PCB Storage and Handling Recommendations
The immersion silver finish of the PCB provides a better high-frequency performance, but is also prone to
oxidation in open environments. This oxidation causes the surface around the antenna region to blacken.
To avoid oxidation, the PCB should be stored in an ESD cover and kept at a controlled room temperature
with low humidity conditions. All ESD precautions must be taken while using and handling the EVM.
