Settings according to
http://www.nxp.com/documents/mounting_and_soldering/AN10365.pdf

to 25 um

silk screen !)

- atusb.brd, atusb.cmp: changed 0603-M to the new 0603
- atusb.brd: updated layout for component changes
- atrf.sch: replaced the AT86RF230 with the AT86RF231
- atusb.sch, usb.sch, atrf.sch: removed TST signal

- atusb.sch, usb.sch, atrf.sch, atusb.brd: changed version to 20110104
- atusb.brd: increased RF ground zone by 150 mil in an attempt to reduce
interferences between the the antenna and the rest of the circuit
- atusb.brd: added more vias around and inside the RF ground zone
- atusb.brd: set version to 20110102
Traces leaving a pad on the side may invite solder bridges to "false pads"
exposed at the edges of the chip, with unknown consequences.
- atusb.brd: make trace from P0.0 (IRQ_RF) leave pad at the front, not
at the side
- atusb.brd: make trave from P0.7 (SCLK) leave pad at front, not at the
side
- atusb.brd: nRST may need an external pull-up to VDD. Added via to bring
nRST and VDD within reach (pull-up suggested by Joerg Reisenweber)
- atusb.brd: increased version to 20101229
- atusb.brd: increase clearance between RF clock front ground area and MCU
(ground area acted as solder trap)
- atusb.brd: route nRST_RF trace out of corner (to avoid accidental
contact)
- atusb.brd: don't route VBUS corner trace underneat chip (for general
tidiness)
- atusb.brd: bumped version to 20101219
- atusb.brd: reduced RF front ground area to avoid interconnections very
close to the chip
- atusb.brd: reduced RF power front ground area to avoid interconnections
very close to the chip
- atusb.brd: moved via next to TXRX pad 18 (GND) to make room for making
CLK trace leave the pad at its end, not at its side
- atusb.brd: bumped design date to 20101217
- usb.sch: use P0.2 as board revision ID pin
- atrf.sch: label feed line
- atusb.brd: set feed line width via design rule, not as user size
- atusb.brd: increase feed line width from 18 mil to 19 mil (it should be
58 mil, but we don't have room for more)
- atusb.brd: bumped version number to 20101202
- atusb.brd: put version number on PCB
- atusb.sch, usb.sch, atrf.sch: bumped version number to 20101202
- atusb.brd: moved traces into USB plug such that they coincide with
thermal relief
- atusb.brd: moved trace into antenna ground such that it coincides
with thermal relief
- atusb.pro: reduced edge and drawing line width from 15 mil to 5 mil
- atusb.brd: added ground zones on bottom layer

compatibility with selected part
