Yeah, I know what you mean...

Even though we have been hearing for years how important it is to
"maintain a good relationship with our vendors", it isn't always that
easy. At the joint venture I work at currently, a vendor is forbidden to
contact me directly. He has to go through the sales rep to the purchaser
to the program manager and maybe through the project engineer too, and
usually the labyrinth of bureaucracy has garbled the original question so
much, I can't even understand the problem without calling them directly.
The only purpose of this "control structure" is so that any changes I have
to make are broadcast to the entire universe so "everyone is on the same
page" and no one feels left out.

But you know what the end result is?

They just don't call anymore, they build it however they think is best
without asking questions.

insane.

Your question just triggered my need to vent, sorry.

best wishes in your dealings with your customers,
Jack (the "all alone in a little cubicle" guy)

Jack,

I wish there were designers like you at the customers
we deal with...and sometimes (to make the communication
problem even worse), a design is not our customers design,
but something they have outsourced.

But even if you do get to communicate with the actual designer,
and then find out that a note on the drawing is pretty meaningless,
and makes the fab that much harder to build, many times I have
heard; "Well, if we remove the note from the drawing, that'll mean
we'll have to roll the revision on the drawing, and that's just too much
trouble..."

Kind regards,

Why are vendors so reluctant to ask the customer what is the intention
behind their vague notes?

As a board designer, I wish vendors would just ask me what I meant,
instead of trying to get a consensus on a forum.

Re: SMOBC question...
Hi Jeffery,

The board that I'm talking about doesn't seem to be that old
design-wise. So do you think that maybe the note is just something
kind of got "boiler-plated" from earlier designs?

A description of the board is that it is a VME styled board, and
everything
on the board is SMT including headers, right angle push button switches,
etc., the only through-hole is two press-fit right angle connectors. So
the
board is never going to see wave solder.

The board is 15-layers and only .065" thick. Do you think that maybe the
reason they have the note prohibiting HASL is because they don't want
to thermally shock the board which may cause other problems?

Kind regards,
