Advance Information
Base boards with combined through-hole technology (THT) components and surface-mount
technology (SMT) devices require wave soldering to solder the THT components. Only a single wave
soldering process is encouraged for boards populated with modules.
Rework
We do not recommend using a hot air gun because this is an uncontrolled process and might
damage the module.
Attention : Use of a hot air gun can lead to overheating and severely damage the module.
Always avoid overheating the module.
After the module is removed, clean the pads before re-applying solder paste, placing and reflow
soldering a new module.
Attention : Never attempt a rework on the module itself, e.g. replacing individual components.
Such actions immediately terminate the warranty.
Conformal coating
Certain applications employ a conformal coating of the PCB using HumiSeal® or other related
coating products. These materials affect the HF properties of the GNSS module and it is important
to prevent them from flowing into the module. The RF shields do not provide 100% protection for the
module from coating liquids with low viscosity; therefore, care is required in applying the coating.
Conformal Coating of the module will void the warranty.
Casting
If casting is required, use viscose or another type of silicon pottant. The OEM is strongly advised to
qualify such processes in combination with the module before implementing this in the production.
Casting will void the warranty.
Grounding metal covers
Attempts to improve grounding by soldering ground cables, wick or other forms of metal strips
directly onto the EMI covers is done at the customer’s own risk. The numerous ground pins should
be sufficient to provide optimum immunity to interferences and noise.
u-blox makes no warranty for damages to the module caused by soldering metal cables or
any other forms of metal strips directly onto the EMI covers.
Use of ultrasonic processes
Some components on the module are sensitive to Ultrasonic Waves. Use of any Ultrasonic
Processes (cleaning, welding etc.) may cause damage to the GNSS Receiver.
u-blox offers no warranty against damages to the module caused by any Ultrasonic
Processes.
