7.2 Moisture Sensitivity Levels

⚠ SARA-R4 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 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 user 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 series

system integration manual [2]).

⚠ Failure to observe these recommendations can result in severe damage to the device!

7.4 ESD precautions

⚠ SARA-R4 series modules contain highly sensitive electronic circuitry and are Electrostatic

Sensitive Devices (ESD). Handling SARA-R4 series modules without proper ESD protection may

destroy or damage them permanently.

SARA-R4 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 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 series module.

ESD precautions should be implemented on the application board where the module is mounted, as

described in the SARA-R4 series system integration manual [2].

⚠ Failure to observe these recommendations can result in severe damage to the device!
