2.1.
Prevention of Electrostatic Discharge (ESD) to Electrostatically
Sensitive (ES) Devices
Some sem iconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec
trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and
sem iconductor [chip] components. The following techniques should be used to help reduce the incidence of com ponent damage
caused by electrostatic discharge (ESD).
1. Immediately before handling any sem iconductor com ponent or semiconductor-equipped assembly, drain off any ESD on your
body by touching a known earth ground. Alternatively, obtain and w ear a com m ercially available discharging ESD w rist strap,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. A fter removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as alumi
num 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 anti-static solder removal device. Some solder removal devices not classified as [anti-static (ESD protected)] can
generate electrical charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient 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 compara
ble 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 ham less motion such as the brush
ing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient
to damage an ES device).
