Ioan,
Unfortunately it cannot be freely distributed. Earl being Earl, did not
bother to get permission for many of the tables and figures in his book.
He asked me to edit his book at one time, but he did not take criticism
(well intended) very well and that venture came to a quick end.

Subject: Re: [TN] PCB Design Rant - Concurrent engineering twist
Hello distinguished members of the Forum,
I guess many of us remember Earl Moon and his DfM/CC book. Not so long ago I
inquired of his whereabouts and it seems he passed away. In this case, I
guess the aforementioned book is not bound to copyrights anymore, so it
could be freely distributed. I personally believe that circulating his
comprehensive handbook could benefit to all, including the younger members
of this group and would keep Earl's memory alive. He put his heart into it
and we owe him one!
So, I am one of the owners of the CD originally put together by the author
and, if all legalities are clear, I could upload it on IPC's Technet website
for free download. Or I could share it with Steve G., so that he puts it on
his page.
But once again, I don't know how the copyrights work and do not want to run
into trouble, so anybody could help from this point of view?
Regards,
Ioan Tempea, ing.

Objet : Re: [TN] PCB Design Rant
Brian, that list needs to be presented to every Engineering VP! I wish I
had that a few weeks ago, when we were putting to gether our "how to fix
this mess we're in" presentation. Yup, a few years in to our brilliant new
plan to cut costs in Engineering, we were tasked coming up with a plan that
could easily have started with "I told you so"
It's not about about new, fresh out of college, any of that. It's about
areas of expertise and resource utilization. Brian's list very completely
described all of the things NOT taught in engineering school. And, it's a
list of things that a properly utilized EE just doesn't have time to deal
with. That's why there (used to be) PCB designers.
Our case study: We used to have a group of PCB designers, working very
closely with in house engineers and captive PC assembly. We bought a
smaller company in Europe, they had no PC designers, EEs did the free CAD
thing, but they didn't manufacture much. Upper management then decided PCBs
are electrical, EEs can design them. China is cheaper, open an R&D group
there. I am now the only PCB designer in a company of 4K employees. We
closed our captive facility and outsource assembly.
Our Europe EEs are excellent EEs, but don't understand PCBs, so I spend way
too much time with vendors trying to get their expensive and unreliable
boards built. Our China group has very little technical experience, and a
culture that discourages independant thought. So while they bill 1/3 what
the US bills, designs take 4x as long, I spend 1-1/2x as much time
handholding as it would take me to do the design. And still, that time with
the vendors building poorly designed boards. Our EEs in the US, having
worked with PC designers, have been able to get their design work put on my
overloaded schedule.
After 3 years, that same management asked us to figure out why our time to
market and product cost has grown exponentially. The first suggestion they
shot down was to hire another PCB designer.
