The traditional manufacturing industry composed of a large number of manual labor will lose its previous advantages and face various new problems under the background of industry 4.0 and the promotion of science and technology
With the development of higher density, smaller size, and more complex PCB hybrid technology for electronic assembly, the inspection of post-print quality with the naked eye is a thing of the past.
Due to the miniaturization of components, it is difficult to repair the defects of micro-miniature components after welding, and the defects of components cannot be repaired basically.
The electronic plug-in manufacturing process has very strict requirements on the quality of products. For the manufacturing process of hundreds or even thousands of electronic plug-ins per minute, even a high product qualification rate of 1% means huge economic benefits.
Due to the characteristics of the wave soldering process, defects are most likely to occur in this process, such as pin short circuit, virtual soldering, missing soldering, braided soldering, etc.
For the SMT production process, with the increasing precision of the mounted components, the post-furnace AOI has become an indispensable and important member of the SMT production line.
With the rapid development of PCB products in the direction of ultra-thin, small components, high density and fine pitch.
