Visual inspection for semiconductor equipment parts

Fab customers reject parts for marks and contamination that look small to the rest of the world. VZSOR is a bench camera that gives the same look to every part and keeps a photo of each one. Some part shapes, like tubes and welds, may not suit a fixed camera.

What hurts today
  • Customers reject parts for cosmetic marks and contamination that other industries would pass.
  • Weld cosmetics are judged by eye, and the call can shift between inspectors and between shifts.
  • A cleanroom customer may want proof of what was checked on a part you shipped months ago.
  • Particles and residue are hard to see under ordinary shop light.
  • Tubes, weldments and complex shapes are awkward to present to a camera.
  • Parts are low volume and high value, so one rejected lot hurts.

Strict about looks

Semiconductor equipment is built to sit in clean, controlled places. A scratch, a smear or a weld that looks rough can be enough for a customer to send a part back, even when it would work fine. Cosmetic standards here are tight, and they are often set by what a person sees.

That puts weight on the inspector. Two good people can look at the same weld and disagree. The same person can look at the same part differently at the start and end of a shift. A fixed camera under fixed light brings the look closer to the same every time.

A record of what shipped

VZSOR stores a photo and heatmap for each inspection, with the result, operator, lot and serial, and time. You can export it all to CSV. If a customer comes back with a question about a part, you can show the image taken before it left.

That is an image archive, not a cleanliness measurement. VZSOR does not count particles or test for residue. It shows how a part looked to the camera under steady light. It can help you explain what was checked. It cannot prove a part is clean.

Where a fixed camera struggles

Tubes, welded joints and parts with curved or deep features are hard to light and hard to hold in one position. A weld seam may need several angles to judge. A fixed camera with a single view may miss the side that matters.

We say this up front because it is true. Before a pilot, we would want to see the part and talk about how it sits under the camera. If it does not suit the station, we will say so rather than take your fee.

What is proven so far

VZSOR is pre-pilot. It has been validated on one part, a 2 inch by 2 inch aluminum L-bracket with a mill finish, for dents, scratches and nicks on visible faces. It is trained on good parts only, and it flags suspect parts for a person. It is not final quality sign-off.

We have not validated it on weld cosmetics, on contamination, on anodized or coated surfaces, or on the stainless and specialty alloys common in this field. A setting can keep part photos on the station, but the pilot is what shows whether it works on your part.

Good fit, poor fit

Good fit

  • Machined plates, blocks and brackets with flat visible faces where marks cause rejects
  • Parts a fab customer inspects for cosmetic condition on arrival
  • Shops that want a photo archive of each part before shipping
  • Plain metal finishes that can be lit evenly in an enclosed box

Poor fit

  • Tubes and weldments that need several angles to judge
  • Measuring particles, residue or cleanliness
  • Anodized, coated or highly polished surfaces, which are not yet validated
  • Large chamber parts that exceed the field of view

Limits, stated plainly

  • Validated on one part only: a 2 inch by 2 inch mill-finish aluminum L-bracket.
  • Weld cosmetics and contamination are not yet validated.
  • Tube and weld geometry may not suit a fixed camera.
  • It does not measure particles or cleanliness, and it does not measure dimensions.
  • Field of view is about 100 to 120 mm. It flags parts for a person and is not final quality sign-off.

Questions

Can it check weld cosmetics?
We have not validated that. Weld seams on tubes and joints are hard to light and may need several views, which a fixed camera does not give. If your weld sits on a flat enough part, a pilot could test it. Send us the part first.
Does it detect contamination or particles?
Not as a measurement. VZSOR is trained to spot visual differences from good parts, and it has been validated on dents, scratches and nicks only. It does not count particles or test cleanliness. Contamination is untested and should be treated as unproven.
Do part photos leave my shop?
Not if you turn on the photos stay on station setting. The camera and AI run on the station, and only counts and dollar figures reach the cloud. Each record keeps a photo, heatmap, result, operator, lot and serial. Check your own customer rules first.
What if my part does not suit a fixed camera?
We will tell you before you pay. Share the part or its drawing and how it sits under a camera. If it needs many angles or deep views, the station is the wrong tool and we would rather say that than run a pilot that cannot work.

Try it on your parts.
