20g-50g Lead-free No-clean High Purity Solder Wire Tin Low Melting Point Degrees Solder Wire for Electronic Repair Sn99.3cu0.7Description ：unleadedTin (Sn)： 99.7% ； Copper(Cu): 0.3%Diameter:0.6mm/0.8mm/1.0mmWeight : 20g/30g/50g (Including Roll Weight)Effective Rosin Flux Core Cleans The SurfaceDuring soldering spatter less, smoke less, smell feel relaxedGood solderability, Insulation resistance, no spattering and Non-corrosive.Suitable for Widely used in electrical, electronics and othersProduct Features Summary ：【 High quality lead-free solder wire 】Our wires are made of high quality, environmentally friendly lead-free solder,compliant and suitable for a wide range of welding tasks.【 Rosin core flux 】The rosin cored flux is built into the wire to ensure excellent welding performance. The rosin core flux is evenly distributed, so that the solder joint is firm and smooth, and the welding quality is improved.【 Wire performance 】Low melting point, good activity, high insulation resistance, fast welding speed, reduce the thermal shock caused by welding components. Reduce welding time and improve production efficiency. Suitable for fine welding operations and various electronic parts maintenance.【 Widely used 】Lead-free solder wire is widely used, suitable for electronic repair, circuit board manufacturing, lead-free welding, model making, DIY projects, etc.【 Smooth flow 】Our solder wire ensures good flow and enables a smooth welding process, improving welding accuracy and efficiency.Note:1、Size is measured manually for reference only, subject to the actual item.2、The actual color may vary slightly on different screens.3. Weight includes the weight of the coilWarm Tips ：1、When used, in order to obtain a good welding effect, the welded part must be weldable, the surface of the welded metal should be kept clean, the use of appropriate lead-free soldering iron head.2、After opening the soldering iron switch, wait until the soldering iron temperature rises to the required operating temperature before welding.3、The operator's head should be 20 CM away from the pad.4、When the soldering iron is not in use, a layer of tin should be plated on the soldering iron, and then turn off the power switch.5、The working area should be equipped with a suitable air flotation device.6. Please store the solder wire in a dry and cool environment, avoid direct sunlight and damp environment to prevent affecting the flux activity.7. During welding, please keep the working environment ventilated and use standard welding tools for operation.8. Keep the solder wire out of the reach of children to prevent accidental ingestion.
