Abstract

The invention relates to a mechanical shock test fixture for an integrated circuit, which comprises that a base (1), a cover plate (5) and bolts, wherein a positioning groove (2) for containing the integrated circuit is formed in the middle of the base (1); at least two bolt holes (3) are formed in the base (1); a group of wire lead holes (6) matched with the positioning groove (2) in the base is formed in the middle of the cover plate (5); at least two bolt holes (4) matched with the base are formed in the cover plate (5); and the matched bolts (7) are arranged in the bolt holes in the base and the cover plate and connect the base and the cover plate into a whole. The fixture has the advantages that a circuit sample is completely nested into the fixture and completely matched with the fixture, so that the sample does not bear outside stress or slide under the conditions of progress and high acceleration (a peak value exceeding 100,000 g), and the completely actual shock resistance level of the sample is reflected. Shock tests in six directions can be achieved conveniently only by changing the connection direction of a mold, and the direction change is also very simple.

Description

technical field [0001] The invention relates to integrated circuit testing technology, in particular to an integrated circuit mechanical impact test jig. Background technique [0002] The acceleration test is one of the effective means to examine the internal structural strength of integrated circuits, the internal lead strength, the bonding strength of internal components, and the packaging strength. With the continuous expansion of the application range of integrated circuits, the acceleration test of integrated circuits is becoming more and more High (peak value over 100,000 g). [0003] At present, there are mainly two types of acceleration test fixtures: [0004] 1. Patent No.: 201020208344, patent name: Fixture for PCB board vibration and impact test; this patent mainly involves the fixing of PCB board for mechanical impact test. Screw holes and support columns are used to fix the sample. During the mechanical impact test of the microcircuit, since the additional for...
