I apologize for the vagueness in my original posting.
This is what we know so far about this problem.

- It does not appear to be Z-height related - nozzles are spring loaded and
we have double checked.
- Breaks are complete breaks through the center of the body. Sometimes
the 'lid' comes off, but most often they crack top to bottom right through.
- We have *not* explored the possibility of moisture, but at this pont we
feel moisture is unlikely.
- The components in question are all placed on pass 1. We havent yet
checked to see if they are cracked before pass 2.
- It is not always the same part, but always SOT-23.
- The profile used is our 'standard' profile that has been used for about 3
years.

Regards
Virgil
