20、omponent. Notice that the minus side of a tantalum capacitor may be dam-aged by heat.Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C duringrepairing. Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times). Be careful not to

21、 apply force on the conductor when soldering orunsoldering.SAFETY CHECK-OUTAfter correcting the original service problem, perform the followingsafety check before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws,and all other exposed metal parts f

22、or AC leakage.Check leakage as described below.LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microamperes.).Leakage current can be measured by any one of three me

23、thods.1.A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers instructions to use theseinstruments.2.A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.3.Measuring the voltage drop across a resistor by means of

24、 a VOMor battery-operated AC voltmeter. The “limit” indication is 0.75V, so analog meters must have an accurate low-voltage scale.The Simpson 250 and Sanwa SH-63Trd are examples of apassive VOM that is suitable. Nearly all battery operated digitalmultimeters that have a 2 V AC range are suitable. (S

25、ee Fig. A)This appliance is classified as a CLASS 1 LASER product.The CLASS 1 LASER PRODUCT MARKING is located onthe exterior.Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.The laser diode in the optical pick-up block may suffer electrostaticbreak-dow

26、n because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and

27、 should be handled withcare.NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from t

28、he objective lens.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveforms is output three times.UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contai

29、ns no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size): LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher thanordinary solder.Ordinary soldering irons can be us

30、ed but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 C .Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful! Strong viscosityUnleaded so

31、lder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc. Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.NOTES ON HANDLING THE OPTICAL PICK-UP
