FPD macro review system 'Asteroid II series'

Asteroid II series
[Overview] In the FPD manufacturing process, some defects can be detected only by the human eye, not by machine.
AsteroidⅡ was developed to support the visual inspection efficiently and allow inspector to defect inspection without overlooking.
  • Light source for various observations to shorten inspection time
  • This system implements various unique optical systems for illumination to facilitate visual inspection and enables shortening observation time.
  • Immediate use of inspection data base for quality control
  • This system provides inspection data to utilize directly for quality control by online system. Quality Controller can grasp quality issue in real time by online system and allow QC to take action efficiently.
  • Microscope observation function
  • This system provides observing defect areas with a microscope.
  • LCD related
  • Glass substrate : Glass substrate inspection
  • TFT substrate : TFT mura inspection, Visual inspection after development, Visual inspection after etching
  • CF substrate : Color filter visual inspection
  • TFT/CF substrate alignment (CELL process) : Alignment layer visual inspection
