  • BEEYUIHF #7142 solder flux paste has a high viscosity, similar to butter in appearance, and contains rosin, which makes the solder and the soldering surface fully moisturized. The use of flux paste can greatly improve the soldering process and efficiency.
  • Soldering recommended soldering iron operating temperature: 210-230 ° C (410-446 ° F), when we are soldering, soldering flux will be melted than the solder material first, quickly covered in the solder surface, so that it plays a role in preventing the oxidation of the metal surface, and can be at a higher temperature and the surface of the oxidized film of the reaction of the surface of the solder, so that it is melted, to restore the pure surface of the metal.
  • Solder paste flux prevent re-oxidation of surfaces during soldering, reduce solder surface tension and improve soldering performance. #7142 The primary function of flux is to remove oxides from the surface of the solder and the base metal being soldered to achieve the necessary cleanliness of the metal surface.
  • Semi solid soldering paste flux is not easy to pour, produces a stronger connection - Flux allows the solder to bond properly over the entire target area.
  • Solder paste flux in paste form reduces the temperature required for soldering, minimizes thermal deformation and stress in the soldered metal, and improves the strength and reliability of the soldered joint. In order to ensure the quality of soldering, it is necessary to choose the right soldering flux.



Product Description

BEEYUIHF Lead Free Rosin Solder Flux Paste for Electronics soldering #7142

flux for soldering

Use rosin flux paste to remove the oxidized layer on the surface of the material and increase the success of soldering. Additionally, rosin flux helps tin to increase its wettability and increase the robustness of the solder. Rosin flux is an essential soldering product.

Solder paste for electronics Insulation - Non-Conductive - Increases Fluidity

no clean soldering flux

The role of rosin flux is to reduce the oxidized solder to ensure the fluidity of the solder, rosin will be oxidized or evaporated during the soldering process, and will not affect the conductivity. Tin can be automatically returned to the place of soldering to ensure the integrity of the solder.

#7142 Flux Paste - Medium Viscosity

Warn: Please keep out of the reach of children ! ! !

How to use the solder paste flux: Please apply the solder flux paste on the pins of the components that need to be soldered, and then solder directly with a soldering tips, this is the best way to solder, which can maximize the activation of the flux activity and wettability, and improve the quality of soldering. After soldering, rosin flux can form a protective film on the surface of the components, and will not corrode the circuit board and components.

Application of Soldering Paste Flux in Repair:

 rosin soldering flux

Apply flux evenly to the pins

flux for soldering helps to separate and evenly tin the pins, making them shiny and full.Excellent wettability, non-conductive, non-sticky residue.

flux for soldering

Electronic Flux Paste

Non-corrosive to ICs and PCBs, easy to solder, quick to clean. Rosin has a low corrosivity, is neutral and does not corrode circuit components.

BGA solder and repair

The role of flux in BGA soldering: Removal of oxides "and" reduction of surface tension of the material to be soldered

flux for soldering

halogen-free, acid-free

Halogen-free soldering flux paste. Moderate viscosity, ideal for soldering wires, removes metal oxide film and increases tin wettability.

Halogen-free and acid-free, does not corrode components and circuit boards.

flux for electronics

Flux paste viscosity moderate, flux is a solder alloy wetting agent, can be contained within the surfactant, increase the wetting of tin, in order to promote the flow of solder, improve the quality of soldering, increase the brightness and firmness of the solder joints.

Solder paste flux No deterioration, good immersion, good insulation

Great product, I looked for a good flux for a long time. Many of them didn't work out for me. But this product is exactly what I need. I solder MANY MANY wires in an automotive shop. Great product for wiring harnesses. And overall soldering

Like the title says idk much about flux as I'm just learning however I use to use flux for copper water pipe but that was 20yrs ago.It's very sticky, hard to use a brush, can't use a qtip but seems to work . There's a lot here

I am a beginner when it comes to solder mostly fixing solder breaks on electrical boards for my kids, occasionally patching in a jumper to go around a burned out a PCB path. I wanted to start using resin to help the solder flow and stick better then just heat (after all, all the folks on you tube use it). I had some success with resin, but it seemed liked I used a lot and the solder was not as smooth as I thought and was hard to get on the actual piece. I suspect it is not the resins fault but my fault for not knowing what I am doing. Overall, I am very happy with the Resin.

This solder flux paste works really well! I've been using it for some electronics repair projects, and it definitely makes soldering easier. It helps the solder flow smoothly and creates strong, clean connections. The paste is a good consistency and easy to work with. It cleans up easily too, which is a plus. The container is a good size and will last me for a while. I'm not a professional, but this flux seems to be just as good as the higher end brands. I'm really happy with it.
