Just curious if anyone recommends using dielectric grease on PCB edge connectors. I know that a lot of these connectors seem prone to corroding and burning.

Thoughts?

I wipe the pcb edge down with it after cleaning to prevent oxidation, works great. I just wipe a thin coat on then wipe off with a rag.
 
Dielectric grease is an insulator. You don't want to insulate the edge connectors from the socket connections.

radio controlled car speed controllers use contact grease to improve connectivity and reduce sparking.

imho clean connectors and regular cleaning thereof are good protection/preventative maintenance

Never. Think about how dirty things get inside a cab, then add something sticky like Di-grease... Sure to make mud over the long haul; If the connector needs help conducting, it simply needs to be replaced.
 
you want to use electrical contact cleaner.. not di-grease.

I hope this clarifies what i meant::)

1. Electrical Contact Grease is what i was referring to. see here as an example: http://www.ctlinterlube.com/CTL%20english/Application%20-%20Bechem%20Rhus%20SU%202%20Electrical%20Contact%20Grease.pdf

2. Dielectric grease is NOT conductive it IS protective against corrosion as Riptor said. see here: http://www.wisegeek.com/what-is-dielectric-grease.htm

3. IMHO cleaning is best, see above.

4. If you are seeing pitting, burning or wear, repair the trace.

5. if you dont maintain/clean regularly and you use electrical contact grease, then yes you could may up with "mud". simple fix though, if you use it, check/clean regularly with spray cleaner etc and reapply.
