FPD inspection system 'Capricorn series'

Capricorn series
[Overview] Capricorn is the defect inspection system and achieves many defect inspections in the FPD manufacturing process, especially in LCD manufacturing process.
This system detects various defects that occur in each FPD manufacturing process and serves to control quality of mass production line.
[Features]
  • High defect detectability
  • Various types of defects can be caused in panel/substrate and all of them are met necessary to detect as Quality Control management. To focus on critical defects which are relate to panel quality defects, this system adopts inspection camera, image processing system and machine mechanism optimized to defect clarified defects for each LCD manufacturing process and achieves defect inspection with high accuracy. It results in avoiding the detection of artificial defects which make it difficult to inspect and inspecting defects for a short time.
  • High operability and reliability
  • This system is design to consider operability and reliability and achieves safe and user-friendly operation and stable running.
  • 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.
