60 SMT Magazine • April 2015 A number of the piezo actuation profiles suggest that there is a slight decrease in satel- lite level for smaller droplet volumes. In the context of these jetting experiments, satellites are primarily formed during the break-off pro- cess and not as a result of impact splashing [6] . A possible explanation for this behavior ties the increase in positioning deviation with the decreased production of satellites. The speed of the fluid during break-off will scale with the mass of the droplet, such that a small- er droplet will have a lower speed.
