I recently got two SE/30s. One had a battery bombed motherboard which had pretty bad corrosion and is out of repair in my opinion. The other motherboard was not touched by corrosion but was showing the Simasimac issue.
I am not an expert at soldering but I did a couple of successful recapping on LCs so I decided I would recap the second motherboard.
While soldering C7, I put too much flux and had some of it going under the ASC chip. I tried to remove with some 95% ethyl alcohol (as I don't have IPA) and a toothbrush. I also made sure that there was no short between pins.
When I tested the board, there was no more Simasimac pattern but the chime was pitched up and it hanged on the grey screen. I though it was due to the mess I made with the ASC chip, so I tried to clean with more alcohol, even by blowing some compressed air around that area to try removing as much residue as possible, but the more I cleaned, the worse the chime was until there is no chime anymore and the mac still remains on its sharp and consistent grey screen.
Maybe there is another issue with that board but I would like to clean that chip first in order to make sure that it is not the cause if the problem.
I don't have an ultrasonic cleaner so I was wondering what was there was another way to clean up my board.
Here is a picture of that particular area after recapping.
Thanks for your help!
