Lead-free solder wire(Ag3.5Cu0.8): Jion high anti-oxidation element, Melting, mixing, testing, molding ,bright solder Lead-free solder wire(Ag3.5Cu0.8)Alloy composition Sn95.7Ag3.5Cu0.8, good copper, tin wettability and electrical conductivity,thermal conductivity , solder joints bright, reliable ,Solder wire can  be according to the different inner core solid corewire,rosin-based flux, synthetic resin flux, water-soluble welding cores. APPLICATION Conductivity, thermal conductivity properties of excellent speed on the tin. Good wetting properties. Rosin moderate levels, the operation will not splash bombs rosin. Rosin announced uniform, tin rosin core where the situation without breaking. Winding uniform alignment will not tangle. When soldering tip less residue.
