the edge of the pin, the outer side of the rib is provided with a pin bearing area, and the rib avoids the pin. According to the utility model, the ribs are arranged to avoid the pins, and the chip is positioned through the pin edge chamfers and the non-pin edge chamfers, so that the problem that the chip moves when the chip is too small or is blocked when the chip is too large can be avoided, the mode is novel, and the positioning precision is high; and meanwhile, an avoiding area is arranged, so that a worker can take and place the chip more conveniently.
