So, your repair works for the time being, BUT: the problem I see here is that the rivet-like plated holes (known as "vias") that pass voltage or signal through the board from one side to the other are visibly corroded, especially down inside where you cant see it, and eventually they will fail. Sometimes you can clean the face of the via on either side of the board and pass a very thin jumper wire down through the hole and solder it on both sides, but it's tricky, and sometimes the hole is too small or full of corrosion, or a varnish-like conformal coating from initial manufacture, to allow a wire to pass through the hole. I repaired a Bose radio once that had some kitchen spillage in it; the cortosion was confined to about a 1 square inch area on the double-sided board, and yet it turned out to be much more work to fix it than I had expected. PS, Don't use an exacto knife for scraping the corrosion off of the board, use a fiberglass-bristle "scratch brush"; you can see them in a video on my channel. An ink eraser is also helpful if it has pumice or silica or other fine grit embedded in the rubber.

Thanks for sharing your experience. I'll be on the lookout for that issue.
Ah I didn't know I was giving spoilers in the last video. I didn't know about the nail polish trick! That's a great idea!
Thanks!
Interesting tks for sharing
You're welcome!
Thanks for the update and details 👍😎👍
You're welcome!
You can get solder mask for not much more than nail polish. You can also instantly cure solder mask and nail polish with U light.
Thanks for the info!
I do have a circuit board that was torn and I am not that expert with fixing circuit board is there a way to fix it? Thank you!
I’ll have to remember that fingernail polish trick.
Thanks Chris!
Great
Tnx !
You're welcome!
how should I clean corrosion from bleach?
Just get isopropyl alcohol
👍
Thanks Troy!
No it wasn’t wtf
