2.6 Components that can be destroyed by electrostatic discharge (ESD)
ESD guidelines
Material damage caused by electrostatic discharge.
Electronic components can be destroyed in the event of improper handling, transport, storage,
and shipping.
Pack the electronic components in appropriate ESD packaging; e.g. ESD foam, ESD
packaging bags and ESD transport containers.
To protect your equipment against damage, follow the instructions given below.
● Avoid physical contact with electronic components. If it is essential that you perform work on
these components, you must wear one of the following pieces of protective gear:
– Grounded ESD wrist strap
– ESD shoes or ESD shoe grounding strips if there is also an ESD floor.
● Do not place electronic components close to data terminals, monitors or televisions.
Maintain a minimum clearance to the screen (> 10 cm).
● Electronic components should not be brought into contact with electrically insulating
materials such as plastic foil, plastic parts, insulating table supports or clothing made of
synthetic fibers.
● Bring components into contact only with ESD-compliant materials, e.g. ESD tables, ESD
surfaces, ESD packaging.
● Only carry out measurements on the components if one of the following conditions is met:
– The measuring device is grounded with a protective conductor, for example.
– The measuring head of a floating measuring device has been discharged directly before
the measurement.
The necessary ESD protective measures for the entire working range for electrostatically
sensitive devices are illustrated once again in the following drawings.
Precise instructions for ESD protective measures are specified in the standard
DIN EN 61340‑5‑1.
