Sn99.3Cu0.7 Copper Tin Lead Free Solder Wire
Product Description
Lead-Free Sn0.7Cu is composed of 99.3% tin, and 0.7% copper. It is desirable for use in common metal equipment, copper tubes, and copper plates. This product is a conventional type of environmentally-friendly solder by adoption of lead-free soldering technology.
Activated Rosin Flux for cored solder wire was developed for lead-free applications to enable soldering of most common metals.
Our company has obtained Reach certificate and RoHS certificate for lead-free type products, as well SGS certificate. All Sn99.3Cu0.7 lead-free solder wires made by our company can reach the EU RoHS standards.
Application
The Sn0.7Cu solder wire can be used for the soldering of the precise computer chips, mobile phone chips, LED, printed circuit board (PCB), and a variety of high-precision electronic circuit boards, among others. Meanwhile, it is suitable for the restoration of mini-sized electronic equipment.

Features
1.High Electrical Resistivity and Electrical Conductivity
Due to the addition of copper, solder wire allows the electronic components to produce relatively high electrical resistivity during the soldering process.
2.Appropriate activated rosin flux provides distinguished soldering effect, fast soldering speed, as well as extremely good fluidness.
3.High Melting Point
With high melting point, our product is ideal for the soldering of electronic equipment at high temperature. A combination of tin and copper allows this environmentally-friendly lead free solder wire to have high melting point.
4.The activated rosin flux in this product can offer superior fluxing effect.
