Is that the right number? I'm trying to look for it, but am not seeing it, at ipc.org. Maybe IPC-2612-1?

Interesting stuff all. From what I can tell (here and on another
forum), there isn't really a clear "standard" to either BOM's or this
issue. [Nor to parts that are installed after testing the assembly.]
I've seen DNI, TBD, SOT, SAT, DNA to describe these parts! It seems
that any naming convention can be used, with the knowledge that it will
have to be explained (DNI means don't install, SAT means something will
get installed at a later date, etc).
