It's funny, back in an earlier job, I'd keep a board plugged into a programmer, which in turn was plugged into a USB port on my laptop. Whenever I left the restroom, my hands would be slightly wet, and touching the laptop would give me a small shock. Somehow, this shock would reset the board every time, even through the indirect connection.
I'm surprised that nothing ever actually got fried in that job. (Except for a company laptop that mysteriously bricked itself after I tried rebooting it.)
- the-grump 1y agoThat's actually fine because you were probably going straight to ground. When things are properly grounded and the small components are covered, the current will flow through the thick ground conduit (the laptop body, thick copper on the PCB, eventually into the power cable). What you'd like to avoid is releasing that static charge through a tiny component on the board that couldn't handle the surge.
