Image Sensors Used to Stably Determine Passing or Failure of Workpieces on Rapidly Conveyed Lines

Case Number 233

last update: April 18, 2011

This Image Sensor has improved pattern matching. This also enables handling rapidly moving workpieces such as those in mounting of embossing tape conducted in the latter processes of semiconductor manufacturing. The front and back of electronic components and the difference between different models are measured and in comparison with non-defective items to enable stable detection of mounting errors.


The unique image processing circuits support high-speed lines performs matching with models dividing images into smaller parts. Subtle differences that cannot be determined by conventional pattern matching are detected as large numerical values.

Benefit / Efficiency

Detection of irregularities on embossing tape prevents problems on customer lines and in products.
