The only silicones that are electrically conductive are those that are 
loaded with some conductive material (like silver). These are rather 
esoteric and it is very unlikely that you would encounter them. On the 
other hand, many silicones are rather thermally conductive.  Perhaps 
this is the source of this misconception.  Also, Room Temperature 
Vulcanizing Silicones (RTV's) are, also, well, obviously, silicones. If 
removed with care, they should not lift traces, although, again 
obviously, too heavy a hand will remove traces from paper-phenolic 
(those brown ugly things) circuit boards. It would be really hard to 
lift them from epoxy-glass material (usually green).

Nevertheless, hot melt glue is a fine choice. It hardens quickly, is 
easy to apply and is electrically and chemically inert.
