Mark,

The customer specifies requirements OR, depending on several factors, each
supplier lot shall be sectioned and analyzed. For re-qualification to 6012,
the requirements are specified therein.

Back in the good old days, when processes were not nearly as well managed
(nor could the be considering what some of us had to work with) and boards
were complex for the time, we would test small lot sizes. When a board type
was particularly difficult, a lot of one might comprise the it and would be
tested. Obviously, if one board out of a lot of one failed, only one lot was
rejected. There's a lot more to this story and some of the other old timers
can add interest to it.
