Koh-Young Zenith 3D AOI

A new family of Automated Optical Inspection (AOI) systems, is incorporating a revolutionary new 3D approach. The new Zenith system is based on technology which ‘breaks the 2D’ AOI inspection barrier by incorporating the ability to, in addition to full conventional 2D capability, sense and measure Z-axis of whole assembled PCB.

Key Features

  • Uses patented 8-way projection technology and multi-frequency height measurement
  • True measurement of the 3rd dimension
  • Flags and quantifies all defects
  • Intuitive programming using 3D measurement
  • Total IPC 610 Compliance Solution
  • The Perfect Warp Compensation Solution


The Zenith 3D AOI System inspects the following items:

  • Missing
  • Offset
  • Rotation
  • Polarity
  • Upside Down
  • OCV
  • Coplanarity
  • Solder Fillet
  • Lifted Lead
  • Billboarding
  • Tombstone
  • Bridging
