Re: Question regarding using epoxy or RTV on PCBs

I just use whatever clear silicone is at the hardware store. I
do smell the acetic acid in silicone.
Did you know you can make copper bright and shiney in vinegar?
Vinegar has acetic acid..
So I wasn't worried too much about home silicone containing some
"Alien" acid that would eat through the floor.
If there are corrosives in the RTV..the reactivity I believe is
limited and reduces to nothing after cure. Some microscopic
copper loss can be tolerated.
I don't like the RTV slow cure time and the hot glue suggestion
below from another poster is something I use frequently.

Hello..
I am trying to repair a circuit board which has a couple of
obsolete
components. These parts are unavailable and it appears that I
am going
to have to resort to 'cludging' an alternate part in order to
getting
the pcb back up and running. To do this, I will need to bond
the parts
to the pcb in some fashion, using some insulation material
between the
component and the pcb. My desire is to use clear RTV in case
I need to
possibly remove the part at a later date.

The question is, how safe is using RTV on pcbs? Is there some
corrosive
properties that possibly take place later down the road? I
would guess
that some formulations of RTV are better than others in this
regard.
Your ideas and suggestions would be appreciated.
Thanks -

Hot glue works well as long as the unit does not operate in a
hot
environment,like a car's interior on a sunny day.
