Hi
Two factors here. One is that the scanner doesn't have a
lot of the right wave length light. Two is that even a
piece of paper will absorb +99% of any of the UV that
would erase it. As long as there is something over the
windows ( almost anything ), I wouldn't worry.
When I was at Intel, we placed some 1702A's in direct
sun light for several weeks without data loss. A few
seconds in a scanner would most likely have little
effect. If you are concerned, put some black electrical
tape over any windows. If you don't believe that will
block the light try doing it on a separate EPROM and put
it under an eraser light ( you'll see what I mean when
I say that even a piece of paper is quite effective,
even in a strong UV light ).

So long as you cover the windows of any UV-eraseable parts with somethng truly
opaque, e.g. a bit of aluminum foil under some cellophane tape,I think you'll
be OK, Jeff.

Subject: [CCTALK] [CCTECH] scanners & circuit boards...
What's everyone's thoughts on placing
circuit boards directly
on the bed of a scanner for imaging? Any possibility of damage to
the board from the light or other parts of the scanner? I've done it
before with good results but not with anything truly unique.
