There's an electronics assembly joint near us that's going out of business, so we poached three employees and a bunch of equipment. I've always wanted a high-res xray, and I got one and the guy to run it. https://www.dropbox.com/scl/fo/lfdot6a64pg05z2x1ejo1/h?rlkey=p8lmnoy9388d3v20qv5a8qgwf&dl=0 We also got a 3D AOI board inspection machine which makes equally cool images.

Those pictures of the DCDC converter looks like some chinese thrown together and potted to look nice. Is that right? A big firm in Denmark went bankrupt, so I bought a lot of HP gear, 3 VNAs, 1 EMC test receiver, a 4GHz signal generator, a microscope, .... all for 6000 USD. Only one of them doesn't work

How long does it take it to scan things, say that PLCC 20 part? Resolution looks impressive. Can you post a photo of the entire thing?

Do you want to see the PLCC in a full-field view? Or the whole board? I'll ask Garvin to do that. The double wire bonds are interesting.

It counts parts on reels but doesn't have the resolution to see what's inside parts.

I remembered that it was a CsI screen and an area photo sensor, but much has changed since I last thought about this, so I did some digging.>Dentists are using video imagers and not film any more. I wonder how >that sensor works.From Dentron, a Dental X-Ray Sensor manufacturer: "The Dentron Direct USB sensor offers rounded corners, smooth edges, and two sizes (size #1 for children | size #2 for adults) to optimize patient comfort while receiving a dental X-Ray. The thin, tough, and durable polyamide housing is less than 1/4" and features a CMOS imaging sensor chip, CSI Scintillator, electronic circuits, shielding foils, and polyurethane cable and shock absorbers." They cost about $4K. The core patents are (or are referenced by) U.S. Pat. No. 4,160,997 to Robert Schwartz and U.S. Pat. No. 5,434,418 to David Schick. Google Patents will provide the patent pdfs.
