Steve:
If I may suggest a two pronged attack....
As one experienced in QT and production boards, I have found no loss of
turn around capability due to ISO. High end process control is what it is
afterall and
should result in high yield (low waste) performance when adhered to.
(1) Clearly, I suggest ASAP DFM as quickly as the design allows is of utmost
importance.
(2) I am a believer in the Deming Principals of Co-Operative Engineering.
That is....at the proto-type stage, involve the PCB fabrication supplier,
assembly engineering, test AND service to design in the best value.
The result is a quicker to market design.
With designs demanding leading edge capability, there should be NO EXCUSE
ffrom qulaity suppliers to cut corners due to a board being proto-typed.
The benefit is that in fact when the proto is built...it will reflect the
production quality as well therefore negating re-engineering.
This is what the Industry has evolved to out of customer demand in my view.
And let's be frank, as the industry continues its writhing is it not true
that customers are using ISO as a litmus test for building product?
Customers deserve nothing less Steve, reagardless of the quantity.

Hi peter!
I understand your reasoning, but when it comes to prototypes, nine-times
out of ten, the board is going to change...most of the time anyway.
My intent is to figure out a way to turn these prototypes as quick as possible.
These assemblies are like a newborn child with expectant fathers waiting
on them. Going through the normal, full-blown, ISO production stuff, seems
to me, wasted time....
Yes, our customers want the assemblies built to industry standards, but
I feel that there is no need to go through all the processes, documentation,
etc...that a normal production product would need to go through...prototypes
after all, are only to prove the design, no?
Out in California, when I worked for companies out there, if we couldn't
turn a proto in a couple of days, then the customer would look for someone
who could. Most of the time, the companies that could do that for them,
would get any follow-on production if the product was viable...
I just have a hard time understanding ISO and prototypes...I would think
there should be a way around all the BS...

Hi, Steve,
Personally, I try to put Prototypes through full production processes just
so that there are as few surprise lessons to learn as possible. All the
R&D
work should have been done by then and our "Prototype" models are the ones
that have to go through all the qualification testing. No sense in making
them one way and production boards a different way or your qual testing
means nothing.
