• Fill in all the necessary information on the applicable
documentation and place it inside the bag.
• Seal the bag.
• Place the circuit board in a suitable carton, and secure it for
shipping.
Note
Failure to follow these rules may result in unserviceable circuit
boards.
Temperature protection
If the unit must be protected against extremes of temperature,
the carton/crate must be lined on all walls, base and lid with 5
cm thick polyurethane or polystyrene foam. These units will be
identi fi ed as delicate in the applicable documentation.
The package must then be clearly marked:
Must not be transported or stored in temperatures below -5
degrees Celsius.
Other units can normally be stored in temperatures between -30°
C and +70° C, refer to the system’s technical speci fi cations for
details.
Transducers must not be stored in temperatures below -20° C
and above +60° C.
What is ESD?
Electro-Static Discharge (ESD) is the transfer of an electrostatic
charge between two bodies at different electrostatic levels,
caused either by direct contact or induction by an electrostatic
fi eld. The passing of a charge through an electronic device can
cause localised overheating, and it can also “puncture” insulating
layers within the structure of the device. This may deposit a
conductive residue of the vaporised metal on the device, and thus
create a short circuit. This may result in a catastrophic failure, or
degraded performance of the device.
ESD protection
Sensitive electronic circuit boards must be transported and
stored in protective packing bags. The circuit boards must
not be transported or stored close to strong electrostatic,
electro-magnetic or radioactive fi elds. If it is necessary to open
and touch the circuit board inside the protective bag, then the
following precautions must be taken:
