What is the 'NPI Paradox'?

It refers to the inefficiency where the time spent programming an AOI machine exceeds the actual production runtime of the batch. In High-Mix/Low-Volume (HMLV) manufacturing, this setup bottleneck often forces operators to skip inspection entirely for prototypes, increasing the risk of shipping defective boards.

How does DaoAI SMT Visual AI differ from Traditional AOI?

Unlike pixel-matching algorithms that rely on rigid component libraries and strict template matching, DaoAI utilizes deep learning generalization. Our system "sees" components like a human expert—recognizing parts based on features rather than exact pixel values—allowing it to handle slight variations in lighting, position, or vendor branding without triggering false alarms.

Do I need a 'Golden Board'?

Not a "perfect" pre-verified standard. You simply need one physical reference board from your current batch. The AI scans this unit to auto-learn component locations and visual characteristics instantly. This eliminates the need to source a flawless "Golden Sample" before you can even begin programming.

Can it work with CAD files?

Yes. The system seamlessly imports Pick-and-Place (XY coordinates) and BOM files. By combining CAD data with the visual scan, the AI automatically maps component locations and verifies polarity, reducing the programming time from hours to minutes.
