MENTO 3D AOI On-Site Trial: Customer Asked Us to Prepare the Contract on the Spot

MENTO 3D AOI On-Site Trial Turns Into an Immediate Contract Request

During a recent on-site trial, MENTO's 3D AOI (Automated Optical Inspection) system delivered results that far exceeded every expectation. The customer had invited our team only to verify performance, yet the moment the 3D imaging appeared on screen the whole inspection area went quiet — and then broke into praise. The depth, clarity, and detail reproduction of the 3D view were on a completely different level from anything the team had seen before.

From 2D Guessing to 3D Certainty

Traditional 2D AOI leaves operators judging defects from flat, single-angle images. It works, but it relies heavily on experience and still leaves room for doubt. Moving from 2D to 3D changes the entire inspection logic: instead of an experienced guess, the operator gets a visual confirmation. Every critical solder feature is shown with real height and volume data, so what used to be ambiguous becomes unmistakable.

Solder Defects That Are Now Obvious at a Glance

With true 3D height measurement, the defects that most often slip past 2D inspection are exposed immediately:

• Solder joint height — measured and displayed instead of estimated
• Solder climbing — clearly visible in 3D profile
• Insufficient solder — detected by volume, not by shading
• Cold solder joints — distinguished from good joints with confidence
• Lifted leads — height differences reveal what flat images hide

2D vs 3D AOI: What Changes on the Line

A Reaction That Spoke for Itself

The customer reviewed the results several times, praised the system repeatedly, and then asked our team to prepare the contract on the spot. For an equipment supplier, there is no stronger proof than a decision made in the moment, on the factory floor. That outcome was not won by a sales pitch — it was won by the equipment itself.

What This Means for Our Customers

Good equipment speaks for itself. When a system genuinely solves a real inspection pain point, customers can see it instantly. The 3D AOI did not just show boards more clearly — it removed the uncertainty that slows down quality decisions and lets defects escape to the next process.

Next, our team will go all out to advance the contract, delivery, and service, turning the on-site surprise into long-term value on the production line. We thank the customer for their trust and the team for every refinement that made this result possible.

3D AOI: More Confidence in Every Quality Decision

3D AOI is not just about seeing clearly. It gives quality inspection greater confidence — measured data, confirmed defects, and a faster path from inspection to a reliable decision. For SMT and PCB manufacturers, that confidence is the difference between hoping a board is good and knowing it is.
