7.2 Shipment, storage and handling
For important information regarding shipment, storage and handling see the u-blox Package Information Guide
[3].
7.2.1 Moisture Sensitivity Levels
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required. NEO-7 modules
are rated at MSL level 4.
For MSL standard see IPC/JEDEC J-STD-020, which can be downloaded from www.jedec.org.
7.2.2 Reflow soldering
Reflow profiles are to be selected according u-blox recommendations (see MAX-7 / NEO-7 Hardware Integration
Manual [1]).
7.2.3 ESD handling precautions
NEO-7 modules are Electrostatic Sensitive Devices (ESD). Observe precautions for handling!
Failure to observe these precautions can result in severe damage to the GNSS receiver!
GNSS receivers are Electrostatic Sensitive Devices (ESD) and require special precautions when handling. Particular
care must be exercised when handling patch antennas, due to the risk of electrostatic charges. In addition to
standard ESD safety practices, the following measures should be taken into account whenever handling the
receiver:
• Unless there is a galvanic coupling between the
local GND (i.e. the work table) and the PCB GND,
then the first point of contact when handling the
PCB must always be between the local GND and
PCB GND.
• Before mounting an antenna patch, connect
ground of the device
• When handling the RF pin, do not come into
contact with any charged capacitors and be
careful when contacting materials that can
develop charges (e.g. patch antenna ~10pF, coax
cable ~50-80pF/m, soldering iron, …)
• To prevent electrostatic discharge through the RF
input, do not touch any exposed antenna area. If
there is any risk that such exposed antenna area is
touched in non ESD protected work area,
implement proper ESD protection measures in the
design.
• When soldering RF connectors and patch
antennas to the receiver’s RF pin, make sure to
use an ESD safe soldering iron (tip).
