Solder Flux 559 560 223No Clean Soldering Flux Paste Lead Free Rosin Flux Tacky Soldering Flux Soldering Liquid Flux for Electro

Product description:Good quality environment-friendly soldering paste is similar to butter paste in appearance, with high bonding strength, neutral PH value, good insulation, and smooth welding surface. It is suitable for soldering of precision electronic chips such as mobile phone PC boards.Removal of oxide film: in essence, the substance in rosin undergoes a reduction reaction to remove the oxide filmOxidation prevention: after melting, it floats on the surface of solder to form an isolation layer, thus preventing oxidation of weldingReduce surface tension: increase soldering fluidity, which is helpful for soldering wet weldmentsProduct specification:Gross weight: 30g/50g/70g/100g(Weight includes packaging),10ccIngredients: RosinPaste: yellowShelf life: 12 months in the shadeApplicable to: Chip PCB motherboard solderingPackage contents:1 * Soldering aidNote: The weight may have a few grams of error, please understand if it is not very accurate.Different batches of plasters have different colors, and the actual products shall prevail.
