The closest to success we come is involving the following folks for a design
review:
Designer
Assembly Engineer
Component Engineer
Test Engineer
Then, we pull in the supplier and do it again.
It can be a lot of fun! We get into conversations like this.
The assembly engineer says, "I need fiducials."
The design engineer says, "You can't put them there."
The Component Engineer says, "How will the supplier build it like that?"
Hopefully, all the tradeoffs are discussed so everyone gets what they need.

Haha I agree with you Graham. I come from 20 years in assembly. So I do
look at things from that angle. Now I have to start looking at them from
the electronics side too.

Hi Ken
Well, from the other side of the process (I'm an assembly guy), I have
always encouraged the designers to get the design reviewed by the people
who will be building it before the layout is set in stone. We may
notice things that you won't, and this has saved us some "oh #$#!!"
moments.

Hi Folks,
2 years ago my boss gave me the task of learning board layout. It's
something I wanted to learn to do, but have been frustrated on the lack
of
resources available.
Over the past 2 years I've managed to learn quite a bit, and each
layout I
do is progressively more complicated. The last board I worked on, was
a
very dense 8 layer board, with several .8 mm BGAs. The board is up
and
running, but there were several mistakes on it, and will have to be
turned.
I've been trying to think of ways to check and recheck my designs and
I
wanted to find out what others do to verify the work they've done.
Thanks for any input.
