Help finding quality electrical glue (Carbon Conductive ink)
« on: February 25, 2016, 07:13:46 pm »
Hello All:  :-+
  I have search High and Low on the web looking for quality carbon ink to repair an IR remote with carbon conducting switch. On eBay the only ones I see are the generic Chinese looking ones that some say it is not that all good and varies on resistance much.  Even the one on the link stated Made in the USA.  :-//
  I have search MG Chemicals, Chemtronics, Kester and CAIG, but have not found something similar to that on eBay that is not of questionable source / quality.
  What could be a good product recommendation to fix the remote pad? Is the eBay one good enough or just pos?
Will think about it.

I would look at conductive epoxy and/or rear window defroster repair kits. Both of those will be conductive and should be good enough to repair the damage you show.

Its not the contact pad, its a carbon ink jumper over the adjacent track.   I'd use nickel or silver conductive ink, for a significantly lower resistance than you can get with carbon ink.  There are various easy to use pen type products sold for track repair or to the maker community.

Don't need to be high quality or low resistance stuff. Al long as the resistance will be in the range of a few hundred ohms, there won't be any issue at all.

Peters SD2842 (sliding contacts) or SD2843  (buttons). If you request a "sample" you'll get half a liter of it for free!

Thank you all for suggestions,  Did not think about PedroDaGr8 rear window defroster kit idea. Now would need to source it. thinking auto parts store.
What about the eBay wire glue has any one used that before?>
Will think about it.

Buy a tube of Dry Powdered Graphite Lube  (auto parts store - Wally World, etc)
Buy a tube of "Non-Toxic Cement for Plastic Models"  - the standard solvent based model cement won't work.
Mix a paste and apply as needed.

I have tried a number of glues but only the Non-Toxic Glue seems to work after it's hardened.  The tube I have is made by PACTRA.

Are you sure is the carbon print that is the problem? Or is it the conductive pad on the membrane that is the problem?  Likely anything conductive that is not too hard shalll work (I think is the pad's problem), but get the smallest tube possible because the remainder shall be hardened up before your next use.

This is exactly what was thinking on doing. Will try it later on month end vacations.

Hello,
Well just a heads up, I ended up buying the product on eBay sold as wire glue by wireglue.us.  It ended up working very good for the repair of the remote carbon trace. Still prefer using good old soldering. But I must say this worked very good for what was required.
I played around with this stuff and there could be improvements like it being more tacky or more think. But this is now review.
Thanks to all suggestions. Is good to fix things.
