8.3 ESD Guideline
Definition of ESD:
All the electronic modules are equipped with large-scale integrated ICs or assemblies.
Due to their own design, these electronic components are extremely sensitive to
over-voltage, therefore, they are extremely sensitive to any electrostatic discharge.
ESD-sensitive assemblies/modules are usually called ESD devices. This is also the
internationally universal abbreviation for these devices.
The following sign can be used to identify ESD modules:
Caution
ESD devices can be damaged by any voltage far lower than that can be felt by
human. If you do not release electrostatic charges on your body when you contact a
component of the device or carry out electrical connection for the device,
electrostatic voltage will be generated. The current of electrostatic discharge may
cause potential problem to the module. The damage may not seem serious for the
moment, but may lead to malfunction during later operation.
