Dear Mike,
A clean room of 'class 10,000' as per FED-STD-209 SHOULD BE OK.

Good day Technet community,
I would like to draw on the experience of those in pcb fabrication
and ask for opinions or advice regarding the need for clean working
areas in the pcb shop.
Our laser plotter / phototool production area and photoresist
lamination / exposure operations have been identified as 'not clean
enough' to reliably produce 4 mil lines and spaces. We do OK
down to 5 mils.
These areas are already 'nominally' clean but separate
departments and the plan is to intergrate them into a single
upgraded operation in a new location.
If it is advised that this should to be made a classifiable clean
room, what Class level are we talking about? If not, how clean is
clean enough?
Mike Holst.
