02.12.2020, 14:00 - Low-inductance packaging concepts and capacitors in power electronics

This webinar will focus on the challenges of low inductance packaging and capacitors, especially when using modern fast switching power semiconductors such as silicon carbide (SiC) Mosfet and gallium nitride (GaN) switches. The importance of parasitic inductance is first discussed and ways and design criteria to reduce it are presented. Subsequently, different capacitor technologies are presented and the respective advantages and disadvantages are discussed depending on the application conditions.

Speakers:

• Prof. Toke Franke | University of Southern Denmark

• Prof. Thomas Ebel | University of Southern Denmark

28.10.2020, 14:00 - Rapid Prototyping: How To Satisfy Your Customer in 24h

Speakers:

• Marius Strack | VP Operations @ UniverCell

• Dr. Andreas Würsig | Deputy Head of Business Unit "Power Electronics" | Head of Group "Battery Systems for Special Applications" | Fraunhofer ISIT

 

From new ideas to finished prototype within 24h

In our increasingly fast-paced world, quick adaptations to specific customer needs are essential to differentiate from the competition. With the multitude of processes in the manufacturing industry, this is not easy. It has often been forgotten to "just do it". In this webinar, we give three concrete tips on how to win over customers with customized solutions in the shortest possible time.

21.10.2020, 11:00 - Applications and use cases of powder technology

The webinar focuses on various use cases of an innovative manufacturing technology from Fraunhofer ISIT, which was already presented in detail on September 23.

In the first part, Fraunhofer ISIT presents a piezoelectric MEMS energy harvester that converts ambient energy via magnetic coupling. In addition to its application as an energy converter, the component demonstrates the integration of micromagnets into wafer-level microsystems. The magnetic force coupling enables the use of mechanical vibrations, shocks and rotational movements even outside the mechanical resonance of the harvester as well as the coupling of energy via magnetic fields.

Another application example of integrated micromagnets are soft magnetic cores for microcoils. These serve as energy storage for voltage converters in power supplies or end devices such as smartphones, IoT applications, smart homes and other applications. ISIT's powder technology enables a wide range of coil core geometries for a variety of coil designs.  Experimental results of a voltage converter prototype with 15W power based on a microcoil and a GaN FET will be presented. This combination enables switching frequencies in the double-digit MHz range.

Fraunhofer IZM presents latest developments for the integration of corresponding microelectronic components. The implementation of through-silicon vias (so-called TSVs) enables backside contacting of sensors as well as 3-D integration of ICs or Si-based interposers for high-density wiring carriers for e.g. chiplets. The interposer platform can also include passive thin-film devices such as coils and resistors, making it ideal for SiP (system-in-package) heterointegration. Examples of this will be presented in the webinar.     

Speakers:

·Dr. Björn Gojdka, Group Manager Agglomerated Microsystems  | Fraunhofer Institute for Silicon Technology ISIT

·Dr. Michael Töpper, Business Development | Fraunhofer Institute for Reliability and Microintegration IZM

23.09.2020, 11:00 - Powder-based microcomponents - innovation building blocks of microsystems technology

Speakers:

• Dr. Björn Gojdka, Group Manager Agglomerated Microsystems | Fraunhofer Institute for Silicon Technology ISIT

• Dr. Olaf Andersen, Head of Department Cellular Metallic Materials | Fraunhofer Institute for Manufacturing Technology and Applied Materials Research IFAM

Fraunhofer ISIT presents a new, patented process for manufacturing and integrating three-dimensional microcomponents at wafer level. Numerous manufacturing parameters allow the generation of microcomponents with defined magnetic, thermal, optical, and electrical properties and freely designable geometries of a few tens to thousands of micrometers. A central process of the powder-based method was developed by Fraunhofer IFAM, Dresden branch, which has many years of expertise in powder metallurgy and in the field of porous metallic materials. IFAM presents possibilities for the characterization of powder materials and porous structures using accredited methods, among others. A patent-pending multifrequency process for transporting and uniformly dosing ultra-fine powders will be presented, which is currently being used and further developed for filling cavities on silicon wafers.
