3D manufacturing process enables more rational electronics production
Chips must be well covered so that they are protected from environmental influences. At the same time, the right housing must ensure functioning contacts with the outside world. With a new technology, housing and contacting of the components can be produced individually for the respective application purpose.

Why do electronic components always have to be soldered to a printed circuit board? Couldn't these components be integrated directly into the chip housing instead? Tobias Tiedje, a scientist at the Technical University of Dresden, asked this question. With his team, the scientists developed a manufacturing approach that saves around half of the usual process and design steps and at the same time better copes with the current challenges of high data transmission, cooling and miniaturization. The most varied types of components and molded parts as well as structures (cavities and microchannels) can be used. They called their new technology KONEKT ("Contacting of embedded components as a technology solution").

KONEKT revolutionizes the production of electronic and microtechnical assemblies by using 3D manufacturing technology. The aim is to combine the advantages of mass production with the flexibility of individual production. Simplified processes enable fast and automated production of optimized assemblies through the high-frequency connection of the respective components. At the same time, process, energy and material costs are significantly lower.

This gives medium-sized companies in particular the opportunity to establish new business fields through rapid electronic manufacturing or the production of individual assemblies without high set-up costs. "With KONEKT, a wide variety of products can be realized in production," explains team leader Tobias Tiedje. "From 3D sensor assemblies as prototypes to RFID and high-frequency assemblies in series for the Internet of Things (IoT). The new technology offers users many design options without restricting their creativity".
