# ThanX to Johan Andersson (johan@homemail.com), modified by Thomas Nau
# the definition of a plcc package
# modified for correct pad numbering by Holm Tiffe
#
# modified 11-Dec-1999 Larry Doolittle <LRDoolittle@lbl.gov>
# to shorten the pads by 10 mils; PUSHOUT=5 PUSHIN=40
#
# modified 22-Dec-1999 Larry Doolittle <LRDoolittle@lbl.gov>
# put back the 10 mils on the outside; PUSHOUT=5, PUSHIN=50
#
# One last tweak 12-Jan-2000 LRD, now that the shop complained I
# didn't leave them any room to solder (looks like the 22-Dec
# change was backwards);  PUSHOUT=20, PUSHIN=40

# the definition of a plcc package with through-hole socket

# for example, Assmann A-CCS##-{Z,G} series

# mil-max specifies 0.035" drill hole and 0.062" pad.
# Assman says 0.0315" hole.  Also the mil-max outside
# dimensions are ever so slightly larger than Assmann so
# use those.  See for example
