Dale,
There are a lot of similarities, yes. I at one point or another contributed to both documents. The 001 is the process spec, the 610 is the qualification spec. They are used by two different groups within the factory. The 610 is really all about the artwork/visuals. The 001 is what the process engineers would (in theory) use. Remember that the 610 was traditionally used by the commercial guys and the 001 is the offspring of the DoD's Mil-Std-2000 and the IPC's own (mostly ignored) soldering spec (whose number I can't recall * 815, maybe?). The big primes at the time (TI, Lockheed, Hughes, Raytheon, etc.) pushed for a joint standard, hence the "J," and really drove the spec. There was a lot of tutorial/process info in the early versions of the 001; most of that has now been removed, with the idea that the spec should tell you where you need to go but not how to get there. Later, the 610 and 001 task groups started holding occasional joint sessions to iron out the differences between the documents. Which brings us to where we are today.
Anyway, you probably weren't asking for a history lesson, but that should shed some light on why things are the way they are.

Hi Dale,
We've always thought of J-STD-001 as the "how to" book and the IPC-A-610
as the "inspection criteria".
I believe that if you combined the two you'd end up with a pretty big
document. We like having the 610 on the line as a reference without all
the verbiage of the 001.
Just my Thursday $ .02!

Subject: [TN] Differences - Similarities between J-STD-001 and IPC-A-610
After reviewing each of these documents I have to ask - why have both?
They
cross over on so many lines I stopped counting. I suppose I'm missing
the
most obvious, but it looks like we have some unnecessary duplication
here.
Need your opinions, please (humble or otherwise)... Why have both? What
are
the intrinsic differences between them that make it imperative to have
both?
There must be some since we still use both. Can they be combined into
one,
all encompassing document? If not, why not?
Just waxing philosophical this morning and would like your opinions in
the
matter.
Thanks in advance,
Dale Ritzen
