Title:

Is it good practice to soak PCBs in alcohol?

Text:

Hello all!

So I’m going to make a second attempt at repairing my Xperia X after removing the metal covers over the NAND, CPU, and some other components. I can’t see any corrosion, but I’ll clean it with alcohol just in case.

Over my experience of repairing this device, I’ve soaked the motherboard in isopropyl alcohol (90% alcohol by volume) multiple times for about 72 hours in total. I want to know if that soak can wear down the traces on the motherboard (which might be launching me into even more uh-oh). If it does wear the motherboard down, how much does it wear away? Given my current soaks, would it have worn away traces?

Thanks in advance!
