6.5. ESD Protection
Static electricity occurs naturally and may damage the module. Therefore, applying proper ESD
countermeasures and handling methods is imperative. For example, wear anti-static gloves during the
development, production, assembly and testing of the module; add ESD protection components to the
ESD sensitive interfaces and points in the product design.
