Hi Rich,
In a previous life, we used EIA-481, with the exception that we designated an
"inpack code" (such as 258347-1=m7a, where the "=m7a" is the code) on the end of
our part numbers, which had two purposes:One was to let everyone in-house know
that this part number was packaged for surface mount or leaded auto-insert
(i.e., not bulk); and two, the inpack code had an associated inpack code drawing
that gave specifics for each code that went beyond EIA-481 (example:=m7a was for
8mm tape and reel and may give extra info for parts on this size tape, such as
tighter specs) and purchasing would send this inpack drwg with parts orders to
the suppliers. This works great if you have enough special cases to warrant it.
Also, I've worked for companies, and I know a lot of people, that rely on
EIA-481 alone (it is overall, a pretty good spec), which works great until you
run into those few "unique" part issues, or have an older radial machine with
tooling that needs shorter leads in taped lengths then the spec allows, then you
have to micro-manage those issues with the supplier, or creat a small addendum
spec to go with all radial orders.
It is obviously a balance between the level of documentation you are willing to
create/control in-house, and if everyone (purchasing, incoming inspection,
quality, mfg eng'ing, etc.) will support, and the amount of mfg'ing headaches
you see from those few unique instances.
Not sure if I answered your question, but good luck!

Hello TechNetters,
I am in the process of setting up in-house standards for the presentation of
SM components and their packaging. I am curious as to what other people are
doing within their own company. Since I do not have any personal experience
in this area, I do not know if just saying "We use EIA-XXX,......" is enough
or not. I would suspect no.
Do you just accept the EIA standards as is? Do you reference them in an
in-house document? Do you create your own?
If you are willing to share any such documents with me, I would be most
grateful. Contact me off-line and we can work out the details of such
sensitive information.
I am a bit leery to just accept a vendors statement that they can supply
what we need, the way we need it! Call me skeptical!!
Again, I wish to thank everyone for their feedback on this.
