PS3 Broken BGA pads/traces on RSX side, how to fix them?

So i have a questions i've been meaning to ask since i start doing reballing. It happens that sometimes (mostly on ps3 fat consoles) pads get ripped either during chip lift or while cleaning the area to prepare for reballing. Some pads are connected as i saw on schematics but some are ground. I had luck with recent reballing where i ripped 2 pads but they were ground, and console is still working since i reballed it.

My question is: as some pads are not connected and have no traces, how do we fix them? I will post pictures below to show example.

As you can see on pictures, that pad is CLK1 OUT. Where should the wire connect in order to fix that pad? I'm still new to reballing and other stuff but i would like to learn as much as possible, so if anyone can help me and other who have those issues, please and thank you in advance.

forget about them, leave them as a donor consoles and get mobos with dead chips to transplant nor + cpu + syscon and have a working console

how are you reworking? with an actual BGA machine?

That's why i got into fixing stuff in a first place. To fix as many YLOD consoles as i can. I hate to see consoles that could be repaired just die out there instead of finding it a new home and learning something in a process. People in my country cast aside YLOD PS3's, hell they cast aside PS4's with BLOD. They don't want to bother with it and there are almost not reballing services. But i want, i want to fix every pad, if it's possible, every component (i know it sounds dumb and of course i know some consoles can't be fixed because they were dropped or have warped boards) but i just hate seeing them as paper weight instead of playing call of duty on them.

I have honton R490 and this machine is something best that ever happened to me. I had a lot of trouble getting one (hence why so few people in my country actually do reballing) but i have managed to fix a few consoles with it (i have used it only couple of times and still learning profiles and temps) and i will share with this community as much as i can while working with it.

You can try spraying it with IPA, you should see where the trace ends, it will be the size of a dot, you will need to scrape off the resin of the board, solder a tiny copper wire and roll it into the shape of the pad and cure it with UV glue, this is extremely difficult to solder and extremely challenging, good luck.
I found a video you can watch starting at 5 minutes in, hopefully this will be allowed on the RSX as well.

@NightLess Thank you, every bit helps. I have electronic microscope and i have encountered broken traces before, but they mostly had lines which could be traced to source and repaired. I will investigate further
