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 s miconductor “chip” components.

The techniques outlined below should be followed to h elp 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 comp onent or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touchin g 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 wit h ESDs, place the assembly on a conductive surface, such as aluminum or copper foil, or conductive foa m, to prevent electrostatic charge buildup in the vicinity of the assembly.

3.Use only a grounded tip soldering iron to solder or d esolder ESDs.

4. Use only an “anti-static” solder removal device. So e solder removal devices not classified as “anti- static” can generate electrical charges sufficient to damage ESDs.

5.Do not use Freon-propelled chemicals. When spray ed, 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 shortin g 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 unpackage d replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting on e’s foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.
