Applications extend to millimetre wave frequencies as low loss material systems are available. However, these modules demand very fine lines and spaces for the conductor patterns and accordingly the requirement for even reduced tolerances grows. This paper shall present the technologies available in fine line LTCC conductors to meet the challenges of millimetre wave circuits.enaerosol printingfine line conductorsinkjet printingLTCCoffset gravure printingphoto-etchedphoto-imageableresinate pastesscreen printingthin film620666conference paper
