Let's say you're taking a bad component off a board and when you try to pull your desoidering ribbon up, part of the trace comes up with it. Oops! The trace isn't damaged (whew!) and you go ahead and put everything together and it works, but now you got this loose trace you're fearing.

Question: is there anyway to reattach the trace to the board? Or would I be better off just leaving it as is? It's not a huge piece of the trace, but I don't like leaving things to chance.

When I worked with board level repairs, we always cut the trace and ran a wire to replace it, Much rather have a solid connection like that then a bent loose trace.

Where I used to work we would put a little contact cement (wal-mart)
under it and push it back down. It's clear and it does a good job. Cheap fix - clear silicon but it doesn't stand up to heat well.

There is a type of nonconductive tape, I beleive it's called tapcon (?) It has an orange tint to it. If you don't want to cut the trace and wire in a replacement, I recommend pushing it down and covering it with this tape. You could use black electrical, but you can't see through it. Regular scotch tape aside from possibly conducting ESD, has the potential to melt should enough current flow through the trace.

You can buy a bottle of this ferrous epoxy stuff, which is used to repair the "traces" of rear window defrosters (in cars). Good stuff.
