Can someone who knows shit about electronics answer something I've been thinking for awhile?
We all know water's bad for electronics but if I take a component such as pic related that's not hooked up to any power supply and soak it in water, would it work afterwards as long as it is completely dried out? Why does getting a non-powered electrical component wet matter if it can be dried out?

Impurities in the water are the main concern, otherwise there's no reason it wouldn't work after being completely dried.

mineral deposits in the water left on the board can short it out once its powered again

try to avoid dropping your computer in pools pls

Perfectly pure water would be fine, but perfectly pure water is impossible to work with because everything loves to dissolve in water. Trace elements would dissolve from the computer tower itself and then you'd be screwed again.
(And also, obviously, "a pool" as in a swimming pool is not remotely pure water.)

You're an idiot.
You can clearly wash electronics. In fact most of them are washed upon leaving the assembly line.
You can do with with regular water but they should be rinsed with either distilled or some isopropilic alcohol later.
Better washed them with distilled water from the get go.
And thoroughly dry them.

Can't confirm, but I've read that using mineral water is safe.

>Better washed them with distilled water from the get go.
Distilled water is expensive. It might be cheaper to wash them thoroughly with normal water and then clean them shortly with distilled water.

Nigger go work in a factory.
You don't wash used electronics, the capacitors on the PCB will meet the now-salinated water you dipped them in and push some mamps through circuits they are not designed to go through.
Yeah a factory producing PCBs might spray them with febreeze for maximum added-value, but an unemployed beardo with a malfunctioning PCB will not do well rinsining off his computers motherboard under the fucking bathroom sink.
Shame on you, asshole. Shame!

That only applies for ordinary tap water which has minerals and plenty of ionic impurities in. The ionic impurities allow an electrical current to flow and that's why submersing electronics in water is a fucking stupid idea. As for drying out? Trace amounts of minerals can be left on circuit pathways, so cleaning with isopropyl alcohol or even de-ionized water will be necessary.

I worked in a repair shop and some of our devices pcbs get covered with gunk.
We scrub them with isopropyl alcohol and nice cotton pads that don't leave fibers

Hard drive would be fucked.

If it's 100% pure water, no impurities whatsoever, then when all the water evaporates it should be fine. It's the impurities that are conductive, and that's what kills electronics when they get wet.
Somewhat related question:
Does 100% pure water conduct electricity?
my house flooded once and my entire computer was underwater for a few hours. it never turned off.. could move the mouse and everything. case wasnt water tight either.
wound up rinsing it with rubbing alcohol. had no problems at all.
it was surprising to say the least.

Why didn't you turn the power off at the fusebox/utility panel (or whatever it is called)?
>>7931313
Yes. Not much, but it does.
