With the development trend of microelectronic system with small size, high speed, high frequency and high density, passive and active components are directly embedded into a core or high-density-interconnect layers. This System-in-Package (SiP) technology could shorten interconnection between the die and substrate and reduce the inductance and noise interference. However, there are many electrical...
Thermosetting polymers are widely used in electronic packaging. For instance, epoxy molding compound is extensively used as an encapsulant for electronic packages to protect the IC chips from mechanical and chemical hazards. It is well known that molding compounds show not only strong temperature dependent but also time dependent behavior. The thermo-mechanical behavior of these polymer constituents...
Heat based tumor ablation methods such as radiofrequency (RF) and microwave (MW) ablation are increasingly accepted treatment methods for tumors not treatable by traditional surgery. Typically, an interstitial applicator is introduced under imaging guidance into the tumor, and tissue is destroyed by heating to above -50degC, with maximum tissue temperatures over 100degC. Since high thermal gradients...
The need for a sensitive method of the non-destructive evaluation of skin layer properties is highly desirable in a number of medical applications. The use of laser-generated surface acoustic waves (SAW) for the characterisation of multi-layered materials is widely used in industrial applications. In this paper we present research expanding this principle for the use of generated SAW for the characterisation...
