So, i'm thinking of a story and i need some tech info.
How risky is to de-solder an usb plug if the flash-drive contains important files? It would be relatively safe for someone capable, or the heat is way too risky for the chip/content?
Also there's any (MacGyver like) way to quickly access the file or reconnect the plug without a solder while only having access to office supplies?
It's a difficult enough task that I would probably be unable to suspend disbelief.
That said, if your hero has some time and a soldering kit it would be fairly doable and relatively believable. Also keep in mind that most flash drives now have the contacts for the USB port as part of The printed circuit board that has the actual storage on it and usually the actual storage would be encased in resin, at least with a good flash drive.
The cheap ones, you could totally do this though.
