Tips


Getting a good REFERENCE

  • Place the green mat under the platform covering all the inspection area and make sure the table is not visible from the camera.
  • Make sure that the PCBA is correctly mounted. This is important because if there is an error on it, it will not be marked on subsequent PCBAs inspected.
  • Avoid using PCBA with contamination. Clean the PCBA before taking the picture

    Contamination

  • Avoid mixing different components with same specifications. The software is not able to "read" the labeling and will mark them even if they have the same specifications. If a component have changed during production make a new REFERENCE image to avoid false positive marking.

  • Avoid taking images with cables or components with high position variability. This would increase the false positive rate.

    REFERENCE: Cables

    UUI: Cables

    Result: Cables

  • Ensure the image has been taken correctly focused and all components looks sharp. If not, repeat the capture.

    Bad focus

  • Ensure there are no objects other than the PCBA in the image.

    Objets

  • Select the correct composition of images to avoid taking unnecessary images and to shorten processing time.

    REF dimensions

  • Do not mix soldered and pre-soldered PCBAs. If you take a picture of a REFERENCE image with soldered components, do not inspect unsoldered UUI PCBAs, it will result in a marking with a very high false positive rate.

  • As with soldered/pre-soldered PCBAs, do not mix coated and uncoated PCBAs.

Making a good inspection

  • Follow the REFERENCE taking tips
  • Place the PCBA to inspect in the same location and position as the REFERENCE PCBA was captured. The live view will display a phantom image of the REFERENCE PCBA to assist with alignment. It is not necessary to place the UUI in exactly the same location as the software corrects the alignment.
