2.5 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
