Nothing is through-hole and affordable any more.

I heard of a prototype PCB material where one of the inner layers
were carbon-based and could be used for heating the entire PCB in
order to be able to space-qualify SMD boards.  Havn't heard anything
about it since though.

I've never had trouble with it.  Most electrolytics are spec'ed for
-40C .. 55C or similar.

Now heat on the other hand: that's letal to electrolytics.
