PCB DESIGN CHECK LIST
Good 12-bit layout techniques are not difficult to master
as long as a few guidelines are considered.

Check device placement versus connectors.
Make sure that high speed devices and digital
devices are closest to the connector.
Always have at least one ground plane in the cir-
cuit.
Make power traces wider than other traces on
the board.
Review current return paths and look for possi-
ble noise sources on ground connects. This is
done by determining the current density at all
points of the ground plane and the amount of
possible noise present.
By-pass all devices properly. Place the capaci-
tors as close to the power pins of the device as
possible.
Keep all traces as short as possible.
Follow all high impedance traces looking for
possible capacitive coupling problems from
trace to trace.
