S

9、uch components commonlyare called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and somefield effect transistors and semiconductor “chip” components. The following techniques should be used to helpreduce the incidence of component damage caused by s

10、tatic electricity.1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off anyelectrostatic charge on your body by touching a known earth ground. Alternatively obtain and wear a commerciallyavailable discharging wrist strap device, which should be remo

11、ved for potential shock reasons prior to applyingpower to the unit under test.2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surfacesuch as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.3. Use only a grounded

12、-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” cangenerate electrical charges sufficient to damage ES devices,5. Do not use freon-propelled chemicals. These can generate electrical cha

13、nge sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately before you are ready toinstall it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam,aluminum foil or comparable conductive m

14、aterial.)7. Immediately before removing the protective material from the leads of a replacement ES device, touch theprotective material to the chassis or circuit assembly into which the device will be installed.CAUTION : Be sure no power is applied to the chassis or circuit, and observe all other sa

15、fety precautions.8. Minimize bodily motions when handling unpacked replacement ES devices. (Otherwise harmless motion such asthe brushing together or your clothes fabric or the lifting of your foot from a carpeted floor can generate staticelectricity sufficient to damage an ES device.)PRODUCT SAFETY

16、 NOTICEEach precaution in this manual should be followed during servicing.Components identified with the IEC symbol the parts list are of special significance to safety. Whenreplacing a component identified with , use only the replacement parts designated, or parts with thesame ratings or resistance

17、, wattage or voltage that are designated in the parts list in this manual.Leakage-current or resistance measurements must be made to determine that exposed parts are acceptablyinsulated from the supply circuit before returning the product to the customer. 3AVR100 / AVR2007 AVR100 / AVR2005 FRONT-PAN
