best way I’ve found to isolate and repair water damage is to open it up and apply some high quality liquid rosin to the water damaged areas. then hit it with hot air (300c should be fine) to get the rosin under all chips and connectors. lastly, do not clean the board, it can push the corrosion around and cause more issues.

You are just trolling right?

no. if you want to do component level board repair for water damge, this is how you do it professionally. I’ve been using this strategy for 5 years or so now and it has much better success rates than just cleaning the board with ipa.
maybe overkill for most people since it requires more specialized tools but if you go to a shop they’ll most likely use similar techniques at least to assess the damage

I mean, solder melts at temperatures lower than 300 degrees Celsius.
AllHailTheSheep@sh.itjust.works 2 days ago
depends on the type of solder but yeah, I’m not exactly holding it there tho. just high airflow at that temp for a few seconds to push the rosin underneath the chips. helps a lot with bga chips where water can actually get underneath the chip and short connections or leave debris even once evaporated. for actually reworking chips I use around 480c.
