Be careful not to apply force on the conductor when soldering or unsoldering. UNLEADED SOLDER Boards requiring use of unleaded solder ar

12、e 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 following characteristics. Unleaded solder melts at a temperature

13、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 C . Caution: The printed pattern (copper foil) may peel away if the

14、 heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unlead

15、ed solder may also be added to ordinary solder. On power sources Use house current, nikel metal hydride rechargeable battery, LR6 (SG) battery, or car battery.

ELECTRICAL PARTS LIST . 594 MZ-N10 NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic

29、 load, etc. on clothing and 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 Never

30、 look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (ABX-1R) The laser diode in the optical pick-up block may suffer electro- static break-down easily. When handling it, perform

31、soldering bridge to the laser-tap on the flexible board. Also perform mea- sures against electrostatic break-down sufficiently before the op- eration. The flexible board is easily damaged and should be handled with care. SECTION 1 SERVICING NOTES In performing the repair with the power supplied to t
