Description: From the manufacturerAppearance of the FluxSRA #135 flux is an amber colored paste. The consistency of the flux should not be gooey or hard to puncture. In other words it should be solid but also easy to dip wires and applicators into. If you see crystallization (rosin hardening) at the surface of the flux this is absolutely normal and NOT an indication of expired or tampered with flux.SKU: FLS135AboutSRA #135 is a petrolatum-based soldering flux, containing Rosin and organic acid activator. Unlike many paste fluxes, it contains NO Zinc Chloride or Ammonium Chloride, making it ideal for electrical and electronic repairs. The Rosin also leaves a protective coating over the soldered area that can prevent corrosion.Ideal for electrical and PCB repairsDoes not need to be cleanedContains 2 ounces (56.6 grams) in a jarType RA (Rosin-Activated) FluxActive Temperature Range: 93 – 315°C / 200 – 600°Dimensions: 2.5″ Dia x 1″ H (64 x 25.5 mm)Weight: 2.5 Oz (70.8g)Made in USAFlux ComparisonSoldering without flux is like trying to put a new registration label onto your license plate without first wiping off the layer of dirt and grime that has accrued on your license plate since last year. The surface needs to be clean so the adhesives on the label can do their job.Why Use Flux?because solder cannot bond without it!In order for solder to do its job, the layer of oxides on the metal surfaces you're soldering must be removed. A good flux, like #135, removes the oxides and sets the stage for soldering. The solder follows the flux, as if the flux were clearing a path for the solder and telling it where it to go. For many soldering applications, using only flux-core solder wire is sufficient. However, there are benefits of adding an externally applied flux such SRA #135, these benefits include:More control over where the solder will travel – Wherever you apply the flux, the solder will flow to.Expedites the soldering process – It takes less heat and time to get the solder to flow where you need it.Results in a stronger connection – The flux allows the solder to bond properly throughout the target area.Protects the solder joint – This rosin paste not have to be cleaned off after soldering and the residue actually provides a protective coating from corrosion.How it WorksPrep SurfacesPrep the surfaces by removing any dirt, rust, grease, paint, and other contaminants with sandpaper, wire brush, steel wool, etc. For many applications, the residues can be removed with just a rag and some isopropyl alcohol. These impurities may prevent solder flow so it is important not to proceed until clean metal is visible.Choose an ApplicatorVarious tools can be used as an applicator for the flux including toothpicks, acid brushes and spatulas. Wires and components can simply be dipped as well. One of the benefits of paste flux opposed to liquid is that it will stay put wherever you apply it.Apply the Flux PasteUsing your applicator of choice, apply the flux to the target areas you are about to solder. The exact amount applied will depend on the job but in general use just enough to cover the area to be soldered in an even coating. Remember that the solder will flow to where the flux is so make sure to apply only where it is needed to prevent solder bridges and mess.Apply Heat and SolderApply heat using a soldering iron or hot air gun to bring to melting temperature and solder. Remove heat and allow to cool. Remove residue with rag if wanted.
