OBA

Hi all,
Good afternoon. Here I just want to ask for some questions about OBA. Do you have OBA procedure in company? How does it define this procedure? Where does it occur? Before W/H, or after W/H? I just mean that the finished goods are sent into W/H. Do you have FQC, OQC and other inspection function? How about your sampling rate or level? And OBA? Do all need to follow MIL-STD-105E LEVEL II, or toher sampling method? Thank you!
