Does anybody know of a temporary trench-filling material other
than water-soluble or latex-peelable solder masks?  I need
to fill a trench 0.012" deep by 0.012" wide by 1.900" long.
The material must withstand solvent chemistries, have relatively
low-outgassing properties (vacuum environment), and be removable
at the end of our fabrication process.  Any suggestions would
be greatly appreciated.
