Dear George Kotecki,

The parts on my schematics also list our internal company part number.
(Purchasing uses this to lookup into their database of who they purchased this
from last time, what their part number is, alternate manufacturrers and their
respective part numbers, how many we have in stock, what price we paid last
time, etc). This is used to discriminate between the several incompatible kinds
of 10 KOhm 5% resistors we use. I use part number "(unstuffed)" (rather than
something like "#01234") to make sure that "part" is never actually purchased.

Quoting from http://www.egroups.com/files/protel-users/protelfaq.txt
:

Occasionally you have "parts" that you don't actually have to buy. For example,
connectors that are only needed on the prototype board, left off of production
boards. Or fiducuals and RF "components" that are really just patterns in the
copper. Since my purchasing agent panics when a part is mentioned on the
silkscreen but gets left off their BOMs, I put "(unstuffed)" or "(unused)" or
"prototype only" or something similar to reassure him that this is a complete
BOM and we aren't forgetting some crucial component.

Subject:  [DC] Embedded Resistors




Greetings,
        I am looking for a little help regarding embedded resistors.  This
is not a true design issue but rather an information issue.  We intend to
treat them as  parts as far as the CAD system is concerned as opposed to a
feature.  On the schematic, each resistor will have the usual set of
attributes: ref des, value, tol, pin num.  When we run our parts list, these
show up as discrete parts.  What schemes are used to make sure they are for
internal use only and some purchasing agent won't try to buy them?  TIA!
