Steve,
   The necked down traces on your photo are actually Thermal connections to
a plane.

Hi Kathy!

It looks like they've done that with some of the pads but not with all of
them. You can see what I mean by looking at a picture I've taken of a
section
of the PCB. Go to:

http://www.driveway.com/share?sid=4eced0a4.94f42&name=Pictures&view=3

There you'll see the footprint for 4 components, a large cap, two 1206
parts,
and a 0805 part. I'm not sure if they necked down the traces to help with
soldering, but I still think I'm going to have a lot of problems if I try to
print paste and reflow...don't you?

Thanks!
