1-3 Electrostatically Sensitive Devices (ESD) Precautions
component damage caused by static electricity.
1.
Immediately before handling any
semiconductor components or assemblies,
drain the electrostatic charge from your body
by touching a known earth ground.
Alternatively, wear a discharging wrist-strap
device. Be sure to remove it prior to applying
power to avoid a shock hazard.
2.
After removing an ESD-equipped assembly,
place it on a conductive surface such as
aluminum foil to prevent accumulation of
electrostatic charge.
3.
Do not use freon-propelled chemicals. These
can generate electrical charges sufficient to
damage ESDs.
4.
Use only a grounded-tip soldering iron to
solder or desolder ESDs.
5. Use only an anti-static solder removal device.
Some solder removal devices not classified as
"anti-static" can generate electrical charges
sufficient to damage ESDs.
6. Do not remove a replacement ESD from its
protective package until you are ready to
install it. Most replacement ESDs are packaged
with leads that are electrically shorted
together by conductive foam, aluminum foil
or other conductive materials.
7.
Immediately before removing the protective
material from the leads of a replacement ESD,
touch the protective material to the chassis or
circuit assembly into which the device will be
installed.
Caution : Be sure no power is applied to the
chassis or circuit and observe all other safety
precautions.
8. Minimize body motions when handling
unpackaged replacement ESDs.
Motions such as brushing clothes together, or
lifting your foot from a carpeted floor can
generate enough static electricity to damage
an ESD.
