3.3.8
Rework
Rework is not recommended.
Never attempt a rework on the module itself; for example, replacing individual components. Such actions
immediately terminate the warranty.
3.3.9
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 modules and it is important to prevent them from flowing into
the module. The RF shields do not provide protection for the module from coating liquids with low viscosity,
therefore care is required while applying the coating.
Conformal coating of the module will void the warranty
3.3.10
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 modules before implementing this in the production.
Casting will void the warranty.
3.3.11
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 gives no warranty for damages to the modules caused by soldering metal cables or any other forms
of metal strips directly onto the EMI covers.
3.3.12
Use of ultrasonic processes
The short range modules contain components that are sensitive to ultrasonic waves. Use of any ultrasonic
processes (cleaning, welding and son) may cause damage to the module.
u-blox gives no warranty against damages to the modules caused by any ultrasonic processes.
