ESD guideline
What does ESD mean?
All electronic modules are equipped with large-scale integrated ICs or components. Due to
their design, these electronic components are highly sensitive to overvoltage and thus to the
discharge of static electricity. Such electronic components are labeled as Electrostatic
Sensitive Device.
Short description
The following abbreviations are commonly used for electrostatic sensitive devices:
●
EGB – Elektrostatisch Gefährdete Bauteile/Baugruppen (Germany)
●
ESD – Electrostatic Sensitive Device (internationally recognized term)
Electrostatic charge
CAUTION
Electrostatic charge
ESDs may be destroyed by voltages far below the level perceived by human beings.
Voltages of this kind develop when a component or an assembly is touched by a person
who is not grounded against static electricity. Usually, it is unlikely that damage to an ESD
as a result of overvoltage is detected immediately but may become apparent only after a
longer period of operation.
Avoid electrostatic charge to your body before you touch the ESD.
