Product Information
7.2.1 Moisture Sensitivity Levels
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required. The
NEO-M8U modules are rated at MSL level 4.
☞ For MSL standard see IPC/JEDEC J-STD-020, which can be downloaded from www.jedec.org.
☞ For more information regarding MSL see the u-blox Package Information Guide Error! Reference
source not found..
7.2.2 Reflow soldering
Reflow profiles are to be selected according u-blox recommendations (see the
NEO-M8U Hardware
Integration Manual
Error! Reference source not found.).
7.2.3 ESD handling precautions
⚠ NEO-M8U 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 ha
ndling 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 ~10 pF,
coax cable ~50-80 pF/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).
