Laser Decapsulation
« on: December 26, 2020, 09:22:36 am »


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

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  >:D.
Too bad that I don't speak French, it would have been interesting to understood the comments.

 Cheers,

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.

I believe it might be Russian.

This is likely a mobile phone glass back remover, not an engraving machine. About 1500$, for an eye destroying machine without an interlocked casing.

Would 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.

Your belief is correct.

I didn't even know such things were being used for that purpose - the Chinese are definitely very creative...

Something about dispelling an Internet myth that iPhone modems can be repaired (modified? - not sure) by opening them and changing components inside.

I used one of these in my previous role to recover data from damaged memory cards and chips from phones. Great fun.

No, absolutely French.  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.

I mean, maybe if you’ve never heard French before…

Because that doesn’t sound anything like French at any point.

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.
