Handling of Electrostatic-Sensitive Devices

























































Attention

Observe Precautions for handling
Electrostatic Devices




Caution

Handling of Electrostatic-Sensitive Devices

Certain semiconductor devices used in the equipment are liable to damage due to static voltages.

Observe the following precautions when handling these devices in their unterminated state, or sub-units
containing these devices:

Persons removing sub-units from any equipment using electrostatic sensitive devices must be earthed by a
wrist strap via a 1M resistor to a suitable discharge reference point within the equipment.

Soldering irons used during any repairs must be low voltage types with earthed tips and isolated from the
Mains voltage by a double insulated transformer. Care should be taken soldering any point that may have a
charge stored.

Outer clothing worn must be unable to generate static charges.

Printed Circuit Boards (PCBs) fitted with electrostatic sensitive devices must be stored and transported in
appropriate anti-static bags/containers.
