Hi Joe,

Thanks for your response.  We appreciate your opinion.  A few points I'd like
to comment on.  I don't think that simply looking for ISO certification
qualifies a PCB shop as a "good" PCB shop.  In fact I've been in some pretty
poorly run ISO certified shops.  And, no disrespect for our hosts here, IPC
membership certainly doesn't make a shop competent.  Any shop can become a
member.

Of course any end user that would want to audit a PCB shop with more than one
facility would need to take that into account.  But as a PCB manufacturer
don't you audit the facilities where your cores and pre-preg are made?  If
so, don't you go to that specific location or do you allow a multi-unit
material supplier to ship to you from any facility.  Maybe you don't audit
your material supplier, I don't know.  But clearly, using one shop's "grade"
to measure the quality from the sister company doesn't make sense.

And the last thing I'd like to comment on is toward your last item, what
third party would be qualified to audit your shop.  Well, certainly end users
who have never manufactured PCB's are not fully qualified.  But a group of
PCB process engineers, quality engineers and manufacturing professionals
would probably be.  People who have spent a minimum of 15 years (each) in the
business of manufacturing PCB's.  Maybe even people who have, at one time or
another, worked at your shop.

Again, we appreciate your feedback.  We're just beginning the "thinking"
portion of this venture and may not even proceed with it.  Just seeing if the
end user community would benefit from it.

Thanks.

Mark Mazzoli
