Electrostatic charging
Anyone who is not connected to the electrical potential of their surroundings can be
electrostatically charged.
The diagram below shows the maximum electrostatic voltage which may build up on a
person coming into contact with the materials specified in the diagram. These values
correspond to IEC 801-2 specifications.
Basic protective measures against electrostatic discharge
● Make sure the grounding is good:
When handling electrostatic sensitive devices, ensure that your body, the workplace and
packaging are grounded. In this way, you can avoid becoming electrostatically charged.
● Avoid direct contact:
As a general rule, only touch electrostatic sensitive devices when if this is unavoidable
(for example, during maintenance work). Handle the devices without touching any chip
pins or PCB traces. In this way, the discharged energy cannot reach or damage sensitive
devices. Discharge your body before taking any necessary measurements on a device.
Do so by touching grounded metallic parts. Use only grounded measuring instruments.
