Description

Technical Field

[0001] The utility model belongs to the technical field related to chip burning, and specifically relates to a double-point chip positioning mechanism in a track. Background Art

[0002] Chip burning refers to the process of writing programs or data into a chip. Specifically, when a chip is working, it needs a program to miniaturize all components into one or several integrated circuits, and these programs need to be stored in the chip by burning. This process is mainly completed by a burner, which can import the written program into the target chip to realize the different functions of the chip. Therefore, chip burning is one of the important steps to realize the chip function. During the chip burning process, in order to make the chip effectively cooperate with the test needle, the chip needs to be positioned. The existing positioning method is single cylinder positioning (see attached Figure 5 ) There is linear contact between the chip and the cylindrical positioning cylinder, which causes the chip to offset and swing, affecting the matching accuracy between the chip and the test needle, and requires manual intervention and correction.

[0003] In view of this, the present utility model is proposed. Utility Model Content
