Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically a memory chip testing fixture. Background Technology

[0002] Chip testing, specifically system-on-a-chip (SoC) testing in the early design stages, is based on deep submicron technology. Therefore, testing SoC devices requires entirely new methods. Since each functional component has its own testing requirements, design engineers must make test plans in the early design stages.

[0003] Patent publication number "CN212060331U" discloses "A memory chip testing fixture, belonging to the field of memory chip technology, which includes a base plate. A pushing device is fixedly connected to the upper surface of the base plate. The upper surface of the pushing device overlaps with the lower surface of the PCB circuit board. A stepper motor is fixedly connected to the upper surface of the base plate, and a support plate is fixedly connected to the output shaft of the stepper motor." This memory chip testing fixture, through the cooperation of the stepper motor, electric push rod, pressure plate, slide rod, and first spring, makes the fixing of memory chips simpler and more convenient, saving time and effort. Furthermore, while fixing the chip, the fixture can stretch the pins to improve their levelness, ensuring better testing of the memory chip. Simultaneously, while testing one memory chip, the operator can continue to position another, further saving considerable time and facilitating the operator's work.

[0004] In the aforementioned patent, the existing test fixture has a limited clamping capacity per clamping, resulting in low testing efficiency during actual use. This affects work efficiency, and clamping multiple chips of different sizes simultaneously is cumbersome, thus affecting the effectiveness of use.

[0005] To address these issues, this invention provides a memory chip testing fixture. Utility Model Content
