5.5 ESD Handling
Please carefully follow the following precautions to prevent severe
damage to GPS modules.
GlobalTop GPS modules are sensitive to electrostatic discharges, and thus are Electrostatic
Sensitive Devices (ESD). Careful handling of the GPS modules and in particular to its patch
antenna (if included) and RF_IN pin, must follow the standard ESD safety practices:
Unless there is a galvanic coupling between the local GND and the PCB GND, then
the first point of contact when handling the PCB shall always be between the local
GND and PCB GND.
Before working with RF_IN pin, please make sure the GND is connected
When working with RF_IN pin, do not contact any charges capacitors or materials
that can easily develop or store charges such as patch antenna, coax cable,
soldering iron.
Please do not touch the mounted patch antenna to prevent electrostatic discharge
from the RF input
When soldering RF_IN pin, please make sure to use an ESD safe soldering iron (tip).
