Electrostatic Discharge Control
10. Neutralize charges on all ESD packaged items by placing the packages on a grounded work surface
prior to opening them.
11. Watch for ESD markings and symbols on packaging or parts.
12. Watch for ESD markings on equipment covers and cabinets.
Materials Receiving and Parts Storage
Personnel involved in receiving and storing of parts must observe the following procedures:
1. Watch for symbols and caution markings that identify ESDS items.
2. Perform quantity counts of ESDS items without opening final protective packaging. If counts can not
be verified without opening, counts must be performed in an ESD protected area.
3. Carry ESDS items to and from storage areas in protective packaging.
4.
Ensure that all packages containing ESDS items being returned to storage are properly marked with
ESD symbols and caution notices.
Maintenance Of ESDS Components
Cleaning
WARNING
Ethyl Alcohol is flammable and toxic to eyes, skin, and respiratory tract. Avoid
skin and eye contact. Good general ventilation is normally adequate. Keep away
from open flames or other sources of ignition..
Personnel performing maintenance on ESDS components must observe the following procedures:
•
Exterior surfaces of equipment containing ESD sensitive components may be cleaned in accordance
with their respective technical documentation.
•
Printed circuit assemblies, components, connectors, and pins will be cleaned with denatured ethyl
alcohol and a camel hairbrush.
Caution:
Camel hairbrushes must be wet with ethyl alcohol when cleaning ESD devices. Do
not use a dry brush.
Compressed air sources and vacuum cleaners should be used to clean ESD sensitive item enclosures only
after all ESD sensitive items have been removed from the enclosure, or if the nozzle of the air source or
vacuum cleaner is properly grounded.
Removal, Repair, and Installation
Electrostatic charges can build up on ESDS components while they are being transported and during
maintenance. If an electrostatic charge is discharged onto the component connectors, internal circuits may
be damaged. To prevent this, the following procedures must be followed:
1. Insure that conductive covers/caps are installed on all exposed terminals and connectors.
2. Insure that the host unit is properly grounded.
3. Prior to disconnecting cable connectors, touch the unit’s case with your hand to equalize electrostatic
potentials.
4. Disconnect and remove the component.
5. Install the replacement component.
6. Remove the conductive covers/caps and install them on the removed component.
