F: fiducial
# "Generic" simple QFN
F: qfn
#
# The information for these packages comes from various sources:
#
# - the C8051F326 data sheet, for the QFN28 footprint (N: mcu)
# - the AT86F326 data sheet, for the QFN32 package dimensions (N: txrx)
# - Atmel's general recommendations for QFN land patterns (N: atmel-qfn)
# - NXP's SOT617-1 and SOT617-3, for package and land pattern:
# http://www.nxp.com/package/SOT617-1.html
# http://www.nxp.com/package/SOT617-3.html
#
# Solder paste:
#
# Footprint Center pad Closest NXP (with complete land pattern)
# QFN28-Atmel 2.4 mm for further study
# QFN28-SiLabs 3.3 mm use SiLab's specification
# QFN32-VHHD-2 3.7 mm between SOT818-1 and SOT788-1
# QFN32-VHHD-6 3.4 mm SOT818-1
#
# From NXP:
#
# Package Pad Paste zone Islands Isl. size Isl. gap
# SiLabs 3.25 3.1 3 x 3 0.9
# SOT818-1 3.4 1.75 2 x 2 0.75 0.25
# SOT788-1 4.0 2.4 3 x 3 0.6 0.3
#
# NXP rules (AN10365):
# - paste zone = 35% of pad area
# - paste coverge = 20% of pad area
#
# Our parameters:
#
# Package Pad Paste zone Islands Isl. size Isl. gap Zone Coverage
# QFN32-VHHD-2 3.7 2.15 3 x 3 0.55 0.25 34% 20%
# QFN32-VHHD-6 3.4 1.95 2 x 2 0.75 0.45 33% 19%

# Known bugs:

# - really ought to merge all the various QFN definitions (we have more
# over at gta02-core) into a single QFN file with a big mean table of
# everything
