Electrostatic charging
Anyone who is not connected to the electrical potential of their surroundings can be
electrostatically charged.
The figure below shows the maximum electrostatic voltage which may build up on a person
coming into contact with the materials indicated. These values correspond to IEC 801-2
specifications.

Basic protective measures against electrostatic discharge
●
Ensure correct grounding:
When handling electrostatically sensitive devices, ensure that your body, working
environment and any packaging are sufficiently grounded. This prevents electrostatic
charge.
●
Avoid direct contact:
As a general rule, only touch electrostatically sensitive devices when otherwise
unavoidable (e.g. 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.
