ESD guidelines

8. ESD guidelines

8.1. What is ESD?

Almost all of the SIMADYN D modules have highly-integrated devices. These devices are, from their
very nature, extremely sensitive to overvoltage conditions, and therefore also to electrostatic
discharge.
ESD
The abbreviation stands for electrostatic discharge
Modules, which use these devices have the following warning label on the component side:
Electrostatic sensitive devices can be destroyed by voltage- and energy level which lie far below the
perception levels of human beings. Voltages such as these occur when personnel touch a component
or a module without having first being previously electrostatically discharged. Components, which
have been subject to such overvoltage conditions, can generally not be immediately identified as
being faulty, as this is only manifested after a somewhat longer operating time.

8.2. Handling ESD modules

As a general rule, electronic modules should only be touched if this is absolutely necessary.
Components may only be touched if the person
is continuously grounded through an ESD bracelet, or
is wearing ESD shoes or ESD shoe grounding strips.
Before touching an electronics module, you must electrically discharge your body. This can be simply
done by touching a conductive, grounded object immediately beforehand (e. g. bare metal cabinet
parts, water pipe etc.)
Modules may not come into contact with highly insulating materials which can be statically charged.
This includes plastic foils, insulating desktops, clothing manufactured out of man-made fibers.
Modules may only be placed down on conductive surfaces (desktop with ESD surface, conductive
ESD foam rubber, ESD packing bags, ESD transport containers, cardboard- or paper surfaces).
Modules may not be brought close to data terminals, monitors or television sets.
