Regional networking, research and business development

Batteries are important for the development of the energy systems of the future. They provide storage options for renewable energy sources in electromobility and smart grids. The energy density and the charging and durability properties of batteries are important. However, large-scale deployment of batteries depends on improvements in technology and cost/production:

• Materials and methods for producing stable battery cells with high energy density.
• Efficient, reliable and cost-effective battery packs suitable for customers' purposes
• Integration of battery packs into electromobility and smart grid applications and efficient charging.
  

The seminar is organized by WTSH GmbH in cooperation with Fraunhofer ISIT, Emobilität.SH, and the PE-Region Platform and gives an overview of some of the development and business activities related to battery technologies and kicks off a new regional battery forum initiative.
Participate online to explore and develop new options in power electronics.

Many monitoring, measurement and characterization tasks in industry today are based on classic ultrasonic sensors. Micromechanical ultrasonic transducers (MUTs) represent an innovative and effective further development in this context, which can open up new areas of application thanks to their compact design and power efficiency. However, the investment costs for the development of such MUTs are too high for many small and medium-sized enterprises (SMEs). Therefore, three Fraunhofer institutes are jointly developing an application platform that also enables SMEs to use MUTs. Various micromechanical components and pilot products are to be developed in cooperation with industrial partners. In a first step, workshops will be held starting in July to demonstrate the good integrability of MUTs in already existing systems.

In Germany alone, corrosion and its consequential damage cause annual costs in the billions in a wide variety of industries and economic sectors. An even higher financial damage of more than 4 percent of the gross national product arises if, in addition to the direct damage caused by corrosion, the consequential costs due to production or service failures are also taken into account. 

Therefore, in the context of this event, we will present the most relevant results of our 2-year work from the IGF research project on the "Impact of Ionic Contamination in Thin Gaps on Realistic Assemblies with New Miniaturized Devices".

In particular, we will provide you with the following know-how: (1) the latest findings on increasing product safety for the use of miniaturized electronic components and (2) the latest insights into optimizing test methods for early detection of ECM (electrochemical migration).

Explore with us methods for increased product safety for miniature electronic components!

As part of the "kurz & knackig" format of the FED Regionalgruppe Stuttgart, Helge Schimanski will give a presentation on the influence of depaneling on assembly quality on May 4, 2022. Starting from the user's requirements for depaneling methods and possible problems, different depaneling methods will be addressed.

Not only will recommended limits for the surface strain of ceramic capacitors and the consequences of damage to these components be shown, but typical damage caused by incorrect depaneling will also be illustrated by means of examples, and the measurement with strain gauges for the qualification of depaneling methods will be presented. The developer then receives tips for a design suitable for production and a depaneling process that is gentle on the components and thus adds value for the production of high-quality and reliably operating assemblies and systems.

Low-pass filtering of the pulse width modulated (PWM) output voltages of the three-phase voltage source inverter (VSI) by sinusoidal LC filters is an established solution in squirrel cage induction motor(SQIM) based adjustable speed drive (ASD) applications. This presentation discusses the several design methods of LC filter for an ASD application. It may also deteriorates the performance of the closed-loop control of SQIM because of the sustained resonancefrequency oscillations. The presentation discusses several methods of damping the resonance and its effect on the ASD.

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.
