SMT offline AOI machine
In SMT production line, the equipment in different links plays different roles. Among them, the automatic optical detection equipment SMT AOI is scanned by optical method to read the images of devices and solder feet through the CCD camera, and to detect the solder paste, solder joints and electronic components on the PCBA board through the logical algorithm or image comparison method, so as to find out whether there is deviation, missing installation, short circuit and other defects of the equipment.
Significance of AOI machine in SMT production:
Due to our subjectivity in the process of manual inspection, the results are biased. Therefore, we will introduce AOI equipment in the electronic production process to carry out a comprehensive PCBA board inspection, but also improve the production efficiency and through-rate. Especially for high density and complex surface mount PCB, relying on manual eye inspection is neither reliable nor economical.
At the same time, with the refinement of PCB line graphics used in surface assembly technology, the miniaturization of SMC/SMD components, and the development trend of high-density and rapid SMA assembly, we must use AOI equipment.
AOI testing equipment has the following advantages:
- Solved the structural inspection problem of micro-encapsulated devices to ensure production quality;
- Improve the back-end test pass rate, reduce maintenance costs;
- With the development of technology, AOI testing procedures are fast and simple, which reduces a large amount of testing costs required by production.
Modern electronic processing plants to the direction of science and technology development, enterprises need to continue to introduce a variety of equipment in line with their own development, improve the efficiency of production, save production costs, only progressive enterprises can survive in the competitive environment.
