Precautions
3. Precautions
Follow these ESD precautions to prevent equipment damage.
1. 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. 2. Before handling a semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by using the standard Xerox ESD protection kit, which should be removed for your personal safety reasons prior to applying power to the machine. 3. After removing an electrical assembly equipped with ESDs, place the assembly on the conductive mat of the ESD kit, to prevent electrostatic charge buildup in the vicinity of the assembly. 4. Use only a grounded tip soldering iron to solder or de-solder ESDs. 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.
6.
7.
8.
9.
Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs. 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. 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. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit. Minimize bodily motions when handling unpacked 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.
