4.2.10 Casting
If casting is required, use viscose or another type of silicone-pottant. The OEM is strongly advised to qualify such
processes in combination with the LISA-U2 modules before implementing this in the production.
Casting will void the warranty.
4.2.11 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 LISA-U2 modules caused by soldering metal cables or any
other forms of metal strips directly onto the EMI covers.
4.2.12 Use of ultrasonic processes
LISA-U2 modules contain components which are sensitive to Ultrasonic Waves. Use of any Ultrasonic Processes
(cleaning, welding etc.) may cause damage to the module.
u-blox gives no warranty against damages to the LISA-U2 modules caused by any Ultrasonic Processes.
