Product: Tin Wire Product composition: Sn96.5Ag3.0Cu0.5 Product diameter: 1.0mm Product weight: 1000g Working temperature: 380-420â?? Flux content: 2.0% Product packaging: 10 rolls/box product description: Using high-purity tin raw materials to fuse electrolytic copper and pure silver, it is refined through a special process; the rosin core of the product is made of high-quality pure white transparent hydrogenated rosin with an organic acid activator independently developed by itself, and is boiled in a vacuum-tight container. Its process is particularly reliable; according to the activity of the rosin core, it is divided into three types: R type (low activity), RMA type (medium activity), and RA type (high activity). , The solder wire has the characteristics of low smoke and high insulation resistance, and it also has the dual functions of spot welding and drag welding, which enhances the versatility of the solder wire.
