5、osed parts are acceptablyinsulated from the supply circuit before retuming the product to the customer.Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are

6、 integrated circuits and some field effect transistors andsemiconductor chip components.The following techniques should be used to help reduce the incidence of component damage caused by static electricity.1. Immediately before handling any semiconductor component or semiconductor-equipped assembly,

7、 drain off any electrostatic charge onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,which should be removed for potential shock reasons prior to applying power to the unit under test.2. After removing an electrical

8、assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, toprevent electrostatic charge build-up 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 s

9、older removal devices not classified as anti-static can generate electrical chargessufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until

10、immediately before you are ready to install it. (Most replacementES 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, tou

11、ch the protective material to thechassis 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 harmless motion
