Cyanoacrylate glue is sometimes used but is not the best

What are some advantages of cyanoacrylates?

It is easy to apply
Hardens quickly

Available on most manufacturing floors
Makes an OK wire strain relief

What are some of the problems with cyanoacrylates?

Not made to take solder temperatures
Tends to “evaporate” at solder temp and will burn away with repeated runs resulting in increasing temperature readings with each use
Is a good insulator, so if too thick, will suppress the temperature value.
