Hi TechNet!

In a former life, I met the late Jim Bryan and was treated to several
lectures on "What a 'process' is".  He also wrote a series of articles on
this subject for PC Fab which I no longer have (sometimes you just have to
clean house).

Does anyone still have a copy of these articles they could fax to me?
Please reply offline.  Also, I WILL contact PC Fab myself.

Also, I would like to have the TechNet's opinion of what a 'process' is to
them.  I am about to enter into this discussion with a bunch of assembly
folks (I'm just a board guy, you know) who think I ought to be able to spec
in the boards so they can go through all of their 'processes' no matter how
they control them, several sites, one material.

As I recall, (and, trust me, I used to be able to recite this in my sleep)
Jim said that the process window had to be large enough so that a variety
of materials can run through without a change in process parameters, and
all of these materials will acquire the desired characteristics of the
outcome of the process.  In other words, you shouldn't have to change your
process every time something different comes along and you should be able
to run a lot of different materials through your process.  A robust process
has a window you could drive a truck through.

Anyone care to continue this discussion?  My apologies to those who don't
like this sort of thing on TechNet.

Regards,

Dave Sullivan
