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