Wettability as a surface property has a great effect on the droplet spreading on substrate. The droplet motion control on surface can be achieved by combining hydrophobicity and hydrophilicity regions on substrate surface. And the possibility of using the heterogeneous surface formed by appropriate hydrophobic regions to guide the droplet spreading or splitting along certain directions has recently...
Recently, active cooling system is strongly needed in high heat flux density microelectronics. Micropump is the essential component in the active cooling system. In this paper, a mechanical micropump is proposed for electronic cooling with a 2L/min flow rate, 90KPa pressure head at 22000 rpm (revolutions per minute). The overall size of the micropump prototype is 43mm in width and 65mm in length....
Multi-physics multi-scale modeling issues in various stages of the LED manufacturing, 3D-SiP, and nano interconnects have been discussed. Molecular dynamics (MD) and finite element method (FEM) have been used to study the scale effect of the material properties and the prediction of the module behaviors which are critical to LED fabrication. We propose a new concept to integrate multi-physics/multi-scale...
