Do you layout your own boards or have a pc designer lay them out? I
suffer from extream anxiety when I have to deal with some pcb
designers.
In general, my employers have arranged things so that printed circuit
drafts-persons have laid out my circuit designs.
The very fast or very precise stuff, you have to work fairly closely
with them, but with a good drafts-person, a page or so of notes, and
some layout notes on the circuit diagram ("keep this track as short as
possible and well away from track X") gets you most of the way.
We'd check the layout after the drafts-person had done a placement and
again when the basic tracking had been done, and then go over the
board effectively checking the layout agains the net-list, more to
make sure that we looked at every trace than to confirm that the
layout followed the circuit diagram.
I have laid out a couple of small, fast boards, and I don't think that
I did any better than a good draftsman would have done.
I've also seen - and fixed - some truly appalling layouts. there are
quite a few mediocre drafts-persons around.
England being what it is. I mostly worked with draftsmen. The one
female drafts person I can recall was very good. Her father, who also
worked for Cambridge Instruments as an instrument maker, was both
exceptionally bright and exceptionally careful, and I imagine that she
was better than the average female drafts-person.
