Flow behavior

Flow behavior refers to the ability of a material, particularly solder, to spread evenly across a surface under the influence of temperature and flux. It describes the viscosity of the solder and how well it can wet the joint to create a stable and homogeneous bond. The flow behavior is influenced by the flux, which removes surface oxides and reduces the viscosity of the solder, allowing it to better penetrate the joint. Good flow behavior is crucial for the quality and durability of the soldered connection.
