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.
What is a PCB made of?
Printed Circuit Boards (PCB) are made from layers of fibreglass and copper, glued together. Whilst the glues used are very heat resistant it is possible to overheat a PCB and damage it. Kitronik PCB designs use large tracks and pads to help make this a rare problem, the larger amount of copper helps to dissipate the heat.
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.
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.
