SERVICING NOTES
UNLEADED SOLDER

free mark (LF) indicating the solder contains no lead.

Unleaded solder has the following characteristics.
4
•
Unleaded solder melts at a temperature about 40 °C higher
5
than ordinary solder.
6
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
9
about 350 °C.
9
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.
