SERVICING NOTES

UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
3
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
5
: LEAD FREE MARK
5
Unleaded solder has the following characteristics.
6
• Unleaded solder melts at a temperature about 40 °C higher
6
than ordinary solder.
7
Ordinary soldering irons can be used but the iron tip has to be
7
applied to the solder joint for a slightly longer time.
8
Soldering irons using a temperature regulator should be set to
8
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
9
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 OF REPLACING THE IC2022 ON THE DIGITAL
BOARD
IC2022 on the DIGITAL board cannot exchange with single. When
this part on the DIGITAL board is damaged, exchange the entire
mounted board.
NOTE OF REPLACING THE IC3506 AND IC3508 ON
THE HDMI BOARD
IC3506 and IC3508 on the HDMI board cannot exchange with sin-
gle. When these parts on the HDMI board are damaged, exchange
the entire mounted board.
NOTE OF REPLACING THE IC5021 ON THE DSP
BOARD
IC5021 on the DSP board cannot exchange with single. When this
part on the DSP board is damaged, exchange the entire mounted
board.
