The RF shields do not provide 100% protection for the module from coating liquids with low viscosity, and
therefore care is required in 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 cellular modules before implementing this in 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.
☞ Tashang gives no warranty for damages to the TOBY-L3 series 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 cellular modules contain components which are sensitive to ultrasonic waves. Use of any ultrasonic
processes (cleaning, welding etc.) may cause damage to the module.
☞ Tashang gives no warranty against damages to TOBY-L3 series modules caused by any ultrasonic
processes.
