Service and Maintenance
If any circuit boards or IC packages are to be stored
or transported, enclose them in conductive envelopes
and/or carriers . Remove the items from such enve-
lopes only with the above precautions; handle IC
packages without touching the contact pins .
Avoid circumstances that are likely to produce static
charges, such as wearing clothes of Synthetic mate-
rial, sitting on a plastic-covered or rubber-footed stool
(particularly while wearing wool), combing your hair,
or making extensive erasures. These circumstances
are most significant when the air is dry.
When testing static-sensitive devices, be sure dc
power is on before, during, and after application of
test signals. Be sure all pertinent voltages have been
switched off while boards or components are removed
or inserted, whether hard wired or plugged in.
The symbol shown below may appear on circuit
boards and/or schematic diagrams to call attention
to static sensitive component parts. However, the ab-
sence of such a symbol does NOT assure the absence
of static sensitive devices.
