Evaluierung der Einsetzbarkeit des lasergestützten Verfahrens zur selektiven Metallisierung für die Verbesserung passiver Intermodulation in Hochfrequenzanwendungen

Description

By using the LDS® method, devices or components with excellent properties such as high integration density, design and circuit layout flexibility can be produced. These advantages are important for many applications, including the production of RF components. However, the performance of such RF components must be qualified by fulfilling some certain requirements. Passive Intermodulation (PIM) as one of key requirements of RF component performance is a growing challenge in the past recent years, which can influence the transmission quality.

The investigation carried out within the scope of this thesis reveals that both the PIM level and quality features are dependent on laser process parameters. They can be controlled within a certain range by setting suitable laser process parameters. Results presented in this thesis show that the LDS® method can be applied for the production of RF components, taking into account PIM as a performance requirement.
