OptiCheck - Software

OptiCheck-Software follows the principles of image comparison based on most recent methods of colour image processing and recognition.
It works using these steps:
  • the scanner unit, the Scan-box of the TT-System for off-line operation, or the Conveyor-Box of the in-line system scans the board to be checked and offers a two dimensional colour image to the computer for further validation.
  • following a predefined checkplan the system validates the part positions (check areas)using the dimensions and algorithms defined in the library. Like a placement plan of a pick-and-place OptiCheck „knows“, at which position a certain part can be expected.
The part positions can be validated matching these criteria:
  • Existence or absence?
  • Correct colour according to a reference image and tolerance pattern?
  • Exact positioning inside of the tolerance frame?
  • ... inside the accepted rotation tolerance?
  • Existence and position of the polarity marker?
  • Label and markers or parts?
  • Appropriately defined contact spaces are checked additionally for bridges.

OptiCheck-Software is able to recognize:

missing components
wrong components
shifted components
twisted components
edged components
wrong polarity
wrong component mark
bridges
wrong component value
solder quality
missing soldering paste
too small soldering paste on the pad
too much soldering paste around the pad
bridging
