Understanding the liquid damage

Hi!

I was wondering if someone could explain to me something.

Lets say there is a I/O board with a liquid damage (just the I/O board, no other parts), the board was working but shows tiny bit of blue corrosion in one corner, the board has been inspected, cleaned with isopropyl alcohol 99% and tiny brush several times removing all corrosion, after drying process, the board looks like brand new. Now, after the testing everything works normal, after two weeks after the cleaning process the machine has been inspected again and the corrosion didnt come back.

Now the question is, if the corrosion was tiny and has been cleaned off, and everything works fine like before for over two weeks, is it possible that the corrosion will come back later even if there is no liquid involed?

If the I/O board works fine and has been fully cleaned and dried and is connected to the logic board only by a ribbon cable and a second connector, is it possible that it will damage logic board?

Is there a need for buying brand new I/O board to replace the one that has been properly cleaned and is fully working (it was fully working before cleaning as well), if so, how sure can I be, that the new I/O board that the seller will send me doesnt come from previously liquid damaged machine and has just been fully cleaned?

Please help me understand this

Water and the ensuing corrosion can create short circuits in the board, causing links where they shouldn't be and further damaging things since electricity can now go somewhere when it's not supposed to. With water damage cleaning processes, there's always a caveat that a result of a working device is no guarantee that that device will continue to operate as intended. Generally, a thorough cleaning process takes care of the issue, but this depends on a few factors; namely, in my opinion, what we can actually see.

We can see the surface of the board just fine with our eyes and magnifying glasses or microscopes, but I suppose there is still a possibility of a very tiny amount of corrosion (or, in some cases, liquid) existing in some tiny nook or gap that is not readily visible to us.

Typically, from what I've seen with a successful cleaning, is a working device that is returned to a reliable state, but it's hard to predict or know for sure. If the effected part is inexpensive, I always recommend replacing it, especially if it's an easy repair. Hard to put a price on peace of mind, though. If we're talking about the mother/logic board, and nothing has happened for two weeks following (as in your case) with daily and normal use, then it's likely you're past the point of rolling the dice and in the clear.
