Hi All,
        It simply isn't true that a Fuji CP 6 cannot place 0402's.

        We have placed several million this way.  Now I won't say that
there haven't been any problems but thrown caps are not the leading
defect.  For our process (2000 placements on first assembly) the leading
defect has been tombstoning.

        The defect level on first assembly was taken from 20,000 DPM to
200 DPM.  The second assembly is still under developement.  In fact after
I finish this email I will resume my developement.

        So I can't say that the Fuji CP 6 never throws the 0402's.
However I can say that it is happening for us less than .02% of the time.
(BTW .02% equals 200 dpm).

        I guess I could determine the rate for missing component related
defects on several packages, 0402, 0603, 0805 if only I could find the
time.
