Solder Flux Paste, Lead Free Rosin Soldering Paste Flux for Electronics, SMD Electrical Soldering Flux, for PCB LED IC CPU #7142 (N.W. 2.82oz/80g)
BEEYUIHF #7142 solder flux paste has a high viscosity, similar to butter in appearance, and contains rosin, which makes the solder and the soldering surface fully moisturized. The use of flux paste can greatly improve the soldering process and efficiency.
Soldering recommended soldering iron operating temperature: 210-230 ° C (410-446 ° F), when we are soldering, soldering flux will be melted than the solder material first, quickly covered in the solder surface, so that it plays a role in preventing the oxidation of the metal surface, and can be at a higher temperature and the surface of the oxidized film of the reaction of the surface of the solder, so that it is melted, to restore the pure surface of the metal.
Solder paste flux prevent re-oxidation of surfaces during soldering, reduce solder surface tension and improve soldering performance. #7142 The primary function of flux is to remove oxides from the surface of the solder and the base metal being soldered to achieve the necessary cleanliness of the metal surface.
Semi solid soldering paste flux is not easy to pour, produces a stronger connection - Flux allows the solder to bond properly over the entire target area.
Solder paste flux in paste form reduces the temperature required for soldering, minimizes thermal deformation and stress in the soldered metal, and improves the strength and reliability of the soldered joint. In order to ensure the quality of soldering, it is necessary to choose the right soldering flux.
