5、he 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 integrated circuits and some field effec

Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge onyou

7、r 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 assembly equipped with ES devices, place

8、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 solder removal devices not classified as a

9、nti-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 immediately before you are ready to insta

10、ll 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, touch the protective material to thechassis

11、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 such as the brushing togetheror your clot
