Multilayer Ceramic in Low Temperature Co-Fired Ceramics (LTCC) is an excellent substrate for highly integrated microwave circuits. 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.
