 Gee, when I was a boy (and did that stuff for a living),
we used to head to the bookshelf, pull out the mechanical
data sheet, and make our own footprints. If it's something
interesting you draw it from scratch. In this case, take a
bigger or smaller version of the same package and modify
it.

 Using standard library parts without first consulting your
soldering/assembly contractor is pretty much asking for
trouble with SMD anyway. Library parts are never quite
right, doubly so with SMD.

I always used the manufacturers recommended footprint. However, there
is some standards org (that I cant remember for the life of me) that
has standard footprints. Most are pretty good, and i think you can
retreive one at a time from their website.

 Manufacturer's standard footprint (ie: duplicate the layout from
the spec sheet) would be as best as most soldering/assembly orgs
could hope for. What would not be good is to take the software
mob's 'standard' footprint. When you consider that some of those
libraries are built by putting the work experience kid in a dark
room and encouraging him to build as many variations on any given
theme as he can without regard for mechanical properties of molten
solder, cooling solder, etc, then those footprints may turn out to
be, shall we say, less than optimal.

I always got the work experience kid to do the footprints this way :)

You could always look here:

but you will still have to define the pattern for your PCB programme.

Thats the place thanks Alan. The last time i did a PCB layout
commercially would have been about 5 year ago now. I cant beleive how
fast time goes...
