There was a very good article in the March 1991 edition of EDN 
     magazine, pages 59-64, on the use of lubricants on electrical 
     connections. The article also contains several additional references 
     that may be helpful.

We are looking at a unnamed manufacturers board that has several connectors 
mounted on a board.  The connectors are soldered on one side of the board. 
 The connector pins are gold plated, and appear to have a silicon type 
lubricant on them.  Can connectors be purchased with a lubricant on them, or 
is it put on by the assembler, or should there even be a lubricant on the 
pins?  Could it be something else besides a lubricant?  I recall in the past 
that we put Dow Corning DC-4 on some rf connectors to prevent oxidation and 
water intrusion.  Appreciate any comments.
