safety checks before releasing the set to the customer.

: LEAD FREE MARK
Unleaded solder has the following characteristics.
· Unleaded solder melts at a temperature about 40 °C higher than
ordinary solder.
AC Ordinary soldering irons can be used but the iron tip has to be
0.15 µF 1.5 k Voltmeter applied to the solder joint for a slightly longer time.
(0.75 V) 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
Earth Ground
Unleaded solder is more viscous (sticky, less prone to flow) than

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.
