> more feasible than acquiring 100x die scans of the chip
Last time I had to get SEM micrographs in resolutions between 2K and 10K, we paid 475€ for 2 hours of work.
While I wouldn't want to pay this out of my pocket and gift it to the world, I don't see how it's less feasible to make better die scans than to build the testing equipment (PPU breakoutboard) needed for automated testing.
Especially if the current owner of the already decapped dies were willing to lend them to someone else willing to do the footwork.
I think it should be easy enough to find 19 people willing to donate 25€ for this kinda effort.
On the other hand, the dies would have to be plasma coated with Gold/Platinum, which might be bad, I'm not an expert. So, perhaps you were refering to this when you said higher-res scans are less feasable than making automatic testing happen. ¯\_(ツ)_/¯
