TABLE OF CONTENTS Note: Refer to service manual supplement-1 for printed wiring board, schematic diagram and electrical parts list of PHA-1AEU. Ver. 1.1 PHA-1A/1AEU 3 SECTION 1 SERVICING NOTES UNLEADED SOLDER Boards requiring

24、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 solde

25、r 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 (copper fo

26、il) 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 fl ow) 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 u

27、nleaded solder but unleaded solder may also be added to ordinary solder. The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.
