<< Dewey,

 I think within 2% fall out is ok for any chip shooter. I have worked with
 Mydata TP9-UFP & Fuji CP6 & this is good approximation  for chip component
 fallout.

Hi Dewey,

     I agree with Ashok, 2% ain't bad. Actually, when we quote supplying
attrition with the kits to our customers, I like to see 3%...but sometimes
the buyers who supply us material think they're doing a good job when they
give us exact quantities...1000 boards, 1000 parts....sheesh...
What really kills me is when they give us the 1000 parts in 100 piece
strips...fun stuff there...
