Brief Abstract:
Additive manufacturing on nontraditional surfaces urges new design and fabrication techniques. Direct Ink writing often requires smooth printing surfaces and protection from abrasion and corrosion. This research describes methods for spraying and extruding RF compatible polymers to produce level surfaces and encapsulations. Additionally, with the increasing demand for rapid prototyping in RF electronics, there exists a similar need for integration of more compact IC packages in printed additive electronics. Additive manufacturing enables faster design cycling while advanced flexible substrates enable new compact geometries. To meet these needs, expanding the capabilities of additive manufacturing techniques is necessary. Developed methods and materials have shown increased stability and resilience on flexible heterogeneous circuits utilizing modern IC package technology.
