4. If you must remove a component from the instrument, do not lay it down on a non-
ESD preventative surface where static charges may lie in wait.
5. Only disconnect your wrist strap after you have finished work and closed the case of
the analyzer.
When working on an instrument of an electronic assembly while it is resting on a anti-
ESD workbench:
1. Plug you anti-ESD wrist strap into the grounded receptacle of the work station
before touching any items on the work station and while standing at least a foot or
so away. This will allow any charges you are carrying to bleed away through the
ground connection of the workstation and prevent discharges due to field effects and
induction from occurring.
2. Pause for a second or two to allow any static charges to bleed away.
3. Only open any anti-ESD storage bins or bags containing sensitive devices or
assemblies after you have plugged your wrist strap into the workstation.
•
Lay the bag or bin on the workbench surface.
•
Before opening the container, wait several seconds for any static charges on the
outside surface of the container to be bled away by the workstation's grounded
protective mat.
4. Do not pick up tools that may be carrying static charges while also touching or
holding an ESD sensitive device.
•
Only lay tools or ESD-sensitive devices and assemblies on the conductive
surface of your workstation. Never lay them down on any non-ESD
preventative surface.
5. Place any static sensitive devices or assemblies in anti-static storage bags or bins
and close the bag or bin before unplugging your wrist strap.
6. Disconnecting your wrist strap is always the last action taken before leaving the
workbench.
When transferring a sensitive device from an installed Teledyne API 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.
