Conclusions:

The validated analytical model provides a robust framework for predicting liquid metal flow over rough surfaces.
The findings are applicable to optimizing solder joint formation and understanding interfacial phenomena in electronic packaging.
This study bridges theoretical modeling with experimental validation for microscale fluid dynamics.
