This is a RoHS-compliant tin rod that meets and fulfills international requirements.Chemical composition of the alloyThe composition of Altolite's LF-302B lead-free tin rod is strictly controlled to the following specifications:Actual appearanceThe shape of LF-302B shows a bright appearance and uniform silver. Brand and alloy numbers are engraved on each welding rod. The weight of each welding rod is approximately 700 to 900 grams. Its physical size is approximately 330mm X 20mm X 13mm.packageEvery 20 kg of LF-302B lead-free solder rods are packed in "green" cardboard boxes. The packaging of each box contains the following information:ManufacturerGrade3. Product number / type4. Lot number5. Weight per boxDeliveryEach shipment must be accompanied by a test certificate for each batch. This certificate is used to indicate the content of each element based on LF-302 product specifications.Storage and shelf lifeIf handled properly, LF-302B lead-free solder rods can have an indefinite shelf life. This product should be stored in a dry and non-corrosive environment.To minimize further oxidation, please ensure that the packaging is not damaged.The surface of the solder loses its light and shows a pale yellow shadow. This is a superficial phenomenon and does not impair the function and performance of the product in any way.Health and safetyFor safety and health issues, please refer to the Material Safety Data Sheet.General Specifications Other ProductsLow temperature range:AlloynumberAlloycompositionSolidustemperature (° C)Liquidus temperature (° C)DescriptionFeatureApplicationLF-302Sn42/Bi58138EutecticSimple binary alloy.For special continuous soldering operation.Reasonable shear strength and fatigue resistanceCan be used for temperature-sensitive parts and LED welding operations.Can be used for multi-step welding and fuse-like fuses operations can also be used for nozzle and exhaust valve operations.LF-329Sn42/Bi57/Ag1138EutecticLow eutectic temperature.The addition of silver enhances its mechanical properties, with excellent resistance to thermal fatigueLF-323Sn64/Bi35/Ag1170190Simple binary alloy.For special continuous soldering operation.Excellent mechanical properties and thermal fatigue performanceMedium temperature range:AlloynumberAlloycompositionSolidus temperatureLiquidus temperatureDescriptionFeatureApplicationLF-303Sn99.3/Cu0.7227EutecticMedium temperature alloy.Suitable for dip soldering and wave soldering.Excellent mechanical properties, thermal fatigue resistance and excellent electrical conductivity.Suitable for dip soldering, and wave soldering.LF-305Sn96.5/Ag3.5221EutecticMedium temperature alloy.Simple binary alloy.SAC filled alloy.Excellent solder joint strength and excellent thermal fatigue properties.Suitable for BGA / CSP parts, high-voltage instrument chip welding.LF-307*Sn96.5/Ag3.0/Cu0.5217219Medium temperature alloy.Popular SAC alloy for wave soldering.Excellent mechanical properties and thermal fatigue performance.Low melting point.Suitable for dip soldering and wave soldering.LF-307HD*Sn96.5/Ag3.0/Cu0.5217219Medium temperature range alloy, high temperature dip weldingGood mechanical properties, good electrical conductivity.Cost-competitive.Low melting point.Low residue.High temperature dip weldingLF-315*Sn99/Ag0.3/Cu0.7216228Medium temperature alloy.Excellent mechanical properties and resistanceThermal fatigue performanceLow-cost SAC alloy, suitable for general dip soldering and wave soldering.LF-315HD *Sn99/Ag0.3/Cu0.7216228Medium temperature range alloy, high temperature dip weldingLF- 315X*Sn99/Ag0.3/Cu0.7+Bi216228Medium temperature alloy.LF- 318Sn98.5/Ag1.0/Cu0.5216228SN100C **Sn99.3/Cu0.6/Ni+Ge227EutecticMedium temperature alloy.Popular Sn / Cu / Ni and alloys for dip and wave soldering.Excellent mechanical properties, bright and smooth solder joints.Excellent through-hole soldering performance.Suitable for dip soldering and wave solderingSN100CL **Sn99.3/Cu0.6/Ni+Ge227EutecticMedium temperature alloy.Popular hot air leveling of the popular Sn / Cu / Ni and alloys.Suitable for hot air leveling welding
