11、 Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing 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. UNLEADED SOLDER Boards requi

12、ring 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 following characteristics. Unleaded

13、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 C . Caution: The printed pattern (cop

14、per foil) may peel away if the 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 o

15、nly unleaded solder but unleaded 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. For use in your house: For the supplied battery charging stand, use the AC power adaptor supplied with this re

29、arged electrostatic 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 E

30、MISSION CHECK Never 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 ha

31、ndling it, perform 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

32、power supplied to the set, re- moving the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S803 on MAIN board) with a tape in advance. Handle the FLEXIBLE board (over write head) with care, as it has been soldered directly to the MAIN board
