What is the density of the soldering flux?
On the flux density due to flux for different products.But usually between 0.79-0.93.
The flux density is an important index to control the flux for welding, the welding PCB surface should be coated with flux, in order to ensure the process effectively, must strictly control the flux density.Soldering flux is an auxiliary material that must be used in welding. An active substance that removes the oxide of solder and the surface of the base metal and enables the surface to achieve the necessary cleanliness. It can prevent the surface re oxidation during welding, reduce the surface tension of solder and improve the welding performance. Soldering flux is usually a mixture of rosin as the main component. It is an auxiliary material to ensure the smooth progress of welding process. Welding is the main process of electronic assembly, and soldering flux is the auxiliary material used in welding.
The density of rosin based flux is generally controlled at 0.82 - 0.84g/cm3; the density of water soluble flux is generally controlled at 0.82 - 0.86 g/cm3.
