NP is pioneer in manufacturing full range of soldering fluxes for various application from last 35 years . NP flux range includes halide based / halide free with low solid contents no clean type, water soluble, rosin ( type RMA ) including VOC – free no clean flux / suitable for wave , dip and spray application. Fluxes are used in soldering processes to facilitate the joining of metals by improving the wetting and bonding of solder or filler material to the surfaces being jointed. With our advanced technology we have emerged distinguished manufacturer of liquid soldering fluxes in the country. Fluxes are RoHS compliant. We also provide equivalent diluters / solvents for fluxes to maintain specific gravity.

Flux is indispensable in the soldering of electronic components and other applications. A soldering flux performs many functions, the most important of which is the removal of oxides film, other tarnished film and surface film from the metal to be soldered. It exposes clean surfaces for optimum wetting and solder ‘NP’ formation. A flux’s ability to prepare good surface for soldering is the measure of its activity. From our long and vast experience, we have constantly researched flux technology and have developed various types of fluxes, which provide unrivaled performances.

This flux is a mixture of high-quality WW resin and alcohol, having solid content between 30-40%. The excellent mobility of the flux is caused by the low surface tension. It is used where flux residue removal is not necessary or where the circuit is affected by low level current leakage. It is mainly used for wire and component lead tinning. Residue is non corrosive and meets all the requirements of MIL-standard.

NP has developed special mildly active fluxes for electronic and electrical industries where slightly active fluxes are required for foam fluxing as well as for dipping and brushing methods. The formulation of this flux has been adjusted in such a manner that even a low air pressure will produce a uniform head of foam bubbles. This flux is available in different compositions (solid contents etc).

Formulated for high speed and special soldering requirements of electrical components. This flux can be applied by dipping, foaming and spraying. The flux residue is too dry, non-sticky and non-corrosive but may require post solder cleaning in circumstances. The residue can easily be removed by using solvents.

The low solid fluxes are organic based, having very low solid contents formulated for wave soldering of multilayer, single and double-sided bare copper lacquer / OSP coated, solder plated printed circuit boards. These fluxes contain a small percentage of unique resin, proprietary activators and a special solvent system which leaves very thin, uniform and tack free transparent residues after soldering. Assemblies soldered with these fluxes have greater surface insulation resistance, thermal stability and provides excellent performance in pin testing. The residues are non-corrosive, non-conductive and non-hygroscopic, hence no post solder cleaning is required. These fluxes are available in halogen free version also. Key features of our fluxes are: fast wetting, bridge free strong and reliable solder joints, no solder balls, better thermal stability and greater surface insulation resistance. Our fluxes are widely being used in consumer, automobile, electrical, telecom and lighting industries.

These fluxes are rosin free having 1.5 to 2.5 % solid contents and are totally halide free. Due to the absence of halide and careful incorporation of organic activator system, these fluxes are safe. The small residues is nonconductive , non corrosive and non hygroscopic thus, no post solder cleaning is required. These fluxes are both effectively and popularly used in the consumer telecommunication and computer industries. These fluxes are suitable for both bare copper and solder plated circuit boards. NP WATER SOLUBLE FLUXES This flux is formulated from organic compound dissolved in a suitable solvent of highest purity. Post soldering residue is water soluble and can be cleaned by using water. These highly effective fluxes are employed for various electronic soldering applications.
