# ThanX to Johan Andersson (johan@homemail.com), modified by Thomas Nau
# the definition of a plcc package for base code to make qfp package.
# modified for correct pad numbering by Holm Tiffe
#
# Code from plcc.inc modified by Thomas Olson to make this qfp.inc definition.
# Although in retrospec quad flat packs are more diverse than this algorithm will do.
# Many qfp are the same physical size but have more thus narrower pads.
