The solder wire of this type of flux has good wettability and transparent residue. This is a RoHS-compliant solder wire.* US Patent Number: 5,527,628† Specification for halogen-free requirements according to standards IPC 4101B, IEC 61249-2-21 and JPCA-ES01The composition of EM # 79-315W * lead-free tin wire is strictly controlled in the following LF-315specifications:AppearanceThe appearance of AltoLead's lead-free solder wire is silver-gray, the standard diameter is 0.20-2.40mm (± 0.05mm), 2.50mm 3.50mm (± 0.10mm), 3.60mm-4.50mm (± 0.20mm), ≥4.60 mm (± 0.30mm).CleanFlux residues must be removed, which can affect soldering reliability. Flux residues can be removed with water. Deionized water is recommended for final cleaning to ensure that all residues are removed.operatingEM # 79-315W * is suitable for any hand soldering application. EM # 17-315W is ideal for welding metals such as brass, nickel and severe copper oxide. When soldering, the soldering iron head is suitable for temperature control between 350-430oC, and the angle of the soldering iron head is 45-60 o (vertical working surface) is the best. ironThe head should be in contact with the component leads and the PCB pad surface.packageLead-free solder wire is 0.5kg or 1kg per roll, 10kg per box. The outside of the box is marked with a traceable production lot number, manufacturer name, alloy composition, weight, etc.ShipEach batch of products shipped has a corresponding analysis certificate, which proves the alloy composition and related data of the product.Storage and shelf lifeELECTROLOYEM # 79-315W * Lead-free tin wire has a shelf life of 6 months from the date of production. This product should be stored in a dry and non-corrosive environment. Minimize the oxidation of the tin wire to ensure that the package is not damaged and the tin wire is not exposed to dust and other substances.Health and safetyFor safety and health issues, please refer to the Safety Data Sheet / Material Safety Data Sheet.Core flux characteristicsCharacteristicEM#17EM#26EM#53HDEM#65EM#23NEM#75EM#79Flux typeWater-solubleNo CleanNo CleanNo CleanNo CleanHalogen FreeHalogen FreeLevel Type * 1ORH1ROL1ROL1ROL1ROL0ROL0ROL0Halide content (%)≤ 2.000≤ 0.100≤ 0.440≤ 0.4400≤ 0.080Corrosion testNAPassPassPassPassPassPassSurface Insulation Resistance * 2≥ 1 x 109Ω≥ 1 x 109Ω≥ 1 x 109Ω≥ 1 x 109Ω≥ 1 x 1011Ω≥ 1 x 1010Ω≥ 1 x 1010ΩDiffusivity (%)≥ 85≥ 82≥ 83≥ 83≥ 80≥ 80≥ 80* 1 Grade Type (Halide Composition in Rosin Flux) based on J-STD-004: ROL0 = 0.0%, ROL1 = <0.5%* 2 Surface Insulation Resistance: Test Conditions: 85 ± 2 ° C, 85 ± 2%; Condition Deviation: + 50V: Measurement Deviation: + 100V * 1 Grading Type (Halide Composition in Rosin Flux) based on J-STD-004: ROL0 = 0.0%, ROL1 = <0.5%* 3 Halogen-free definition according to IPC 4101B, IEC 61249-2-21 and JPCA-ES01.Cored flux typeFlux TypeCharacteristicClassificationEM # 17(WSF)Highly active, washable, suitable for repairing through holes, mixing and surface mount.When welding metals that are difficult to weld, such as brass, nickel, and heavily oxidized copper, it is more effective than rosin flux.ORH1EM#26Transparent, very residue-free, suitable for economical, hands-free manual soldering processes, is the best choice for electronics assemblers who require no-clean and clean residue.ROL1EM#53HDMoisturizing fast, strong activity, suitable for consumer electronics assembly industry, under normal conditions of use flux residue corrosion, non-conductive, most consumer electronics assembly industry users disposable leaveROL1EM#65Moisturizing fast, strong activity, suitable for consumer electronics assembly industry, under normal conditions of use flux residue corrosion, non-conductive, most consumer electronics assembly industry users disposable leaveROL1EM#23N Halide-free, minimal residue, transparent, suitable for hands-free hand welding assembly.Show rapid wetting properties.Disposable, low-residue properties make it the widest and most popular choice.Suitable for a variety of different alloys.ROL0EM#75(HF)Halogen-free, clear residue, suitable for hands-free hand welding assembly.Show good wetting properties.Disposable, low-residue properties make it the widest and most popular choice.ROL0EM#79(HF)Halogen-free, clear residue, suitable for hands-free hand welding assembly.Show good wetting properties.Disposable, low-residue properties make it the widest and most popular choice.ROL0* 3 Halogen-free definition according to IPC 4101B, IEC 61249-2-21 and JPCA-ES01.
