Main highlights

The most prominent role of # 8403 flux is to remove oxidation, soldering flux is a kind of chemical substances to promote soldering, have the surface of the soldering material oil to remove oil, remove the oxide layer, increase the role of the soldering surface. Flux paste also has the task of protecting components and preventing reoxidation. Flux is an indispensable auxiliary material when soldering and repairing to achieve better soldering and repair results.
The main function of #8403 solder flux is to reduce the surface tension caused by the contact between the solder and the metal of the pencil, increase the wetting force of the surface and improve the penetration of the organic activator, which is the key role of the flux. Flux paste is fine and white, with very little residue, and can achieve the performance of no clean.
How to use electronic flux: wipe the electronic components and their circuit board clean before soldering, press the right amount of flux on the surface of the components or wire, heat the soldering iron to 200 °C or more, and then the tin will be melted in the solder. After adding flux, it is very easy to put on the tin, and the structure of the solder joint is very full and strong and bright.
BEEYUIHF #8403 is made of no clean, halogen-free, acid-free, non-corrosive flux, white paste, good flowability, moderate viscosity, less residue, less smoke, suitable for mobile phone PCB, BGA and PGA and other SMD ball array solder joints rework and ball patching.
#8403 soldering flux paste product applications: applicable to sensors, wires, motors, fuses, connectors, metal shells, lighting, electronic components, SMT repair, BGA chip ball implantation, etc.
