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.
Electrostatic charging
Human body not connected to surrounding electrical level may have electrostatic
charging.
The following data indicates the maximum electrostatic voltages generated when
human bodies contact specific materials. These values are compliant with IEC 801-2
specifications.
Electrostatic voltage on the operator
Basic protection measures to prevent electrostatic discharge:
Ensure excellent equipotential connection:
When holding an ESD-sensitive device, make sure your body, working area and
