5.1 ESD handling precautions

RCB-F9T contains highly sensitive electronic circuitry and is an Electrostatic Sensitive
Device (ESD). Observe precautions for handling! Failure to observe these precautions can
result in severe damage to the GNSS 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
~10 pF, coax cable ~50-80 pF/m or 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)
