I'm assuming that the members here on the IPC technet use IPC 610 to classify and rate their smt and through-hole defects.

I just wanted to submit a quick query to find out a general "state of the industry" to the following questions:

1.  Are you an OEM or contractor or other?

2.  Do you consider class 1, 2 or 3 defects (in IPC 610)?

3.  Do you track defect rates in terms of DPMO?

4.  What is your control limit for DPMO?  <100?  <50?

Thanks.
