Tip for pcb board

[urbanflyman]

I did some soldering to repair a watch recently.
The tiny tracks lost continuity,apply a mini tipped silver conductive pen,prior to soldering! this helps the solder take to it!

Hi.
What solder gun or tool did you use to make the repairs on the board.?

Just a fine tip mains voltage solder iron!
I tested the tracks first! found where continuity stopped! then scraped back some track insulation!
Next step? apply the silver conductive pen! then solder over that after! worked a treat! I had four track faults on one watch!
