Re: gEDA-user: Enlarged footprints for hand soldering -- name conventions

["Steven Michalske" <smichalske@xxxxxxxxx>]

When i have made hand soldering pads for QFP with the center pad I
used the HS for hand solder, because it is not truly the M for maximum
 and would conflict with a  true JEDEC M

my QFP with pad hand solder has a pin placed in the center of the pad
to allow for applying heat through the via and to solder the back of
the part.
