Well assuming that the parts are genuinely damaged when rejected and you want to rework them to reduce scrap,you could use a shadow graph and get the mechanical spec on clear film.Then rework accordingly you should be able to rework most leads.

This happens when either (1) good intentioned, but not clear thinking people or (2) BAD sales types with poor skills looking for excuses to push their product open old threads that were originally posted before the last conversion of SMTnet to Cold F

Ken: At the end of arguing about how �myfloh� is calculating defect levels, reality sets in. �Between 50 and 250 ppm� is pretty darn good. Clearly, they have picked all the low hanging fruit.

Thanks for the suggestions. I should have been more clear when I said "loose parts". Along with the truly loose parts I have many strips of 50 to 1000 on reels (not marked) and in bags (not marked). I guess if I cannot determine all of the tolerance

Huh?! The area of a square that fits in a circle is clearly less than the circle. Paste release is better in a circle than a square because the circle has maximum area per perimiter lenght.
