All,
     We have discovered that a thermal pad placed between the backside (non-component side) of a PCB and a chassis oozes significant
amounts of silicone oil.  There are several feed through holes that allow the silicone oil to flow to the component side of the board and collect
around various components.  We have not yet experienced any electrical issues caused by the silicone oil, but I was wondering if anyone could
help me get a better feel of whether this is truly a problem or not.  There is a chance that the silicon oil could get onto a RF microscrip (Rogers
6010 LM duroid material) board.  Any thoughts?  Thanks very much for your insight!

Regards,
Eric Stellrecht
