E.3 Basic protective measures against electrostatic discharge
Ensure sufficient grounding
Make sure all persons, workplaces and packaging are sufficiently grounded when handling
ESD components. This prevents electrostatic charge.
Avoid direct contact
You should only touch ESD components if unavoidable (for example, during maintenance
work). Handle the modules without touching any chip pins or PCB traces. In this way, the
discharged energy can not affect the sensitive devices.
Discharge your body before you start taking any measurements on a module. Do so by
touching grounded metallic parts. Always use grounded measuring instruments.
