1. Precautions

1. Some semiconductor (“solid state”)devices are easily damaged by static electricity.

Such components are called Electrostatically Sensitive Devices(ESDs); Examples included

integrated circuits and Some filed-effect transistors. The following techniques will reduce

the occurrence of component damage caused by static electricity.

2. Immediately before handling any semiconductor components or assemblies, drain the electrostatic change

from your body by touching a known earth ground.

Alternatively, wear a discharging wrist-strap device. (Be sure to remove it prior to applring

Power-this is an electric shock precaution.)

3. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum

foil to prevent accumulation of electrostatic charge.

4. Do not use freon-propelled chemicals. These can generage electrical charges that damage ESDs.

5. Use only a grounded-tip soldering iron when soldering ESDs.

6. Use only anti-static solder removal device. Many solder removal devices are not rated as

“anti-static”; these can accumulate sufficient electrical charge to damage ESDs.

7. Do not remove a replacement ESDs from its protective package until you are ready to install it.

Most replacement ESDs are packaged with leads that are electrically shorted together by conductive materials.

8. Immediately before removing the protective material from the leads of a replacement ESDs,

touch the protective material to the chassis or circuit or assembly into which the device will

be installed.

9. Minimize body motions when handling unpackaged replacement ESDs. Motions such as

brusing clothes togetherer or lifting a foot from a carpeted floor can generate enough static

electricity to damage an ESDs.
