Non-conductive-removeable-glue ?
Hello,
I have a question for you: Is there a glue that can be used to glue together electronics without the glue becoming conductive after a while ? (Some glue's appear to become conductive after exposure to heat, moisture in air, and electricity (?)) Also it would be a big plus if the glue can be removed with water and soap or any other means... Bye, Skybuck. |

Going to try and forward this to chemistry newsgroup.
(Failed, no such newsgroup, so just gonna be a regular follow-up:) Electrolysis comes to mind... I learned that once in a chemistry class on school. http://www.thefreedictionary.com/electrolysis From that dictionary: " 1. Chemical change, especially decomposition, produced in an electrolyte by an electric current. " The thruth could be that no glue is safe from electrolysis ? Bye, Skybuck.

Some further slightly interesting links:
Electrolyte: http://en.wikipedia.org/wiki/Electrolyte Glue: (Doesn't contain much about non-conductive glue) http://en.wikipedia.org/wiki/Adhesive Maybe glueing electronics together is a bad idea and simply indicates non-sturdy/bad design (?!) One more link: printing electronics: http://en.wikipedia.org/wiki/Printed_electronics One possibly solution for the future could be a "double board" where components are stuck together at the bottom and the top for extra sturdyness ?!? Ofcourse this would make inspecting any damage impossible until everything soldered loose... hmmm ;) :) Bye, Skybuck. "Skybuck Flying" wrote in message b.home.nl...

I had to fix one or two Sansui amplifier power boards with that conductive stuff. I have used typical hot melt without problems, but usually not on a conductor. I also use silicone rtv on most things. Anything removed with soap and water seems like it would collect moisture anyway. greg |

(Failed, no such newsgroup, so just gonna be a regular follow-up:) Try sci.chem (which seems to be on an anti-semitic binge right now, but there are real chemists there). The answer you seek is that some glues interact with electronics. The acid in silicone, especially, will dissolve traces on circuit boards. Other than that, it works fine, especially if you apply it in an area without traces. Don't trust a solder mask; some are porous. Most other glues are nonconductive, too, such as epoxies. You can make them conductive with metal particles, but the native glue is conductive. Dangerous Bill |

It's the only glue that works reliably with Teflon, too. Dangerous Bill |

This could be the reason why the repairman said that nothing could be done about the "glue". (He hadn't seen it though... just over the phone...) So the theory could be: Trying to remove the glue from electronics components with water and soap could then lead to damage to the components because of the water and the soap (possibly on the long run) ?

The usual route, though, is to let the factory epoxy all the wires to a chip, and folk in the field connect the wires (using conductive glue, i.e. solder). So, the conductive glues are more important for the end users. |

Bye, Skybuck. Water soluble = conductive. John |
