YesTek Automated Optical Inspection

The economic realities of quality control, rework cost and need for customer confidence make Automated Optical Inspection (AOI) a necessity in Circuit Board manufacturing environments AOI can take a number of rolls on the PCB production line. There are a number of “captive” applications such as accurate component positioning in the pick and place system, or screen checking in the paste printer, and there are also stand-alone functions to which AOI is ideally suited.

YesTek ScanSpection AOI uses two basic algorithm groups to inspect component and soldering. The first algorithm checks the component related parameters at once, with these being entered to a Model training phase. The second algorithm group is for solder and lead inspection and offers the ability to use the optimum algorithm for the type of inspection to be carried out. In addition the solder inspection and lead inspection can be attached to a package type rather than component type to assist in programming.
