Embedding technology enables miniaturisation of electric and electronic components together with improved reliability and thermal stability in harsh environment. This work investigates in form of single case studies the environmental performance from cradle-to-gate of two new designed and fabricated power modules for electric vehicle application with the method of the Sustainable Process Index (SPI)...
This work presents environmental aspects of LED lighting systems based on existing Life-Cycle-Assessment (LCA) studies in the context of different approaches: LEDs are a lamp group consisting of various materials, properties, and packaging designs. A variety of functional units are discussed followed by detailed lighting energy statistics of Austria representative for Central Europe. LCA studies should...
The construction boom of photovoltaic (PV) plants in Europe has passed its peak. 75 % of the cumulated installed power has been built in the last three years. This work investigated share, distribution, and sizes of free-field PV plants in Europe by evaluation of manufacturer's reference data, governmental data and Google mapping. In the region of South Moravia (Czech Republic) free-field PV plants...
This publication provides the results of material characterization and binder burnout studies of the commercially available ferrite LTCC (Low Temperature Co-fired Ceramics) tape ESL 40012 used for integrated passive components in LTCC packages. The investigations comprised surface roughness measurements of the fired tape and chemical analysis of the green tapes as well as tapes fired at different...
This study provides life cycle inventory data of a small batch production of two different types of low-temperature co-fired ceramic (LTCC) substrates, HERAEUS CT 765 and CERAMTEC GC, with the main focus on the pre-using phase. A comprehensive life cycle flowchart of LTCC devices produced in a prototyping research laboratory was generated. Preliminary results of life cycle inventory (LCI) data were...
This paper discusses the European strategies and their closely related research focuses on the environmental impact of electrical and electronic products. The influence of the referencing main EC-Directives and EC-Regulations on life cycle analysis and environmental impact assessment is discussed.
We present a method of dynamic thermal characterization of an entire test assembly, consisting of high-power Light Emitting Diodes (LED) and a printed circuit board (PCB) by measuring the thermal response on a power-on-step function and describing the thermal impedance with a Foster RC network. For this purpose, we record temporal temperature functions on test assemblies during pulse load experiments...
