Scrape a little of the solder resist off with a knife, sharp screwdriver or fine sandpaper. Ensure that the exposed track is clean and shiny. It is also a good idea to clean any residual burnt PCB material off, to allow the tape to stick well.
What happens if a PCB is overheated?
If a PCB is overheated the most likely outcome is that the copper layer will de-laminate from the fibreglass board. This usually leads to broken joints and a non-working circuit. It is possible to repair some faults using adhesive copper tape and solder. Ask Question.
Can copper tape be cut?
The Copper tape can be cut to size with scissors, craft knife etc. Once a repair has been made it is also possible to trim the excess tape. If this is done exercise caution, as the repair is more fragile than the original PCB track, and may become unstuck again.
Can you overheat a PCB?

Does copper tape melt?
Carefully solder the joint (s) where the repair has taken place. Most copper tape adhesive melts at soldering temperatures, so be quick and use as little heat as possible. When the tape cools the adhesive will usually remain sticky.
Why is my circuit board failing?
Aside from physical damage, faulty components are the other most common cause of printed circuit board failures. In fact, if and when there is no physical damage but a device has failed to operate or power on, you can almost guarantee it has to do with one of the components connected to the board.
What causes PCB failure?
