Laser Decapsulation

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

BravoV:
Damn, this teases me to buy those affordable desktop laser engraving machine.  :palm:

DC1MC:
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,

MadTux:
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.
