[sdiy] expo pair "heat shield?"

[drheqx]

We use a thermal potting compound to encapsulate military modules. The
silicone is not type one
( acetic acid ) and has minimal odor. The key ingredient is something like
sand or glass spheres
that conduct the heat away from the devices. The thing is in this case do
you really want the heat to go away
or do you want it to become a constant?  Old Tektronix vector scopes that I
used to repair by the dozens used a
brass looking "oven" to encapsulate parts in several areas. These
things had 25", I think, CRT displays and they were mostly
analog. They definitely had items that needed to stay thermally consistent,
but not necessarily cool.

Just a thought about the oven idea.
