user80068: Like subject all ready telling you, I blew up my 3th Nano every.
I mounted them on a perf board, soldered with 99% tin 1.0mm and a Flux, cleaned with flux remover, etc... When I then power them up through USB I have a short on pin 29 and 30 (Vin Gnd). And the board is ready to go directly in the poubelle (the garbage thing).
Second and third time, after soldering I scratched the space between both pins to make sure there is no connection. But...
Yip again. Is this a common issue? Am I overseeing something?
Did my measurements with multimeter. No shorts.





user80145: If i am not wrong you have soldered nano directly to the  perf board, which i don't recommend at all. You could try soldering a female strip pin on to the pref board and insert the nano board in the strip pin. This way you could easily remove/install the board easily as you wish.
