I had never heard of this "kapton" tape!

Googling, I'm still not sure what it is, but it must be a great
insulator.

I must admit I was just using the name those who taught me PCB rework
used, though I _think_ it's correct. (The Wiki article doesn't mention
this specific use.) Though not perfect - the adhesive tends to weaken a
little under the great heat (and fair amount of wind!) required when
removing a largish chip - it does a pretty good job of protecting
(somewhat) the solder holding down the smaller adjacent components,
and/or holding those components in place if their holding solder _does_
get melted. The fact that it's transparent helps too: foil, as mentioned
by someone else in this thread, probably protects better, but you can't
see through it.

As we use it, it's on rolls, looking like thin brown "Sellotape" (UK -
Scotch tape I think US). I think the rolls shown in the Wiki article are
like it (though not sure if those ones have adhesive backing).
