Electrostatically Sensitive (ES) Devices
1-3-7. Ordering Spare Parts
1. Immediately before handling any semiconductor component or semiconductor-
equipped assembly, drain off any electrostatic charge on your body by touching a known
earth ground. Alternatively, obtain and wear a commercially available discharging wrist
strap device, which should be removed to prevent potential shock reasons prior to applying
power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly
on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or
exposure of the assembly.

to damage ES devices.
7. Immediately before removing the protective material from the leads of a replacement
ES device, 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.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
Some semiconductor (solid-state) devices can be damaged easily by static electricity.
Such components commonly are called Electrostatically Sensitive (ES) Devices.
Examples of typical ES devices are integrated circuits and some field-effect transistors
and semiconductor "chip" components. The following techniques should be used to help
reduce the ncidence of component damage caused by static by static electricity.
4. Use only an anti-static type solder removal device. Some solder removal devices not

6. Do not remove a replacement ES device from its protective package until immediately
before you are ready to install it.
(Most replacement ES devices are packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparable conductive material).
8. Minimize bodily motions when handling unpackaged replacement ES devices.
(Otherwise harmless motion such as the brushing together of your clothes fabric or the
