Electrostatic sensitive devices

Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These components can be damaged or destroyed if they are not handled correctly. To protect
equipment against damage, follow the instructions given below.
● Only touch electronic modules if you absolutely have to work on them.
● The body of the person concerned must have been electrostatically discharged and
● Electronic modules should not be brought into contact with electrically insulating materials,
● Always place electrostatic sensitive devices on conductive bases.
● Always pack, store and transport electronic modules or components in conductive
The necessary ESD protective measures for electrostatic sensitive devices are illustrated once
again in the following drawings:

d = ESD overall
Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charges can
occur, for example as a result of mechanical friction, flowing air that contains particles - or
persons that are not appropriately grounded, e.g. when carrying out maintenance or cleaning
work.
