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!
