Flow Simulation of Cleaning Media in Narrow Gaps Under Electronic Components


Removing chemically active solder residues from micro-gaps challenges cleaning processes and media.
The objective of this study was to better understand how fluid mechanics influence the cleaning of gaps between components. To this end, external and gap flow simulations were established and the results were validated by laboratory testing. The media used in the cleaning process and the role of their material properties were considered separately in these simulations.
