【Wide Applications】The SMD soldering paste is suitable for various applications, including mobile phone repairs, manual surface mounting (SMT), BGA soldering, LED SMT soldering, ribbon cable soldering, capacitor and resistance soldering and much more. Whether simple circuit repairs or complex electronics assemblies, the solder flux delivers stable and reliable soldering results and protects your components and circuit boards.
High-quality materials: the solder flux is based on rosin, environmentally friendly and does not need to be cleaned. Solder paste not only guarantees excellent soldering results, but also speeds up the soldering process significantly and thus saves valuable time. Whether you are a beginner or an experienced technician, you can easily get started and achieve satisfactory results.
Efficient soldering: The soldering flux has a melting point of only 60 °C and is therefore ideal for heat-sensitive circuit boards or electronic components. The low melting point of the soldering paste allows fast melting when soldering, reduces heat damage to sensitive components, protects the circuit board and ensures reliable soldering results.
Easy to use: the flux soldering is very easy to use. Simply remove the cap, insert the needles, remove the back cover and put on the slider - you're ready to go. The precise tip of the flux soldering allows precise application to the soldering points, avoids material waste and unnecessary effort and thus makes it easier for beginners to get started.
Contents of the set: you will receive 2 tubes of flux solder, 2 sliders and 4 needles. The complete set ensures that you always have enough SMD soldering paste for various soldering work at hand. Whether for DIY projects or professional electronics projects, this kit provides you with enough material and accessories so you don't have to worry about consumables.
