Why is flux important in the soldering process?

Soldering without flux is similar to brushing your teeth without toothpaste- you can do it but it probably won’t leave you with very pleasant results. Flux plays a crucial role in the soldering process. It spreads onto the soldered metal, keeps the surface clean while the molten solder alloy reaches it, and helps the solder spread over the metal. The application of flux is made easier by using a flux pen, giving you more control of the amount of flux you wish to use.

This is where the new Kester Select-10 Flux Pen on GoKimco comes in, keeping you smiling all Kester Select-10 Flux Penday long because you enjoy properly melting metals together just like you enjoy your pearly white teeth since you use the best flux- err, toothpaste- every day.

But first, what is Select-10? This is a zero-halogen, no-clean liquid flux. The makeup of the flux makes it great with challenging applications such as reflowed copper OSP boards or with difficult-to-solder components. It doesn’t spread beyond the spray pattern and it won’t clog the fluxer head. The residues are non-tacky and non-corrosive. This flux has the ability to provide desired hole-fill with preheat temperatures of 135 degrees Celsius with no clogging.

The Select-10 Flux Pen is an inexpensive addition to your work space that will make a world of difference. Being a no-clean pen, there is no cleanup necessary after its use. The pen provides good solderability under air atmosphere and is compliant to GR-79-CORE, the requirement criteria for its physical design.

The Select-10 Flux Pen was just added to the GoKimco catalog, so make sure to go check it out! GoKimco is a proud seller of a number of Kester products and we are especially excited about the addition of this one. Kester is a leading global supplier of basic and high-tech attachment materials for the electronic assembly, component and microelectric marketplaces.
