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

39、 OPERATION CHECK 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 BOA

40、RD (Conductor Side) 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 Unlead

41、ed solder has the 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

42、set to about 350 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

43、, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
