Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C higher than
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
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!

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.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
