Experiment to try to reduce arcing

My only concern would be that having the capton there would somehow affect
the etch rate. So I suggest that users report any etch rate strangeness they
see (too fast, too slow, etc).

Hi all,
   I have put kapton tape around the area of the latch slot on trays #2 and
#4. The purpose of the tape is to eliminate the arcing problem.  I have
noticed that most of the arcing has occured on sharp corners around the half
moon slot.  The plan is to put tape on each of the trays as they fail.  If
we get arcing on the trays with tape, I will either take all the tape off if
it arcs on an area covered with tape, or add more tape if it arcs on an
uncovered spot.  I have spoken with Jim Mcvitty about this and he didn't
have any problems with it.  Please let me know if you have any concerns
about this.

Regards,

Elmer
