To live or not to live

Question

USB flash drives

Hello!

I disassembled the USB flash drive - in front of me is a board with schematics and a USB connector. I plan to fix this scarf inside the metal case to keep it)

There are three mounting options, or rather two - I don’t want epoxy. There remains molten polyethylene (from the “gun”) and paraffin (yes, even from a candle). Paraffin melts at ~ 70 * C - it is easy to “drop” it and, if necessary, it will be easier to disassemble. Polyethylene is also convenient, it holds much better, but the downside is that the temperature at the time of installation will be ~ 160-200 degrees (and this is 20 seconds).

I want to use liquid polyethylene, respectively, my question is simple: will the flash drive remain alive after such a heat stroke? :)

Answer 1

All components of the flash drive (except perhaps the LED) are designed for soldering in an oven. A typical soldering profile ( for example ) will heat up to 235-250 degrees for 45-90 seconds. So nothing should fall off. Just in case, pour in several steps, allowing to cool.
What's wrong with epoxy?

Answer 2

Silicone sealant will not heat up at all :)

Answer 3

Protest first on a cheap gig flash drive (probably lying around somewhere at home)

Answer 4

If you keep at the same time, everything will be strong - I am for paraffin, because under normal conditions you are unlikely to heat the flash drive to 70 degrees, even running with it in the back pocket of winter jeans at the stadium under the July sun.

Answer 5

200 degrees and even 20 seconds is a lot. The components themselves will most likely survive, but this is already the melting point of solders. Something might fall off.

Answer 6

Everything will work. I checked this myself when I made an unsinkable flash drive for myself.

Answer 7

will work. my colleague made a so-so case for a flash drive) filled everything from all sides with a glue gun - it turned out funny and unique)
