Board Design Documents
This is a document from a PCB fabricator that is old but still useful for the guidelines in it. It gives guides on direction of layout vs flow and sizes of fiducials and such like.

Texas Instruments - PCB Design Guidelines For Reduced EMI
Here is another document that is quite good. Its not that good on multi-layer stuff, but gives a reasonable over-view.

Re: Board Design Documents
...and here is another one from a large European fabricator. These are always quite good in order to get the board actually made properly; but, of course, they don't care if it actually works.

Re: Board Design Documents
From first post doc: The routing of traces out from passives is good. Most of the rest is either obvious or not applicable?
Second one has a lot of good stuff in it, but this caught my eye for a LOL:
MegaSquirt, always the worst possible choice ;-)
The second one, the TI one, is an excellent read, thanks! :-)
PCB details one is good to know, but mostly automatic anyway.
I hope both Andy and Dan read the TI one, and maybe the first one too.
Fred.
