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 grounded immediately before any electronic modules are
touched.
• Electronic modules should not be brought into contact with electrically
insulating materials, such as:
– Plastic film
– Plastic parts
– Insulating table supports
– Clothing made of synthetic fibers
• Always place electrostatic sensitive devices on conductive bases.
• Always pack, store and transport electronic modules or components in
conductive packaging, such as:
– Metallized plastic or metal containers
– Conductive foam material
– Domestic aluminum foil
The necessary ESD protective measures for electrostatic sensitive devices are
illustrated once again in the following drawings:
a = conductive floor surface
