Repairing fine pcb traces

[Sanxion]

Hi all,

I would like to ask if it possible to repair very fine pcb traces that have become corroded. I have an old computer board that has suffered from a battery leak. Please have a look at the image and let me know if it possible and if so, how.

Thanks.

i take in a multibraid cable  one of the small wire in them,   you can choose the core wire size ...     or wire wrap   etc .....

scrape the pcb varnish on each pcb trace and carefully redo them     but dont overheat,   they could lift from the pcb

it will be a long  process  if you are able to do it


But   the way i see it  you have  corrosion in the white plug  ....   many places have been damaged,  not sure i would do this amount of work   

you can or could find another pcb ??  unless it is a special board ?

and in the end  you may still get some failures over time ......

Top left corner doesn't look good too!

I'd say don't waste your time, unless it's some super-rare board that is of historical importance and irreplaceable.
There has been so much corrosion done to the board that you would need to replace every single trace and most parts - and you can only see the damages on the top layer. The further down layers are likely damaged in the same way and are unreachable.
Unfortunately, the corrosion will never stop and will worsen over time, so a "good" trace might be eaten away in a year or two or three. Essentially a ticking time bomb.

I knew it was bad but thought I would give it a try...I did actually fix a few traces and restored some functionality but it probably is too far damaged. Thanks for all the responses!
