What are all the necessary steps in removing corrosion from a logic bo
I was given a severely water damaged iPhone 6 that had absolutely no treatment to remove the water. I don’t think it had contact with the water for more than a few minutes, but I’m unsure of that. Unsurprisingly it showed no signs of life when I tried to power it on, and I didn’t try charging it for obvious reasons. Then I opened it, got distracted, and left it for a couple months thinking it was unfixable due to the amount of corrosion inside. Today I remembered it and decided to give fixing it a try with my 99% isopropyl alcohol. Now I’ve never done this before, so I have a few questions. I tried finding answers online, but every single thing I read said different things, so I decided my best option was just to ask on here.
From what I gathered I just need to brush the board with IPA. Is that all I have to do or do I need to do anything beforehand? Some places were saying I needed to wash it with water, is that necessary or not? It seems not right to me but what do I know. They also said I could dunk the board in IPA and not brush it, but wouldn’t the alcohol just evaporate? If I do that how long should I leave it soaking for?
The corrosion is not just on the logic board, there’s also some on the flex cables and other parts. Is it the same process for those?
Basically I want to know all the recommended steps since what I’ve been looking at is extremely confusing.
