TABLE OF CONTENTS
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 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.
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.
Flexible Circuit Board Repairing
  •  Keep the temperature of soldering iron around 270 °C during 
repairing.
  •  Do not touch the soldering iron on the same conductor of the 
circuit board (within 3 times).
  •  Be careful not to apply force on the conductor when soldering 
or unsoldering.
