2 SECURITY
This chapter contains important information for the safe and reliable use of the GPS receiver.
Please read this chapter carefully before starting to use this GPS receiver.
2.1 Electrostatic Discharge (ESD)
The FSA03/-LP Smart Antennas contain class 1 devices. The FSA03/-LP Smart Antennas contain
components that can be damaged or destroyed by electrostatic discharge. When handling the
modules, observe the necessary safety precautions against electrostatic discharge (ESD), in
accordance with EN 61340-5-1 and the following. The following Electrostatic Discharge (ESD)
precautions are recommended:
• Protective outer garments.
• Handle device in ESD safeguarded work area.
• Transport device in ESD shielded containers.
• Monitor and test all ESD protection equipment.
• Treat the FSA03/-LP Smart Antenna sas extremely sensitive to ESD.
2.2 Soldering method
The FSA03/-LP Smart Antennas must be soldered only manually with a soldering iron. The
soldered connection / pad design should be in accordance with IPC-A-610D - Chapter 8.2.4.
References
Customers may refer to following IPC standard for more details:
➢ IPC-A-610D chapter 8.2.4, "Castellated Terminations".
