  The present invention relates to a circuit reinspection apparatus, and more particularly to a circuit reinspection apparatus for reinspecting a flexible circuit sheet.

  With the demand for high resolution development, process technology improvement and industrial production automation, the detection method using conventional human visual inspection (MVI) is gradually lacking, generally missing elements, part number classification And only some obvious mistakes can be inspected. Since it is easily affected by artificial, subjective and objective factors, human visual inspection is unstable, difficult and expensive. Accordingly, the invention of an automated optical inspection (AOI) has emerged accordingly.

  In recent years, automatic optical detection equipment is a detection equipment with considerable market potential, and its basic working principle is that the graphic image information of the detected object is mainly obtained by the image sensor, and then the built-in computer It is to perform collation, analysis and judgment by software processing and calculation. As can be seen, automatic optical detection not only reduces the error rate of human visual inspection, but also saves a lot of time and labor costs. Moreover, the automatic optical detection equipment further has merits such as high stability and flexibility in operation.
