Ultimate Solution for Inspection Challenges

Circuit boards are becoming more complex with new products. An AOI machine is becoming even more crucial to electronics manufacturing lines. The industry has many 2D, 2.5D and pseudo-3D inspection options that only compound issues with false calls and escapes. The Zenith AOI series is the only machine that delivers True 3D inspection to address solutions caused by highly specular packages and shadows from adjacent parts.

Incomparable True 3D Inspection Performance

The Zenith AOI Series is the only solution in the industry to base its inspection criteria according to IPC-610 standards for electronic assembly acceptability requirements. It provides clear and precise AOI measurements to accurately identify multiple defects. Because it uses a quantitative True 3D measurement-based approach, the system delivers exceptional accuracy and repeatability.

Total IPC-610 Compliance Solution

By importing PCB Gerber Data, Koh Young 3D AOI system can measure all aspects of the component and solder joint in accordance with the IPC-A-610 standard. This eliminates the need for a golden board and time-consuming manual program set-up.

Library thresholds are defined as IPC-A-610 parameters, allowing the use to choose class I, II, or III.

Full 3D Coverage with Powerful Side-View Camera

The flagship AOI model, Zenith 2, combines Koh Young’s advanced vision algorithms with innovative technological advancements of “3D side-view cameras” to expand the inspection coverage. The new cameras further enhance the defect identification capabilities across a wide range of components, including leadless chips, connectors, SOJs, QFNs, and partially shielded components. With this innovative solution, Koh Young’s latest 3D AOI system is advancing towards unprecedented quality by improving defect identification and increasing quality control.

AI-powered Auto-Programming (KAP)

Industry-leading 3D profilometry technology converges with Koh Young’s proprietary AI technology to deliver true automatic programming. The innovative geometry-based Koh Young Auto-Programming (KAP) software solution reduces the programming process to minimize production preparation time and reduces costs.

Self-Diagnosis for Optimal Performance Maintenance

Koh Young’s self-diagnosis allows operators to take precautionary measures through predictive maintenance to reduce process interruptions, enhance equipment uptime, and ensure optimal machine performance. This feature has distinct modules that offer periodical machine checkups on critical items such as 3D/2D light intensity, PZT feed, height accuracy, and XY offset.

KSMART Solutions: True 3D Measurement-based Process Control system

Koh Young is pioneered True 3D measurement technology 20 years ago to zero-defect future. This gave rise to KSMART Solutions and its continuous efforts to leverage data and connectivity.

KSMART Solutions uses Artificial Intelligence to help automate process control while focusing on data management, analysis, and optimization. It collects data from across the factory line for defect detection, real-time optimization, enhanced decisions, and traceability to improve metrics, increase quality, and lower costs by eliminating variance, false calls and escapes.

Zero-defect through AI-Powered Koh Young Process Optimizer (KPO)

Based on Koh Young’s accurate 3D measurement data and its proprietary deep learning technology, Koh Young Process Optimizer (KPO) enables mounting process optimization in real-time. It autonomously identifies the heads, nozzles, feeders, reels, or components that potentially cause defects and feedback the most contributing mounting parameters to fix the fundamental problems in real-time. Based on AI-based analysis, KPO Mounter provides users actionable insights and helps enhance production quality and maximize productivity.

Fully Automated In-line Inspection Solution for
Extra-long Applications


Evolving applications like LED lighting, electronic vehicles (EVs), communications, and even storage can challenge manufacturers, especially in terms of board length.  The new USX series allows manufacturers to efficiently inspect boards up to 1,300mm long in a single pass and can be optionally configured to handle boards up to 1,800mm long.
