Basic protective measures against electrostatic discharge

Ensure sufficient grounding
Make sure all persons, workplaces and packaging are sufficiently grounded when ESD
components are being handled. This prevents electrostatic charging.
Avoid direct contact
You should only touch ESD components if this is 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.
