Large-capacity memory space - Operating system and GPU parallel computing

  • Windows 8.1 (X64) operation system can expand the memory space and easily deal with the data storage of the whole board shooting and inspection.

Efficient image data processing - GPU

  • GPU is 100 times faster than CPU, easily dealing with the image processing and image detection of the whole board. 

Efficient programming and debugging mode

  • Fast programming and commissioning: By importing CAD data and automatic link detection library to achieve 30min fast programming; GPU-based real-time calculation can achieve 15min to quickly debug the relevant parameters of various algorithms.
  • High accuracy: The whole board shooting and detection technology based on seamless splicing can effectively avoid detection errors caused by differences in mechanical accuracy.
  • Strong stability: Calibration based on pre-shipment and periodic optical white balance, optical resolution, optical distortion, splicing accuracy, display color, fully guarantees the stability of the detection performance.

For improving the efficiency of the entire plant through -  SPC management system 

  • Achieving the efficiency of the entire factory through powerful SPC management system
  • The ultra-high accuracy in determining errors to ensure inaccurate inspection ratio can be controlled within 3000PPM.
  • SPC Report: The user-friendly report function can trace the data information of each PCB test, at the same time, it can query the bad product information of a certain period of time and connect with the shop floor system to achieve higher quality monitoring and management.
  • Ultra-low false positive rate: The unique image processing theory can filter out the factors that may have an impact on the detection results, ensuring unnecessary interference in the detection process, thereby reducing the misjudgment and improving the detection efficiency.
