Nov 13, 2014 | Gregor Langer, Markus Leitgeb - Austria Technologie & Systemtechnik AG, Johann Nicolics, Michael Unger - Vienna University of Technology, Hans Hoschopf, Franz P. Wenzl - Joanneum Research Forschungsgesm.b.H.

With increasing power loss of electrical components, thermal performance of an assembled device becomes one of the most important quality factors in electronic packaging. Due to the rapid advances in semiconductor technology, particularly in the regime of high-power components, the temperature dependence of the long-term reliability is a critical parameter and has to be considered with highest possible care during the design phase (...)

The aim of this paper is to give a short overview about standard thermal solutions like thick copper, thermal vias, plugged vias or metal core based PCBs. Furthermore, attention will be turned on the development of copper filled thermal vias in thin board constructions......
