11、(ESD) to Electrostatic Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors

12、 and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by tou

13、ching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, 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 the assembly o

14、n a conductive surface such as alumi- num foil, to prevent electrostatic charge buildup 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 “anti-stati

15、c (ESD protected)” can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are rea

16、dy to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or compara- ble conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material

17、 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 safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the br

18、ushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) suf- ficient to damage an ES device). 8 2.2.Precaution of Laser Diode Caution: This product utilizes a laser diode with the unit turned “on”, invisible laser radiation is em

19、itted from the pickup lens. Maximum output radiation power from pickup: 100 W/VDE Laser radiation from the pickup unit is safety level, but be sure the followings: 1. Do not disassemble the pickup unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on

20、the pickup unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pickup lens for a long time. 9 2.3.Service caution based on Legal restrictions 2.3.1.General description about Lead Free Solder (PbF) The lead free solder has been used i

21、n the mounting process of all electrical components on the printed circuit boards used for this equipment in considering the globally environmental conservation. The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin (Sn)

22、, silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30 degrees C (86F) more than that of the normal solder. Definition of PCB Lead Free Solder being used Service caution for repair work using Lead Free Solder (PbF) The lead free solder has to be used when re

23、pairing the equipment for which the lead free solder is used. (Definition: The letter of “PbF” is printed on the PCB using the lead free solder.) To put lead free solder, it should be well molten and mixed with the original lead free solder. Remove the remaining lead free solder on the PCB cleanly f

24、or soldering of the new IC. Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the lead free solder. Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 35030 degree

25、s C (66286F). Recommended Lead Free Solder (Service Parts Route.) The following 3 types of lead free solder are available through the service parts route. RFKZ03D01K-(0.3mm 100g Reel) RFKZ06D01K-(0.6mm 100g Reel) RFKZ10D01K-(1.0mm 100g Reel) Note * Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copp

26、er (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3% The letter of “PbF” is printed either foil side or components side on the PCB using the lead free solder. (See right figure) 10 2.4.Handling Precautions for Traverse Unit The laser diode in the optical pickup unit may break down due to static el

27、ectricity of clothes or human body. Special care must be taken avoid caution to electrostatic breakdown when servicing and handling the laser diode in the traverse unit. 2.4.1.Cautions to Be Taken in Handling the Optical Pickup Unit The laser diode in the optical pickup unit may be damaged due to el

28、ectrostatic discharge generating from clothes or human body. Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser diode. 1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise structure. 2. To prevent the lase

29、r diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed should be short-circuited with a short pin or a clip. 3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the flexible cable. 4. The antistatic FP

30、C is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexi- ble cable, cut off the antistatic FPC. Figure 1 2.4.2.Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup (laser diode) and the opt

31、ical pickup will be damaged by static electric- ity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 2.4.2.1.Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and

32、 ground the sheet. 11 2.4.2.2.Human body grounding 1. Use the anti-static wrist strap to discharge the static electricity form your body.
