Notes on chip component replacement
0 Never reuse a disconnected chip component,
0 Notice that the minus side of a tantalum capacitor may be
damaged by heat.

Unleaded solder

Boards requiring use of unleaded solder are primed with the lead
free mark (LF) indicating the solder contains no leadr

(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.

0 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!

0 Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

o Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
