Hey guys I picked up a Star Trek last week that is working but has some alkaline damage to the MPU. I want to nip it in the bud but I haven't tackled a board with corrosion before so I could use some hand holding. It looks like it's not bad, pretty much just the outer ground traces on both sides and one socket. I don't have a bead blaster on hand so I was going to wire brush it and vinegar bath it.
My question is should I just cut, remove, and replace that bottom ground trace? It looks like it's pretty questionable anyway, I'm wondering if cutting above any visible corrosion would stop future corrosion from propagating northward? I'm reading that even neutralizing the stuff won't stop it from corroding in the future.
Also, it appears R114 has been cut. Is this some kind of mod or a hack?
Typing this on my PC and will add pics from my phone.
Thanks

I'm learning on a bad one now. You can make that look nice. I'm not much help with advice since I'm still learning. I did the vinegar bath a couple of times. Once when I first cut the battery off and knocked off the heavy corrosion with sand paper. Then again once I removed everything from the board, sanded, then gave it a vinegar bath again, using baking soda and water after each vinegar bath. The red scotch brite type pads from home depot paint section work great as a way to get the corrosion off. I doubt I got all of mine out, it was really bad, it had crept the whole way around the board.
