Automatic PCB inspection system based on virtual instruments

These years, with the development of more complicated manufacturing method and new electronic component are developed, the quality and performance in production line can no more be well monitored by only visual inspection. On the basis of Virtual Instruments technique, a new system is developed to construct a reliable inspection and control system. This system can find defections such as missing, converting, and inclining in PCB automatic. It will highly upgrade the inspection speed and precision, contrasted to traditional way of visual-inspection. This system is flexible, easy to be extended, thus greatly deducing the cost.
