6. Disconnecting your wrist strap is always the last action taken before leaving the workbench.
12.4.2.3. Transferring Components from Rack to Bench and Back
When transferring a sensitive device from an installed Teledyne Instruments 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.
12.4.2.4. Opening Shipments from Teledyne Instruments Customer Service.
Packing materials such as bubble pack and Styrofoam pellets are extremely efficient generators of static electric
charges. To prevent damage from ESD, Teledyne Instruments 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 static charges from damaging the components or
assemblies being shipped make sure that you always unpack shipments from Teledyne Instruments Customer
Service by:
1. Opening the outer shipping box away from the anti-ESD work area.
2. Carry the still sealed ant-ESD bag, tube or bin to the anti-ESD work area.
3. Follow steps 6 and 7 of Section 12.4.2.3 above when opening the anti-ESD container at the work station.
