![]() ![]() ![]() Oxygen and humidity can generally still get into the joint, and these are what eventually will degrade the connection. If you have two wires that are well twisted together, covering the joint with heat shrink tubing or tape can insulate the otherwise bare metal and prevent shorts (essentially the same job as a 'wire nut'), but has no other advantage. ![]() For instance if I have soldered wires coming off a pcb i'll plop hot-glue or epoxy over the connection to glue the wire to the PCB and remove stress from the solder connection.Īdhesives aren't going to provide any electrical conductivity, and aren't likely to work well with metal surfaces since these don't tend to be very porous. I do use some of them as insulators though. I would never use any of these in place of solder. (Thanks Michael/Jeanne)ĭuct tape's core is a conductor, but the coating and glue on the tape is an insulator. its not doing the job of solder though, its not providing the electrical connection but rather just keeping it from coming unwrapped.Įvery type of epoxy i've used has been an insulator although there appear to be some that are conductive and may be useful in specific situations. i have heard of people using it to provide extra hold on wire wrap boards. Super glue (cyanoacrylate glue) is a good insulator. Hot-air-gunning, do you mean hot air soldering or maybe given the nature of the other things mentioned heat shrink tubing? Nothing you listed is a substitute for soldering, they are all things you can use for physical attachment or insulating but are not things to use for making an electrically conductive connection. ![]()
