A pcb board online semiconductor device testing system

Abstract

The present invention relates to the technical field of PCB boards, in particular to an online semiconductor device testing system for PCB boards, which includes a placement table, a slide bar, a slide sleeve, a telescopic spring, a movable bar, a limit plate, a post, a slide rail, a slide block, an extrusion Compression spring, limit column, rope, adjusting screw, lock nut, guide rail, movable block, needle bed and testing system, the bottom of the inner wall of the placement table is provided with a chute, and the middle position on both sides of the inner wall of the chute The two ends of the sliding rod are respectively fixedly connected, and the two sliding sleeves are respectively socketed with the outer surface of the sliding rod, and the sliding sleeves are slidably connected with the sliding rod. The invention achieves the purpose of being applicable to the clamping and positioning of PCBs of different sizes, and at the same time, the overall structure is simple and convenient, and can be automatically changed according to its size, thereby replacing the previous way of detecting PCBs that needs to be replaced according to the model, thus improving the detection efficiency. , which simplifies the inspection process and meets the clamping requirements in the PCB inspection process.

Description

technical field [0001] The invention relates to the technical field of PCB boards, in particular to a PCB board online semiconductor device testing system. Background technique [0002] Circuit boards have become an important part of today's electronic products. With the development of electronic technology and printed circuit board manufacturing technology, modern electronic products are becoming more and more complex, and the density of printed circuit boards is increasing. Testing and repairs are also more difficult. In order to improve the automation degree of inspection and maintenance of printed circuit boards, it is very necessary to design an automatic test system for circuit boards. [0003] At present, the equipment for automatic detection of PVB boards is mainly a functional tester, which ensures that the performance of the PCB board is normal through systematic detection. However, during the detection process of the PCB board, the clamping action of the entire P...

Problems solved by technology

[0003] At present, the equipment for automatic detection of PVB boards is mainly a functional tester, which ensures that the performance of the PCB board is normal through systematic detection. However, during the detection process of the PCB board, the clamping action of the entire PCB board is not There is no suitable fixture to match it, and each fixture is suitable for its corresponding model, so in the process of testing different types of PCB boards, the assembly efficiency is reduced, and the fixtures used cannot be compatible with most fixtures Therefore, the inspection efficiency is reduced, the entire inspection process is cumbersome and complicated, and at the same time, the work efficiency is significantly reduced, so it cannot meet the work requirements.
