How do you confirm the spray status of the soldering flux?
Is soldering flux used for wave soldering? If it is, visual inspection can be, and then according to the tin after the furnace to be adjusted to achieve the best results
The state of atomization mainly depends on the flame color of the torch flame. Besides, the seam sealing state of the weldment surface is smooth, plump and so on.
Spraying is the latest method of flux coating, which is most suitable for coating without cleaning flux. Because the flux is placed in a pressurized container through the nozzle spray mist flux coating on the surface of PCB, injectors, degree of atomization and spray width can be adjusted, so it can accurately control the amount of solder coating. Because the coated flux is a foggy sheet, the solder on the plate is very uniform, ensuring that the welded panels meet the requirements of cleaning. At the same time, due to the flux completely sealed in the container, does not need to consider the solvent evaporation and absorption of moisture in the atmosphere, which can keep the flux proportion (or components) unchanged, once added to run out before without replacement, a foaming method and wave method can reduce the amount of flux is more than 60%. Therefore, spray coating is the preferred coating process in the cleaning process. In the spray coating process must pay attention to a little, because flammable solvent containing more flux of solvent vapor spray from the deflagration exists certain risk, so the equipment should have good ventilation facilities and necessary fire extinguishing apparatus.
