Terminal Grease
 
I'm trying to find info on a contact grease that is used by VAG group.

I read about it somewhere but cant remember where.

It is to prevent contact corrosion and it improves the electrical contact thats in direct contact with each other but not conductive between adjacent terminals if that makes sense.

Anyone know what I'm taking about?

Dielectric grease?

No Di electric by its nature prevents conductivity which is ok in places like spark plug boot but not so good on electrical contacts.

The grease that i read about improves conductivity on contacts but at the same time is not conductive across bigger gaps for example between terminals.

Sounds impossible to me but I'm sure I read about somewhere. :Confused:

Not sure about the grease but there are conductive adhesives and tapes that have a base material non-conductive and then they have lot of microscopic glass or metal spheres in it coated with silver. So when the glue or tape is squeezed to the thickness the same as sphere diameter silver coating conducts the electricity vertically but there is not enough spheres in the glue to make connections and conduct it horizontally. I guess the same principle could be used for the grease.

If anybody is interested I used such tape from 3M to successfully re-bond ribbon cables to the PCB in the 46" Samsung LCD panel when one of PCB's was liquid damaged. I got a second hand PCB on e-bay from a TV with smashed screen. Was not easy to get it as nobody actually takes the panel itself apart, just chucks it out if it is smashed and sell the rest of stuff from TV. Took me a lot of hunting until I found a guy selling spares who had not chucked the screen out yet so he took PCB's out of the screen for me.

Here is the link to 3M product : http://solutions.3m.com/wps/portal/3...4001720&rt=rud Expensive to buy as a roll but there are people selling it by the length on e-bay.

Found it
 
It wasn't grease in the end but this is the product I had read about.
