Notes on chip component replacement
•  Never reuse a disconnected chip component.
•  Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

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)

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 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  IC1131  ON  THE  DIGITAL  
AB  BOARD
IC1131 on the DIGITAL AB board cannot exchange with single. 
When IC1131 on the DIGITAL AB board is damaged, exchange 
the entire mounted board.

NOTE  OF  REPLACING  THE  IC3511  AND  IC3513  ON  
THE  HDMI  BOARD
IC3511 and IC3513 on the HDMI board cannot exchange with sin-
gle. When IC3511 and IC3513 on the HDMI board are damaged, 
exchange the entire mounted board.
