Zenith S
The Zenith S is a True 3D measurement-based off-line automated optical inspection machine designed to maximize production quality of large, complex boards like backplane and server panels, while delivering both versatility and flexibility for cost-conscious manufacturers.

Incomparable True 3D Inspection Performance

Advanced Tall Component Inspection

Reliable Selective Solder Joint Inspection Capability

Whole-Board Foreign Material Inspection

Integrated Versatility for a Wide Range of Applications

Reciprocating Shuttle for Easy, Efficient PCB Loading

Fully Compatible with Koh Young In-line 3D AOI
Full 3D data-based process optimization solution: Realization of industry 4.0 smart factory
The new Zenith S, part of the Zenith AOI Series, is the industry’s only solution based on the IPC-610 standard for end-product acceptance criteria for consumer and high reliability printed circuit assemblies. It provides clear, precise AOI measurements to accurately identify multiple defects, and because it uses a quantitative True 3D measurement-based approach, the system delivers trustworthy accuracy and repeatability.
A True3D AOI solution, powered by AI for exceptional accuracy and repeatability
The Zenith S system is fully compatible with other Koh Young inline True 3D AOI systems. Manufacturers using the inline and standalone AOI systems like the Zenith S can prepare the job program on either machine. Additionally, operation and maintenance training is minimized thanks to the commonality between the platforms. Finally, the Zenith S uses the same central library, Offline Program Optimizer (OPO), and the AI-powered Koh Young Auto-Programming (KAP) features as the inline versions.
