Re: Is it possible bridging tiny broken trace

That's quite a few traces there.
You'll need to remove the solder mask in that area so you have clean copper to solder to and to get a better look at the damage. There are cheap grinding pens available, they are better than scraping at the board with something sharp. https://www.aliexpress.com/item/1005004662172521.html

You want to flux the area then tin the traces with solder, then use either fine wire or the PCB trace repair kits. https://www.aliexpress.com/item/1005003152519345.html

Then solder mask on top when you know it's good.

When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
cutting tiny trace.
This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.


Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.

But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging tiny broken trace.
And I have been using burnley solder paste for soldering But I think that Now I need a lot better solder paste or flux for this delicate soldering of bridging tiny broken trace.
Is it possible to bridging tiny broken trace like above screenshot and
If It is really possible to bridging tiny broken trace, What diameter size of coper wire and what type of solder paste or flux do I need?
