Rough condition? Tough ceramics!
For more than 30 years, Fraunhofer IKTS has been demonstrating the potential of ceramic materials. We develop electronic components that are suitable for use in harsh environments with high thermal, chemical and/or mechanical loads.

J.A.M.E.S Coin NFC On AME In 3D Ceramics
For the first time the J.A.M.E.S Coin Design is transformed into a new material and process concept. The Fraunhofer IKTS at Dresden used their process knowledge in additive ceramics to realize the NFC
Simultaneous Manufacturing And Co-Sintering
To allow the integration of the functional materials also inside the component, which results in a higher degree of freedom concerning the design, simultaneous manufacturing is used.
Competence in Additive Ceramics
For more than 30 years, Fraunhofer IKTS has been demonstrating the potential of ceramic materials. We develop electronic components that are suitable for use in harsh environments with high thermal, chemical and/or mechanical loads. Additive processes are used for complex geometric requirements. Thick-film and direct-writing technologies can be used to functionalize the components. For this purpose, layers of sensory or actuator active, electrically conductive, thermally conductive and/or insulating pastes or inks are applied and sintered.
Ceramics as High-Frequency Circuits
For the manufacture of high-frequency assemblies, all-ceramic or glass-ceramic LTCC materials with their outstanding high-frequency characteristics provide the springboard to the next generation of circuit carriers. LTCC ceramics can be functionalized comparable to printed circuit boards with electrical conducting tracks and provided with internal functional layers or buried structures.
We cover the entire value chain: from material synthesis and powder processing to the development of functional ceramic semi-finished products, component and system design, and process development, right through to functional testing and reliability studies. In the area of AME, the development of customer-specific functional inks/pastes, as well as technology development for 3D metallization and integration, form the main focus of work. For our customers, we can map various scales, ranging from feasibility studies to the development of small series for demonstration purposes to the transfer to mass production.
HYDRA - Hybrid approach of thick-film and laser direct structuring for functionalization of 3D-ceramics
HYDRA is an AiF project approach focusing on novel metallization concepts for 3D-AME ceramics. In that way, very fine and high-power conductive paths can be realized on 3D-AME ceramics. This enables completely new design possibilities for highly robust ceramic substrates. Fraunhofer IKTS, Hahn Schickard and IFKB Stuttgart are working on a technology combination of thick-film and laser direct metallization of 3D-AME ceramics. Both technologies will be evaluated on 3D-AME ceramics in terms of printing accuracy, electrical and reliability characteristics, including a detailed analyses of interconnectability of both metallization types.
Thick-film technology on 3D-substrates did not reach fineline resolutions like in standard screen-printing processes but offers excellent packaging characteristics. Laser direct metallization of ceramics offers very high line resolutions but only limited interconnection characteristics. Therefore, a combination of both technologies on the same substrate will be addressed to overcome the single disadvantages and generating 3D-AME ceramic substrates with fineline and high power conductive paths on the same surface.
The project is realized on industrial machines but needs a comprehensive expertise of different market participants. Therefore, are we currently looking for advisory committee partners from the field of AME production, engineering, electronic components or sensor manufacturing and material development or supplier. We kindly invite you to bring in your expertise to improve the development process and reaching next technology levels together.

The combination of ceramic additive manufacturing and thick-film as well as direct-writing technologies opens up a wide range of new applications for harsh environments
Additive manufacturing has high innovation potential for ceramic products in terms of design and the ability to produce novel composite and gradient materials.
While additive processes offer new possibilities through their principle, the combination with established thick-film and direct-writing technologies further expands the spectrum of functions, components and applications.
A wide range of packaging technologies such as soldering, bonding, welding, wire bonding or sintered assembly are available for electrical contacting and the assembly of other electronic components.
The technology combinations presented pave the way for manufacturing applications in electronics and power electronics as well as sensor and energy technology.
