Pete, et al;
As a designer, I find the greatest difficulty and frustration in
advancing my topical knowledge is twofold; time and money. We, more
often than not, simply cannot take the time (deadline pressures) to
attend the workshops or conferences that we'd dearly LOVE to attend. Or,
as is the case in today's economy, our employer is not willing or able
to pick up the fee and I certainly cannot afford to pay for it out of my
pocket.
As a kudos--- THANK GOD for the designers council! Were it not for our
regular chapter meetings, I'd never have the opportunity to hear from
experts in the various disciplines.

Subject: Re: [DC] Fw: [DC] questions please
I've been watching this forum for the last few days and noting the
(limited) discussion of DFM. Personally I am quite befuddled ( I
searched but couldn't come up with a better word). Over 10 years ago PCD
started a crusade on DFM. We organized discussions with designers and
manufacturers, printed umpteen gazillion articles in the mag, devoted
entire tracks to the subject at the conferences, yadda yadda yadda. It
just seemed that people really were not concerned. Granted there were
and are a core group that grasp(ed) the importance and impact of DFM,
but the great masses seemed to take the point of view that they had
been sending out data packages and getting back boards so everything
must be ok. Meantime the shops were saying that the easiest and fastest
course was to fix what was wrong and build the dang thing so they could
invoice it.
Has anything changed? Well, as I said there is that core, but times are
tough in a lot of places and I certainly understand that keeping ones
head down and not make waves may sometimes may seem to be the best means
of survival in the short term. But the thing I really have trouble with
is that the manufacturing community and the suppliers to that community
keep telling us that they want to reach the designers and have a true
exchange. They have sponsored and organized seminars on the subject,
some of them free. But in most cases designers are not taking advantage
of these opportunities. As an example, one person wrote to us to
complain about our exhibitions at the conferences, specifically that
there were more board fabricators exhibiting than EDA vendors. Think
about that a second. Aside from the fact that there just aren't that
many PCB EDA vendors anymore, I'd say that it is as important, maybe
even more important, that they know and understand their board vendor -
their capabilities philosophies etc.
I'm gonna go now, I get frustrated on the DFM subject. Sorry for the
length of the post, but it's been so long since I wrote an editorial I
forget when to get out.
Good luck and hang in there. Trust that someone is listening. p.

Jack,
It really is amazing and very gratifying to see how far we've come.
You're sure right about technical people writing for others technical
instead of trying to sell something.
Concerning the issue about designers improving I can say without a doubt
the biggest one is NOT HAVING THE TIME, as you say. It may not be the
designer's fault but that person has to make a strong appeal to
management to make more time to do it right up front - starting at the
schematic level.
How many times do we say "I don't have time to do it right but I've the
time to do it over?" Those words just seem to come out of our mouths so
easily but what a shame we have to say them when all the answers are
there. One example is when someone releases a design thought to be
complete but some of the most important things are missing as good
drawings and specifications with which to communicate requirements,
qualify suppliers, and accept or reject product.
I'm sure you, as well as the rest of us, have seen way too much time
WASTED dealing with good suppliers that do a lot of the DFM work we
should have done but for lack of time and the ability to COMMUNICATE
clearly our needs. I can't tell you how many times I've helped folks
qualify better suppliers that can be worked with concurrently when the
proper language is used. If not, a design package is sent out and it may
take several weeks to resolve all the fabricator's or assembler's DFM
issues when it should take two or three days at most. Of course, that is
more difficicult now dealing with Chinese suppliers - as one example -
because many of them don't speak any language but price.
I've been in a lot of companies both crusading and teaching really
interesting technical stuff but I learn far more than I teach and that's
what I want to do here. I want to take this time to do it better next
time.
