Equipped with an AI algorithm that automatically learns defect patterns, it reduces the false positive rate by 40% compared to traditional equipment.
It supports Windows user interface operation, is compatible with various PCB board sizes, and is suitable for SMT production lines.
Performance Parameters
Measurement range: 510×510mm, inspection height: 25mm.
Fully automated design supports integration with factory intelligent management systems.
Strong vibration resistance and excellent mechanical rigidity make it suitable for inspecting high-density substrates.
Application Scenarios
It is primarily used for detecting component placement defects after PCBA assembly, such as offset, missing components, and abnormal solder joints. Widely used in semiconductor packaging, automotive electronics, communication equipment and other fields.
Koh Young's Zenith 3D AOI, a high-end optical inspection system, has demonstrated its success in the following areas and demonstrates its technological advantages:
Semiconductor Packaging and High-Density PCB Inspection
In the semiconductor packaging field, the Zenith 3D AOI utilizes True 3D technology to achieve shadow-free inspection with an accuracy of ±10μm, effectively identifying solder joint defects on complex components such as BGAs and QFNs.
A high-density PCB manufacturer has seen a 40% increase in inspection efficiency and a 30% reduction in false positives after adopting this system.
Automotive Electronics and Communications Equipment
Automotive electronics manufacturers are leveraging its AI-driven defect learning capabilities to optimize zero-defect processes, particularly for automotive-grade products with stringent reliability requirements.
Communications equipment manufacturers are leveraging the simultaneous multi-processing feature to rapidly switch between inspections of multiple PCB models, shortening production cycles.
Cost Reduction and Efficiency Improvement Case for Small and Medium-Sized Enterprises
A Shenzhen SMT patch factory increased its inspection efficiency by 40% and reduced labor costs by 60% within three months by leasing used Zenith 3D AOI equipment. The lease offers flexible return after the peak season.
Wenzhan Electronics' refurbished equipment solutions enable small and medium-sized enterprises to achieve near-new performance at 30%-50% of the cost.
Technical Verification and Industry Recognition
The equipment's vibration resistance and mechanical rigidity have been verified in industrial environments, making it suitable for high-vibration production lines.
In the 2025 AOI Equipment Recommendations, Koh Young was listed as a benchmark brand for 3D inspection technology.
