Servicing Notes - Sony SA-WSIS10 Service Manual

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

SERVICING NOTES

BEGIN IT BEFORE THE REPAIR
When the SA-WSIS10 is checked, connect to HCD-IS10 (for DVD
receiver of DAV-IS10). Be sure in advance the HCD-IS10 is
prepared.
NOTE OF WHEN OUTPUT IS CONFIRMED (SS-IS10)
To connect with SA-WSIS10 and to use it, SS-IS10 is designed.
Therefore, when it connects with a usual amplifier and the audio
signal of an excessive low-frequency (800 Hz or less) is input, there
is a possibility that the speaker breaks.
When you confirm the output with large audio signal input, connect
SA-WSIS10 with SS-IS10.
