10.4.2.3. Transferring Components from Rack to Bench and Back
When transferring a sensitive device from an installed Teledyne API instrument 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.
10.4.2.4. Opening Shipments from Teledyne API
Packing materials such as bubble pack and Styrofoam pellets are extremely efficient
generators of static electric charges. To prevent damage from ESD, Teledyne API ships
all electronic components and assemblies in properly sealed ant-ESD containers.
1. 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 API as follows:
2. Open the outer shipping box away from the anti-ESD work area.
3. Carry the still sealed ant-ESD bag, tube or bin to the anti-ESD work area.
4. Follow steps 6 and 7 of Section 10.4.2.3 above when opening the anti-ESD
contai
ner at the wo
rk station.
5. Reserve the anti-ESD container or bag to use when packing electronic components
or assemblies to be returned to Teledyne API.
