7.2 Moisture Sensitivity Levels
SARA-R4/N4 series modules are Moisture Sensitive Devices (MSD) in accordance to the
IPC/JEDEC specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required.
SARA-R4/N4 series modules are rated at MSL level 4. For more information regarding moisture
sensitivity levels, labeling, storage and drying, see the u-blox Package Information Guide [3].
For the MSL standard, see IPC/JEDEC J-STD-020 (can be downloaded from www.jedec.org).
7.3 Reflow soldering
Reflow profiles are to be selected according to u-blox recommendations (see the SARA-R4/N4 series
System Integration Manual [2]).
Failure to observe these recommendations can result in severe damage to the device!
7.4 ESD precautions
SARA-R4/N4 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling SARA-R4/N4 series modules without proper ESD protection
may destroy or damage them permanently.
SARA-R4/N4 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD
precautions typically applied to ESD sensitive components.
Table 7 details the maximum ESD ratings of the SARA-R4/N4 series modules.
Proper ESD handling and packaging procedures must be applied throughout the processing, handling
and operation of any application that incorporates the SARA-R4/N4 series module.
ESD precautions should be implemented on the application board where the module is mounted, as
described in the SARA-R4/N4 series System Integration Manual [2].
Failure to observe these recommendations can result in severe damage to the device!
