Arcing, a reminder

Folks,

We are seeing an increase in arcing incidents in recent weeks.  Please
make sure that you take the time to inspect the trays and latches every
time you use the etcher.  Even if you are using all of the six trays it
is very important that you check all of them for burn marks.

It takes significant effort to repair acing burns after they have
occured.  In many cases simply looking at the whole hexode will catch
potential problems before they occur.  This will decrease downtime for
the etcher as well as lighten the load of the maintenance crew.

Thanks for your attention to this,

				Nancy
