Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during

17、 repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in h

18、azardous radiation exposure. SAFETY-RELATED COMPONENT WARNING! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.

19、UPPLEMENTS PUBLISHED BY SONY. ? ? ? ? ? ? Ver. 1.2 收音机爱好者资料库 Ra d i o Fa n s .CN 4 MZ-DH10P SECTION 1 SERVICING NOTES The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and

20、 the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is

21、concentrated so as to be focused on the 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 the objective lens. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT OPERATION CHECK

22、WHEN THE MAIN BOARD IS REMOVED In making an operation check with the MAIN board removed from the set, short the SL894 of the MAIN board with the solder before starting the operation check. Note: Be sure to remove the solder used for shortcircuit after the repaire completed. MAIN BOARD (Conductor Sid

23、e) SL894 UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the

24、 following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350

25、C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable wit

26、h ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
