leaving the workbench.
When transferring a sensitive device from an installed Teledyne ML analyzer to an Anti-
ESD workbench or back:
1. Follow the instructions listed above for working at the instrument rack
and workstation.
2. Never carry the component or assembly without placing it in an anti-ESD
bag or bin.
3. Before using the bag or container allow any surface charges on it to
dissipate:
If you are at the instrument rack, hold the bag in one hand while your
•
wrist strap is connected to a ground point.
If you are at an anti-ESD workbench, lay the container down on the
•
conductive work surface.
In either case wait several seconds.
•
4. Place the item in the container.
5. Seal the container. If using a bag, fold the end over and fastening it with
anti-ESD tape.
Folding the open end over isolates the component(s) inside from the
•
effects of static fields.
Leaving the bag open or simply stapling it shut without folding it
•
closed prevents the bag from forming a complete protective envelope
around the device.
6. Once you have arrived at your destination, allow any surface charges
that may have built up on the bag or bin during travel to dissipate:
• Connect your wrist strap to ground.
If you are at the instrument rack, hold the bag in one hand while your
•
wrist strap is connected to a ground point.
• If you are at a anti-ESD work bench, lay the container down on the
conductive work surface
• In either case wait several seconds
7. Open the container.
Packing materials such as bubble pack and Styrofoam pellets are extremely efficient
generators of static electric charges. To prevent damage from ESD, Teledyne ML ships
all electronic components and assemblies in properly sealed anti-ESD containers.
Static charges will build up on the outer surface of the anti-ESD container during
shipping as the packing materials vibrate and rub against each other. To prevent these
