Superior Flux Products

Electronics Soldering Flux

Electronics soldering flux is used in soldering applications in printed circuit board (PCB) assembly and rework; component lead tinning; and wire tinning. Soldering is a process whereby similar or dissimilar metals are joined using a soldering alloy that typically includes tin combined with lead, silver, copper, antimony, bismuth or indium.

Surface Mount (SMT) Solder Paste

Superior Flux offers a full range of solder pastes for SMT reflow applications, including: conventional and low-residue No-Clean, water-soluble (including a water-soluble RMA), and low temperature formulations.

Industrial Soldering Flux

Superior Flux & Mfg. Co offers a long line of Industrial Flux and Electronic Flux that available from A to Z. Industrial Soldering Fluxes cover soldering operations that are non-electronic. (In contrast to Industrial Soldering Flux, Electronic Soldering Flux is used in printed circuit board (PCB) assembly and repair, and component lead tinning.)

Brazing Flux

Brazing is a process whereby similar or dissimilar metals are joined using an alloy that often includes a base of silver combined with nickel, copper and zinc. High temperature brazing, generally used for carbide products, may employ alloys that contain no silver but use nickel, copper and manganese.

Welding Flux

Welding is a metal-joining process whereby similar metals are joined using a direct heat source to melt the base and filler metals to create a uniform finished product.

Automotive Flux

Automotive fluxes are used in a variety of processes from soldering radiators, batteries, electronics and wire harnesses to general brazing, and welding muffler tubes or other repair work. These fluxes can be used in different heating situations, such as dipping parts into molten solder, hand feeding alloy, induction or conventional heating.

Aluminum Flux

The use of aluminum in industrial and electronics applications is increasing dramatically. Aluminum is abundant and considerably cheaper than metals such as copper. Aluminum also has inherent advantages, such as lightness and corrosion resistance.
