Sn Ag Cu Solder
Features
1. This medium-high temp Pb free Sn-Ag-Cu solder features high purity, excellent solder ability, good wettability, strong anti-oxidization, little solder residue, little solder spatter, little smoke and smell, fast soldering speed, great thermal fatigue resistance and good fluidity.
2. We manufacture the tin silver copper alloy for medium-high temperature according to RoHS and REACH standards.
3. Solder flux is uniformly distributed in Pb free Sn-Ag-Cu solders.
4. Solder joints rarely craze and shows great reliability as well as superior mechanical performance; besides, copper corrosion is weak.
5. This tin silver copper alloy for medium-high temperature needs no cleaning.
6. It has high insulation resistance.
7. Pb free Sn-Ag-Cu solders are widely utilized in soldering temp-sensitive components, LEDs and many other electronic elements.

- Sn96.5Ag3Cu0.5 Solder Wire and Solder Bar Applied to a variety of electronic components welding in televisions, computers, polychlorinated biphenyls (PCBS), led, instruments, meters, etc.It can be manual welding and wave soldering。
- Sn95.8Ag3.5Cu0.7 Solder Solder is a general term applied to fill the weld seam welding and brazing layers of metal alloy materials. Including welding (welding wire), welding (welding rod), solder (brazing and soldering alloy) and so on. Welding solder is usually not lower than the melting temperature of the solidus of the base material, its chemical composition, mechanical, and thermal properties are relatively close to the base material, such as a variety of welding, flux-cored wire and so on.
