Well, certainly you have ∗many∗ fine MOTM example pcb layouts to look at :)

I don't want to give away too many secrets, but here some general rules:

1) use 15mil trace to connect signals.
2) use 50mil trace for power & ground.
3) use pad sizes of 80mil, with 40mil holes
4) don't 90 degree bend the 15mil traces. 50mil is OK.
5) use 50mil pads with 28mil holes for vias.

Have fun! I find it relaxing (for easy stuff! The next 2 layouts are nightmares. For Maxim, I'm
starting a 6 layer, 10 x 10 board at 100Mhz speeds. 5ns SRAMS and a 248-pin Xilinx part)
