3D AOI by Koh Young
As world market and technology leader, Koh Young has over 15 years of experience and know-how in the field of 3D inspection. With extensive software tools for analyzing and monitoring the process, Koh Young systems provide more than just 3D measurement and enable targeted process optimizations. Suggestions from users are continuously incorporated into the development of the systems.
INLINE 3D AOI
Koh Young's AOI systems accurately measure components and solder joints in the third dimension and easily overcome challenges such as overshadowed components and PCB warpage.

Evaluation by height
-
Highly precise 3D inspection
- Inspection according to IPC-A-610 standard
- Shadow-free measurement through multi-way projection
- Accurate 3D measurement up to 25mm height by Multi-Frequency Moiré stripe grid projection
- 3D side cameras
- Foreign material inspection (FMI)
-
Optimal character recognition
- Integrated 2D inspection for the detection of markings
- Adjustable illumination setting via three RGB rings for optimal text and character recognition
-
Configurable Stop
- Individual definition of undesired states that trigger the configurable stop
- Automatic interlocking as soon as the defined condition occurs
- The operator is informed about the interlocking with an error message
- Examples for process interlocking: detection of serial defects, monitoring of the yield, abnormalities in critical components
-
Auto-Programming (KAP)
- Automatic teaching and adding of unknown components to the component library
- Even without the required presence of an operator
- The component library grows fully automatically
- Enables up to 70% savings in programming time.
-
Process control and optimization
- The KSMART tools turn an AOI into a tool for process control and optimization.
- The machine states of Koh Young equipment, the status of production, and much more are stored centrally on the KSMART server
- Detailed error reports can be viewed and managed
- Conclusions about the entire production, targeted interventions in the process and optimizations become possible
-
Compensation of board warpage
- Z-axis tracking for automatic compensation of PCB warpage of up to ± 5mm
- Zero referencing for each component
- Warping has no influence on the measurement result
FOR THE IDEAL 3D INSPECTION RESULT
3 TYPES OF PROJECTORS
1
Piezo-technology
With Koh Young's patented piezo technology, a solid striped grid is moved over a piezo crystal with the highest precision. This process guarantees the highest measurement accuracy
2
DLP-projectors
The DLP projectors project a digital and adaptive fringe grid that adjusts to the height of the components. In this way, components with a height of up to 25 mm are measured precisely.
3
Virtual projectors
The virtual projectors combine the inspection results of the physical projectors and enrich them with further information.
3D INSPECTION SYSTEMS FOR THE BEST PROCESS RESULT
Zenith 2
The Zenith2, a perfected further development of the Zenith, impresses with powerful side cameras for optimal defect detection and features that ensure a smooth and controlled production flow.
- camera resolution: up to 12MP, 15µm
- FoV-size: up to 56mm x 56mm
- PCB size: up to 700mm x 690mm
