Dupont has put together an article called "Perspective on Cleanrooms" which was reprinted in Printed Circuit Fabrication, Vol 12, No. 6, June 1989. George Murray ---------- From: TechNet-request To: TechNet Subject: Clean Rooms Date: Wednesday, June 26, 1996 9:01AM I have an interest in some practical information regarding clean rooms as they relate to printed circuit imaging and lamination lay-up. Much of the published information addresses ultraclean rooms for semiconductor manufacturing. If anyone knows of any technical articles relative to printed circuit clean rooms, I would be very appreciative. Ken Hafften
