951 Soldering pen Description:
This product is filled with environmentally friendly cleaning flux by default. If you have any other requirements, please contact me. The welding pen is widely used in the PCB / FPC board welding process. It is easy to carry and easy to operate. The welding pen is a one-time use. Wrong, do not open the added flux.
To prevent flux volatilization, to ensure that the flux characteristics of the same
If you add alcohol, help welding pen can be used for cleaning brush transparent pen, easy to understand the use of flux or detergent.
Help pen use:
1. Before welding, apply flux on the base metal (improve the wetting)
2. By applying the flux to the object at the time of correction, the wax can be removed and the wettability can be improved.
3. Alcohol and other solvents can be used to clean the substrate (prohibit the use of organic solvents)
Flux (flux): in the welding process can help and promote the welding process, but also has a protective effect, to prevent oxidation of chemical substances. Flux can be divided into solid, liquid and gas. There are several aspects such as "auxiliary heat conduction", "removal of oxide", "reduction of surface tension of welded material", "removal of oil surface of welded material, increase of welding area", "prevention of reoxidation" There are two more critical aspects of the role: "remove the oxide" and "reduce the surface tension of the material being welded."
