high quanlity tin solder wire( (Sn40Pb60) with rosin core 1:good humidity,bright beautiful,fast 2:and high isolation resistanc

Tin WIRE

 

There are two kinds of solder wire: Lead-free solder wire and Tin- lead solder wire. Rosin-cored welding wires of this series are made of the latest compound formula scaling powder with high technical content and manufactured with the most advanced automatic equipment. To cater to requirements of greater precision and more sophistication in recent years in the electronics industry, our company has developed several new high quality solder wire with diameter ranging form 0.1mm to 3.0mm.
