Brian,
        We use AOI inspection at post reflow.  We have a VT-8000system
from Orbotech and have been very pleased.  I also evaluated Theta
Systems.  I feel they have a decent system but it is better at
pre-reflow.  I don't think they have enough experience at post reflow.
Programming seemed too time consuming to get a reliable post-reflow
inspection program.  The first question you need to answer Brian is 'Do
you want to inspect your product pre-reflow or post-reflow and why?'

Best of luck.

                I would like to know who all is using vision inspection.
Is it worth it
        and has anybody heard of Theta vision systems.
