1. Precautions
1.3. ESD precautions
Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called
“Electrostatically Sensitive (ES) Devices” or ESDs. Examples of typical ESDs are: integrated circuits, some field effect
transistors, and semiconductor “chip” components. The techniques outlined below should be followed to help reduce the
incidence of component damage caused by static electricity.
CAUTION
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1) Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available
wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit
under test.
2) After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as
aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.
3) Use only a grounded tip soldering iron to solder or desolder ESDs.
4) 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.
5) Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.
6) Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most
replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable
conductive material.
7) Immediately before removing the protective shorting 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.
8) Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until
completely plugged or soldered into the circuit.
9) Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing together
of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.
