Hello,
I am looking for data on two questions:
1.  What is the average/acceptable yield of a PCB assembly line?
2.  What is the average up-time of an SMT line (do most lines work 7
days-a week, 24 hours-a-day or what part of that time).

I would be very grateful if you could provide such data or suggest
appropriate sources for such information (including publications
available for purchasing).

Thank you.
