2.1 Prevention of Electrostatic Discharge (ESD) to
Electrostatically
Sensitive (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 feld-effect transistors and semiconductor "chip"
components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge
(ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by
touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be
removed for 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.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an antistatic solder removal device. Some solder removal devices not classifed as "antistatic (ESD protected)" can generate
electrical charge suffcient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges suffcient to damage ES devices.
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).
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.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
of your clothes fabric or the lifting of your foot from a carpeted foor can generate static electricity (ESD) suffcient to damage an ES
device).
