The composition and thickness of surface oxide of solder particles has a direct effect on adhesion and electrical resistance of soldering joint and resultant the quality of interconnect and the reliability of packaged system. Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and scanning transmission electron microscopy (STEM) were used...
Considering basic characteristics of moving objects, like temporal, spatial, multi-dimensional, massive, the paper proposes approach to spatio-temporal data modeling for moving objects data management, which represents in the model abstract data types and processes, dynamic attributes, spatio-temporal topological relationship, and spatio-temporal operations. It also presents how to use the model for...
