GENERAL INFORMATION
INFORMATION ON PREVENTING DAMAGE TO ELECTRONIC COMPONENTS DUE TO
ELECTROSTATIC DISCHARGE - AH54.00-P-0001-01A
All models
Electrostatic charge
Every contact and each physical separation of materials or any movement of solid substances, fluids or
particulate loaded gases can generate electrostatic charges. Plastics generally produce the highest
electrostatic charge.
We come across electrostatic charge or discharge in lots of everyday situations, e.g. with:
Combs
l
Walking on carpets or plastic floors
l
Putting on and removing textiles made with synthetic fiber
l
Disembarking from the vehicle
l
Contact between various electrostatically chargeable packaging materials in shelves or in the transport
l
container
The following electrostatic discharge (E lectro S tatic D ischarge (ESD)) can be so strong that a small
electric shock is detected. Even the smallest discharges which people cannot detect can cause lasting
damage to electronic components and control units.
Effects and consequences of ESD
Electronic components and control units are very sensitive to ESD. The damage is often not immediately
obvious, but becomes apparent some time later. In order to avoid failures and damage due to ESD in vehicle
electronics, various procedures and safety precautions must be taken into account and followed.
Risks of damage occur during transport, handling, testing, removal and installation of electronic components
in production as well as during repair work.
The following electronic components listed as an example can be damaged by ESD:
Airbag components
l
Control units, in particular their bus connections (Control Area Network (data bus/CAN bus) (CAN),
l
local interconnect network (LIN) etc.)
Sensors
l
Mechatronic components (actuators etc.)
l
Antenna amplifier
l
Receivers and displays (Radio, TV, GPS, telephone etc.)
