S5-95F Guidelines for Handling Electrostatic Sensitive Devices (ESD)
D Guidelines for Handling Electrostatic Sensitive
Devices (ESD)
What is ESD?
All electronic modules are equipped with large-scale integrated ICs or components. Due to their
design, these electronic elements are very sensitive to overvoltages and thus to any electrostatic
discharge.
These Electrostatic Senstive Devices are commonly referred to by the abbreviation ESD.
Electrostatic sensitive devices are labelled with the following symbol:
!
Caution
Electrostatic sensitive devices are subject to voltages that are far below the voltage
values that can still be perceived by human beings. These voltages are present if you
touch a component or module without previously being electrostatically discharged. In
most cases, the damage caused by an overvoltage is not immediately noticeable and
results in total damage only after a prolonged period of operation.
