With the in-depth development of higher density, smaller size, and more complex PCB hybrid technology for electronic assembly, it has become history to inspect the printed quality with the naked eye.
Due to the miniaturization of components, it is difficult to repair micro-component defects after soldering, and component defects are basically impossible to repair.
The electronic plug-in manufacturing process has strict requirements on the quality of the product. For the electronic plug-in manufacturing process of up to hundreds or even thousands of kinds per minute, even a 1% higher product qualification rate 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 shorts, false soldering, missing soldering, and brazing.
For the SMT production process, with the increasing precision of placement components, post-furnace AOI has become an indispensable and important member of the SMT production line
