APPENDIX
C. ESD Guidelines
What does ESD mean?
Virtually all present-day modules incorporate highly integrated MOS devices or
components. For technological reasons, these electronic components are very sensitive to
overvoltages and consequently therefore to electrostatic discharge:
These devices are referred to in German as Elektrostatisch Gefährdeten
Bauelemente/ Baugruppen: ºEGBº
The more frequent international name is:
ºESDº (E lectrostatic Sensitive Device)
The following symbol on plates on cabinets, mounting racks or packages draws attention to
the use of electrostatic sensitive devices and thus to the contact sensitivity of the
assemblies concerned:
ESDs
may be destroyed by voltages and energies well below the perceptionthreshold of
persons. Voltages of this kind occur as soon as a device or an assembly is touched by a
person who is not electrostatically discharged . Devices exposed to such overvoltages cannot
immediately be detected as defective in the majority of cases since faulty behavior may occur
only after a long period of operation.
Precautions against electrostatic discharge
Most plastics are capable of carrying high charges and it is therefore imperative that they be
kept away from sensitive components.
When handling electrostatic sensitive devices, make sure that persons, workplaces and
packages are properly grounded.
