So I accidentally put an open water bottle in my bag while my tablet was in there, LCD was unfortunately flooded, but I ordered a replacement screen and it arrived today. Though opening up the tablet I found water droplets throughout, so I removed every part meticulously to put in rice or something and noted any current corrosion I had to remove with a q tip.
My question is this. As soon as I opened it up I noticed the water very quickly evaporating. I actually can't see any more now. Anyone who does mobile device repairs, what do you think? Could I skip the deep-dry? I looked at all the components and none of them have any parts that could have trapped water that I missed and I don't really look forward to cleaning the entire thing of starch ( though I do just have silica beads but let's stay on topic)
Am I right to feel confident about the dryness of the components? Let me know!
You’ve already got answers about rice so I won’t comment on that.
Once you’ve noted the corroded places, clean it by using 99% isopropyl alcohol and an ESD brush. In lieu of an ESD brush, a regular toothbrush is usually fine but best practice is to adhere to ESD protocols.
The main area you won’t be able to get to is the BGA underneath some of the ICs. To clean under there, the board would need to be put through an ultrasonic cleaner.
I usually give any wet board 24 hours to dry with a fan circulating air over it, flipping the board around the 12 hour mark. Humidity is usually 30-60% where I live.
