Features of TC lead-free solder wire:
-Good electrical conductivity and heat conductivity, solder plating with high speed.
-Good wetting.
-With suitable content of rosin, it will not splash while working.
-The rosin is uniformly distributed.
-The wire are rolled equality, it doesnt knot while working.
-Minimum residue after soldering.

Kinds of lead-free solder wires available:
-No-clean solder wire
-High temperature solder wire
-Solid solder wire
-Rosin cored solder wire
-Other special solder wire(Specification as customer required)
