An Experimental Study of Molten
Microdroplet Surface Deposition
and Solidification: Transient
Behavior and Wetting Angle
Dynamics
The basic problem of the impact and solidification of molten droplets on a substrate is of
central importance to a host of processes. An important and novel such process in the
area of micromanufacturing is solder jetting where microscopic solder droplets are dis-
pensed for the attachment of microelectronic components. Despite the recent appearance
of a few numerical studies focusing on the complex transient aspects of this process, no
analogous experimental results have been reported to date to the best of our knowledge.
