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 
field-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 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 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. 

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 brushing 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).
