Flux coated brazing rods/wires are made by applying a strong flux to the surface of a well-formed filled metal rod/wire. The attached flux is carefully selected to match the filler metal and is highly reactive, non-corrosive and non-hygroscopic. This perfect combination of flux and filler metal simplifies and eliminates the need for separate fluxing operations, greatly increasing the efficiency of the brazing process. This convenient self-adhesive rod/wire is ideal for difficult-to-contact brazed joints where it is difficult to insert flux.
Flux is usually a mixture of rosin as a main component and is an auxiliary material to ensure smooth welding. Welding is the main process in electronic assembly, and flux is an excipient used in soldering.
This flux is widely used in refrigerators, air conditioners, radiators, auto parts and tools.
Paste brazing flux

fluid-paste brazing flux/ Gas booster flux
These products are formulated to prevent molten solder metal from flowing through the surface of the part during the brazing process and allowing it to wet. They are suitable for use in vacuum furnaces, controlled atmospheres or air brazing processes. The residue in the stop section before and after brazing is preferably removed by washing with water.
The main function of the flux is to remove the oxides from the solder and the surface of the soldered substrate to achieve the necessary cleanliness of the metal surface. It prevents reoxidation of the surface during soldering, reduces solder surface tension and improves solderability. The quality of the flux directly affects the quality of the electronic product.
