Wire Glue (conductive glue)

I'm gonna try using this carbon impregnated glue to repair a few old remote controls where the pads have become none conductive..

Anyone done this before??

Not tried this one, but did used to use a "silver" track repair glue years back.

Interesting stuff, let us know if it works Kymmy, I wouldn't mind having a play with this glue

Looks like a good product, but I would get my mum to solder it as she has done a military spec training course in soldering.

Soldering plastic buttons doesn't tend to work all that well though :p

Looks good stuff Kymmy, Do you reckon this would be any good in resticking the Heated Rear screen tabs when they come off?

I used to rub mine with a pencil. I believe the harder the pencil, the more graphite will be deposited.

That's an old trick that I also used to use to overclock CPUs in computers.

Nope, it's not designed for high current applications

The blacker the pencil the more graphite (darker color) the harder pencils have more clay in them for the hardness

Not good though for remote controls as the carbon in just deposited on the surface and will eventually come off leaving a conducting mess floating around the remote

Thanks, Fair comment.

http://www.tedpella.com/SEMmisc_html/SEMpaint.htm look down the page for Silver Conductive Epoxy

The item after that is apparently OK for low current conditions too

Results of first test..

Old remote from a sound system in the workshop that I've used with oily fingers for years, the oil soaks through the rubber buttons and eventually stops the carbon pads working..

So I removed the rubber keypad, used some light grade sandpaper on the carbon pads to remove the shine, wiped down with a bit of solvent, left to dry for 10 minutes, then applied a thin coat of the glue. The glue was fully dry in a couple of hours, reassembled the remote and every button now works perfectly..

Going from the amount used from the 9g pot I'd suggest you could use this for anywhere between 50-100 remotes (not buttons but 50-100 whole remotes)

The glue is water based so if it gets too thick you can add a drop of water and stir.

I paid a fiver for the pot (that included delivery) from http://www.smallbattery.company.org.uk/ though it is available on ebay from the states for roughly the same price.. Delivery was an excellent 2 days.

In the end I'm happy with the product and results though coming from an electronics background I don;t think I'll be using it for circuit repair instead only specialist repair such as remotes, flexible boards or other such circumstances

Thanks for the feedback on this Kymmy. Always nice to hear.

Yep. For years. In my experience it's not the PCB that becomes non conductive but the rubber in the membrane perishes over time and thus becomes non conductive.

I have not played with the paints, but a small piece of silver foil super glued to the inside of the pad, the bit that presses onto the PCB does the trick.

You need to dispense the super glue with a pin and a steady hand.

[Kymmy]

If you read on past the first post you'll find that I was talking about the rubber carbon impregnated pads

I used to use the silver foil and superglue trick but the glue never bonds to well to the aluminium foil due to two factors (1#It's not a good keyed surface for the glue to adhere to, 2# The glue goes brittle with age) Both means that the silver foil drops off and you get a shorted out remote.

Been using the test remote now for 3 days constantly and it's great, checked the glue to make sure it's stuck OK and they all seem to be holding up

Just a quick update, 2 weeks later..remote in heavy usage, no problems so far
