University Of Stuttgart & KIT Test Delta Printing And XTPL Tech For New Application

We are thrilled to announce that the Delta Printing System and XTPL Ultra-Precise Deposition technology were recently tested for a new application by our partners from the University of Stuttgart and Karlsruher Institut für Technologie (KIT). 

A team of scientists led by Martin Roemhild, Holger Baur, Norbert Fruehauf from the Institute for Large Area Microelectronics, and Georg G. and Thomas Zwick from the Institute of Radio Frequency Engineering and Electronics (IHE) collaborated to investigate the fabrication of coplanar waveguide (CPW) transmission lines using ultraprecise deposition (UPD) in the D-band (110-170 GHz). 

Their findings are detailed in the "Ultraprecise Printing of D-Band Transmission Lines" report, which concluded that UPD printing is capable of achieving a lateral precision in the order of 1 µm, making it a promising technology for producing CPWs with low losses (1.0-1.2 dB/mm at 140 GHz on fused silica) and high performance in the D-band and other high-frequency applications. This highlights the potential of UPD as an alternative fabrication method for compact RF transmission lines above 100 GHz. 

We extend our warmest congratulations to the entire team for this outstanding achievement. To learn more about their research, please read the full article.
