Endless electronics by R2R processing

At Fraunhofer EMFT, the latest advancements in digital lithography unlock new opportunities for high-throughput, sustainable electronics manufacturing. By combining a direct-write UV exposure system tailored for fully automated roll-to-roll (R2R) operation with a semi-additive processing approach, we enable the production of ultra-long, even theoretically endless, high-resolution metal patterns. A digitally controlled stitching technique ensures seamless alignment over extended foil lengths, expanding the capabilities of continuous electronics manufacturing.

This versatile platform supports a wide range of applications. Examples include tamper protection foils, flexible superconducting interconnects, and high-density flexible cables for medical catheters. Our technology further allows assembly and integration of packaged or bare die components via advanced bonding methods. We seamlessly combine printing, digital lithographic patterning , and precision integration techniques to deliver adaptable solutions tailored to specific functional and industrial demands.
