What To Avoid
Outdated Optical Technology
Many manufacturers make the mistake of selecting AOI systems with older-generation optical engines that rely solely on 2D imaging.
These systems often struggle with modern manufacturing challenges:
Limited ability to detect coplanarity issues
High false call rates on reflective surfaces
Inadequate resolution for fine-pitch components
Poor performance with tall components
Inability to measure solder joint volume
Oversized Systems for Current Needs
A common and costly mistake is purchasing AOI systems with capabilities far beyond current production requirements.
While future-proofing is important, oversized systems often result in:
Unnecessarily high initial investment
Increased training requirements
Underutilized features
Higher maintenance costs
Extended setup times
This is particularly true for manufacturers who could achieve their quality goals by upgrading existing inspection hardware with advanced software solutions.
Insufficient Support Infrastructure
Some manufacturers focus solely on system specifications while overlooking critical support requirements:
Can AI AOI systems completely eliminate the need for human inspection?
While AI AOI systems significantly reduce human intervention, they cannot completely eliminate the need for human oversight. Human operators remain essential for verifying complex defects, training AI models on new defect types, and making final decisions on borderline cases.
What impact does board warpage have on AOI inspection accuracy?
Board warpage can significantly affect inspection accuracy, but modern AOI systems incorporate automatic compensation features.
Systems like the TRI TR77000 and Koh Young Zenith use dynamic height adjustment and multiple reference points to maintain measurement accuracy even with warped boards. However, severe warpage beyond system specifications may still require additional handling solutions.
How do AOI systems handle conformal-coated boards?
AOI inspection should generally occur before conformal coating application, as the coating can mask defects and affect measurement accuracy.
For post-coating inspection, specialized systems with specific illumination techniques and programming parameters are required. Standard AOI systems typically struggle with the reflective and transparent nature of conformal coatings.
Conclusion
The latest AOI systems showcase significant technological advances: Saki 3Di Series excels with multi-technology inspection capabilities across SMT and THT, TRI TR7700’s adaptive height resolution technology maintains precision at 80 cm²/sec, Koh Young’s Zenith handles components up to 25mm tall without shadowing issues, and Mirtec MV-6’s Blue DLP technology enables noise-free 3D measurements on reflective surfaces.
Yet manufacturers still face persistent challenges: substantial hardware investments, programming complexity, and extended integration periods.
Averroes.ai addresses these challenges by transforming existing inspection hardware into AI-powered systems. Our solution delivers 97% accuracy without new equipment purchases or complex programming while automatically adapting to new defect types.
