Paul, others will likely contribute, but I can't help expressing amusement
that the relatively new (2 years or so old) IPC-2221, is referenced in a
drawing along with what looks like the antique (cancelled 8 or so years
ago) IPC ML-950.  My recollection is that IPC RB-276 replaced 950, and has
in turn been replaced by 2221.  Lou Hart

Subject:        [TN] Specifications

I have recieved an assembly drawing the includes a note:

"Printed Wiring Board Assembly shall be in accordance with IPC-2221 and
ANSI/IPC-Mil-950 Class 2"

IPC-2221 looks to me that it is for the board design and is not
applicable to assembly specifications.  I can't find any information for
the ANSI/IPC-Mil-950 Class 2.

Can someone give me the specifics about these specifications?  Can
IPC-A-610 Rev C class 2 be used as an equivalent exception?

Thank You
