Description

Mild Rosin Soldering Paste for Metalworking

 

This solder paste belong to a high viscosity and high-quality alloyed powder and resinic pasty flux, which will pale yellow residue. The rosin solder flux paste is widely used in phone motherboard, PC BGA to weld, solder and unsolder. The rosin paste cleans and prevents metal oxidation which allows solder to create strong, long lasting mechanical and electrical bonds.

 

How it Works

Prep Surfaces

Prep 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 Applicator

Various 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 Paste

Using 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 Solder

Apply 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.

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 this, 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.

  • 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.

 

Specifications:

Material Rosin Neutral PH 7 ± 0.3
Viscosity 1 Pa S 10 g Size 50 x 50 x 12 mm
Granularity 1um 50 g Size 75 x 75 x 17 mm

 

Method of Use:

  1. Using the end of a match or toothpick, apply a little soldering paste to the leads which need to be soldered.
  2. Placing the soldering iron tip over the leads. Making the solder against these leads.
  3. Heat the solder till it flows freely, then move the soldering iron and solder away in a rapid speed.
