SERVICING NOTES
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

(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 about 40 °C higher
• 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.
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
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 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 unleaded solder but unleaded solder may
also be added to ordinary solder.

NOTE THE PARTS ON THE EACH BOARDS REPAIR-
ING (SA-WMS55)
When the IC7 on the MAIN board is damaged, exchange this part.
When the mount parts other than IC7 on the MAIN board are
damaged, exchange the ASSY parts including complete mounted
board.
Printed wiring board and schematic diagram have been described
to this service manual is for the reference.
Refer to EXPLODED VIEWS (page 8) for part No. of the IC7.

NOTE THE IC7 ON THE MAIN BOARD REPLACING
(SA-WMS55)
When the IC7 on the MAIN board is replaced, it is necessary to
spread grease between the IC7 and INSULATION SHEET and be-
tween the heat sink and INSULATION SHEET.
Spread grease referring to the fi gure below.
