2 Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconducto r (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ESdevices are integrated circuits and some field-effect transistors and semiconducto r "chip" components. The following techniques should be used to help reduce the inciden ce of component damage caused by electrostatic discharge (ESD). 1. Immediately before handlin g any semiconducto r component or semiconducto r-equipped assembly, drain off any ESD on your body by touchin g a known earth ground. Alternatively, obtain andwear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applyin g power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conduc tive surface such as aluminum foil, to prevent electrostatic charge buildup or exposu re of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsold er 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 sufficie nt to damage ES devices. 5. Do not use freon-propelle d chemicals. These can generate electrical charges sufficie nt 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 conduc tive foam, aluminum foil or comparable conduc tive 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 installe d. Caution: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handlin g unpack aged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficie nt to damage an ES device). 3 DLS6
