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