Now don't open your presents all at once!
Save some to read for the rest of those long dark winter nights .

Hi all,
after the request for books about analogue electronic design, I
thought it might be nice to see whehter there is any book about PCB
design. In particular I would be interested in the magic and voodoo
parts.
- pcb materials, electromechanical consideration, etc.
- crosstalk, stray

Hi Torsten,
Have a wander round:

and

After all, push your signal fast enough and you can no longer treat
the PCB and the schematic as separate entities.
Cheers,
Andy.
High Speed Digital Design: A Handbook of Black Magic by Johnson and
Graham is a great text for anyone interested in signal integrity and
EMI. It's no spring chicken, but PCB technology hasn't actually
advanced much these last 16 years; it's just gotten cheaper and more
available. I found the

Currently we start new layouts in PCB with a bunch of footprints auto
dispersed.
As Kai-Martin said recently, position of symbols in schematics is
closely related to position on PCB.
May it make sense to start a new PCB layout direct from a view with
symbols? Clicking on a symbol (or selecting

Ok, I toyed a little with this. Spaces are successfully
Peter Clifton:
I just came across a proposal to remove the tear-off menu feature in
GTK. Whilst generally none of our business how up-stream tool-kits alter
their UI - outside of its programming interface, I was just wondering if
anyone actually used the feature?
Since I am new to geda, I
It takes layer GROUP numbers, or layer NAMES. Layer groups are
numbered starting at zero, just for inconsistency.

_I_ should have been clear: I did speak to the developers via a comment
to the bug report you linked to. :-)

The main advantage there is that you could place each component by

This is how I delegate the find task to the computer:

Sure. This is what every EDA suite I had the chance to have a look at,
does it. After all, the schematic provides an intuitive
You know what would be cool? Being able to drag and drop symbols from
gschem into pcb, and have it load the right footprint.
