The dissimilar metals will corrode from galvanic action and cause a faulty connection that could cause a fire.
Is Gorilla Glue electrically conductive?
No, CA glues are not conductive. They're really just a polymer just like any other plastic. The bigger concern would be getting glue on the contacts that would prevent a good connection. Cyanoacrylate adhesive ("unfilled" that is without carbon oder metal particle filling) is typically not conductive.
Can you hot glue instead of solder?
No, you can't. A hot melt glue gun does not get as hot as a soldering iron, and the highest temperature is inside the chamber, not at the tip. ... It is applied in addition to solder, so solder provides the electrical connection and the glue provides some additional mechanical support.
Is solder stronger than epoxy?
Solder is stronger. JB weld is easier. JB weld is epoxy; it just has a filler that is hard, and made for cheap fixing of castings. JB will be stronger than a bad solder joint so if you cant make a solder joint for nothing, JB will be good. Oct 19, 2013
