PCB Manufacturer in China: AOI Process in PCB Factory

AOI as d detective and test process is very important in quickturn PCB manufacturer factory. Let us see how AOI works in quickturn PCB manufacturer factory.

Main equipment: AOI, VRS system

The copper foil that has formed the line through the AOI system scan detection missing line. The standard line image information is stored in the AOI host in the form of data. The CCD optical image capture head scans the line information on the copper foil into the host and compares it with the stored standard data. When there is an abnormality, the abnormal point position is transmitted to the VRS host by the number record. . . . On the VRS, the copper foil line on quickturn PCB is magnified 300 times, and sequentially displayed according to the disadvantages recorded in advance, and it is judged by the operator whether it is a true quickturn PCB defect, and the water-resistant pen is marked in the defect position for the true defect. In order to facilitate subsequent operators to classify the statistics and repairs the defects. The operator judged with a 150x magnifying glass

Types of PCB defects, classification statistics form quality reports, and feedback to the previous process to facilitate the timely implementation of improved measures. Because the single panel has fewer disadvantages and lower cost, it is difficult to use AOI to interpret, so it is directly inspected by artificial naked eye.
