content: Interesting how the package seems to just evaporate away, leaving behind the die and bond wires.

content: Lovely how the flash dies were stacked on top of each other, I'm wondering if some content remains in the flash or if the logic blocks survives the decapping, if so, is indeed very interesting for a lot of data recovery and nefarious purposes.Too bad that I don't speak French, it would have been interesting to understood the comments.Cheers,DC1MC

content: Flash should survive just fine, I guess.Laser is likely Nd:YAG with 1064 nm wavelength, so not enough photon energy to erase the Flash, just as you can leave an EPROM in the sunlight for weeks without erasing it.This and some reflected light microscope with nitrogen laser mounted to it might be a nice setup to erase lock bits.

content: Quote from: Marco on December 26, 2020, 03:20:11 pmWould have guessed a much higher price for such a machine. Eye destroying only if you look at it while doing it's thing without laser glasses. Add another 50$ for laser glasses and some plywood to build a box for it and you're likely fine.

He was speaking a bit too fast for me to follow, but I recognized enough words to ID the language.WHOOPS, first part REALLY sounds like French, then a minute later it starts sounding quite Russian! And, the datasheet is clearly Cyrillic.Jon

content: This is 100% Russian!!There was never any French in that clip. Don't know how people heard that...For those who wanna know what they are saying:click the cog (settings) --> Subtitles/CC --> choose the only language --> "Russian (Auto-generated)" --> Click the "Russian (Auto-generated)", and you can now "Auto translate" to your preferred language.
