3.2.9 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 SARA-G3 series modules 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.
