One of the present trends in microelectronic is the embedding of electronic devices directly into structural components. This integration of smart systems into hybrid and light weight structures also is a main objective of MERGE, the research cluster of excellence on Technologies for Multifunctional Lightweight Structures. The integrated silicon sensor system, also called stress monitor chip system...
This paper presents a systematic study of sintered silver. In order to investigate the correlation between processing conditions, microstructures, thermal and electrical properties, sintered silver samples have been prepared in 27 variations of sintering temperature between 200°C and 270°C and sintering pressure between 5 MPa and 25 MPa. For the thermal and electrical characterization, the innovative...
The fracture strength of poly-silicon as widely used membrane material in micro electro mechanical system applications has a critical impact in respect to design, function and reliability of e.g. pressure sensors or microphones. This circumstance necessitates the investigation of the fracture strength of these poly-silicon membranes. In this study the strength was investigated by experimental tests...
The steady state method is a commonly used and in principle simple way to measure thermal resistance and conductivity of thermal interface materials (TIMs). The sample must be positioned between a hot and a cold plate with constant temperatures, whereby a heat flow through the sample and temperature gradient across the sample are generated. To determine the thermal resistance of the sample the heat...
In this paper, an accelerated and cost-effective characterization method for bi-material interfaces under cyclic loading using a Miniaturized Cyclic Mixed-mode Bending (MCMB) test setup is presented. The Modified Single Leg Bending (MSLB) samples are acquired directly from production-line Thin Quad Flat Package (TQFP) which provide a mixed-mode I + II loading condition. Under sub-critical cyclic loading,...
