A.3 ESD Guidelines

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 good equipotential bonding:

When handling electrostatic sensitive devices, ensure that your body, the workplace and

packaging are grounded. This prevents electrostatic charge.

● Avoid direct contact:

As a general rule, only touch electrostatic sensitive devices when this is 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.
