What it is
The Koh Young Zenith 2 AOI is an automated optical inspection system for printed circuit board assembly. The Koh Young Zenith 2 AOI belongs to metrology and inspection equipment used on SMT production lines.[2][1]
The Koh Young Zenith 2 AOI performs 3D and 2D inspection. The Koh Young Zenith 2 AOI is part of Koh Young’s Zenith AOI family.[1][3]
How it works
The Koh Young Zenith 2 AOI uses a proprietary light projection unit, side-view 3D camera coverage, and a digital camera with a 3D / PSMI vision algorithm. The Koh Young Zenith 2 AOI supports 3D inspection of missing parts, offset, billboarding, tombstone, coplanarity, solder joint conditions, lifted leads, bridging, and no-pops polarity.[2][1][3]
The Koh Young Zenith 2 AOI also supports 2D inspection for wrong part detection using optical character verification and polarity inspection. The Koh Young Zenith 2 AOI uses 3D inspection GUI software, Gerber conversion software, and a camera barcode reading license.[2][1]
Where it fits in the process flow
The Koh Young Zenith 2 AOI is an inline system for PCB boards and SMT production. The Koh Young Zenith 2 AOI supports real-time inspection data use in process control environments.[3]
Applications
The Koh Young Zenith 2 AOI is used for PCB board inspection in SMT assembly. The Koh Young Zenith 2 AOI is used to detect missing solder, offset, polarity, upside down parts, OCV and OCR issues, solder fillet issues, billboarding, lifted lead, lifted body, tombstone, bridging, and foreign material defects.[3]
The Koh Young Zenith 2 AOI supports inspection of tall components and obscured features through its side-view camera option and True 3D measurement approach.[3]
