Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be clearly and completely described in the following in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A die-bonding jig according to an embodiment of the present utility model will be described in detail with reference to fig. 1 to 5.

Examples:

the embodiment of the utility model provides a jig for chip loading, which is shown by referring to figures 1, 2 and 3, and comprises a bottom plate 1, wherein the top of the bottom plate 1 is fixedly connected with a supporting frame 2, the top of the supporting frame 2 is fixedly provided with a chip supporting plate 3, the supporting frame 2 is rotationally connected with two screws 4, a plurality of sections of external threads 5 are arranged on the screws 4, each section of external threads 5 is in threaded connection with two moving plates 6, a plurality of positioning plates 7 are arranged on the moving plates 6, chip positioning grooves 8 are formed between every four positioning plates 7, and the chip carrier is positioned by the chip positioning grooves 8 formed by the positioning plates 7, so that the chip and the carrier are ensured to be accurately assembled;

in use, an operator can rotate the screw 4 to drive the moving plate 6 to move, and the moving plate 6 drives the positioning plates 7 to move, so that the distance between the positioning plates 7 is adjusted, the use can be freely adjusted according to the size of the chip carrier, and the universality of the whole jig is improved.

Referring to fig. 3, the screw 4 is arranged in a vertically staggered manner, the moving plate 6 is arranged in a vertically staggered manner, and structural interference is avoided due to the crisscross design.

Referring to fig. 3, each section of external thread 5 includes two sections of threads with opposite directions, and the threads with opposite directions can drive two moving plates 6 on each section of external thread 5 to move in opposite directions, so as to adjust the distance between the positioning plates 7.
