Rios,
You have to determine the sampling plan based on the amount of defects
or rejects you encounter in-process, at the back-in or upon receipt.
If you have a high number of defects then your sample plan may need to
be higher and the inverse if quality and rejects are low. As a
starting point, I would use the C=0 sampling plan. If possible,
acquire "Zero Acceptance Number Sampling Plan," Fourth Edition or
later, by Nicholas L. Squeglia. This is only a starting point there
are other types of sampling plans available. The above mention is
from old days of MIL-STD-105E but are in good use today. Again the
sampling plan should be based on my first response above.

Hello everyone,
I am trying to set up a process for testing the solderability of components
and am following ANSI/J-STD-002. What I need help is in determining a
sampling plan for testing X% of parts from a lot. Any ideas are welcome.
Thanks,
