Description

Technical Field

[0001] The utility model belongs to the technical field of memory stick and memory chip testing, and in particular relates to a two-stage double-stroke sliding cover fixture for chip testing. Background Art

[0002] In the industry, a memory chip test device refers to a test board with a chip mounting position on it. This mounting position is equipped with a structure (test fixture) for pressing the chip so that the memory chip connects to the test board contacts. This test device usually simulates a real memory stick, inserts it into the memory slot, and tests the performance. In addition, the number of chip mounting positions on different models of test boards is different, and some models of test boards have as many as 40 chip mounting positions.

[0003] Because the size of the test board is the same as that of the standard memory stick, the size of the test fixture is limited when there are many chip installation positions. The common buckle-type test fixture currently available can only press two chips at a time due to the limitations of strength and manual pressure (a certain friction needs to be overcome when pushing the cover, the more particles are pressed, the greater the friction, and the more force is required to push the cover during operation). This cannot meet the requirements of using test boards with more chip installation positions. Utility Model Content
