>>2929455 (OP)Some of the traces look pretty fucked. There is several ways going about that. None of them is pretty. A PCB starts with a solid face of copper cladding and the spaces between traces are etched away. Putting copper back will be a hack but we can do that.
To start with: Try cleaning it up and show us what we're working it. You don't need to be super gentle. Scrubbing with a dishes brush for example is just fine. Anything that comes off had no electricam continuity anymore anyways. If anything comes of thats not just flakes but actual components take note which came off where. Clean it and show us.
>>2929485>Pay someone to do itI have a general opinuon that some people have affinity to handywork and some do not. OP posting here leads me to believe OP is part of the first group. IMO it doesn't matter too much if all OP ever did was plumbing and carpentry. If OP is part of the first group OP will have a general understanding and find his was into this project.
>Toolsfunny enough manufacturing is so cheap now that you could literally buy new tools for every job. OP can get a cheap reqork station for less than the phone guy wants for an hour.
