The objective of this master’s thesis was to create a CAD library for printed passive components. An electronic system consists of electronic components. Designing an electronic system with CAD software starts with selecting electronic components, which are the elements in a CAD library. Traditional electronics have good support from CAD software, and its electronic compo-nent libraries have rich content. Printed electronics are a new research and engineering area. However, CAD libraries for printed electronics lack content. Designing electronic systems with printed electronic components, but without support from the CAD libraries has a big challenge. The aim of this thesis is to try to find a solution by creating a CAD library for printed passive components.
Theoretical research and tool selection are necessary prerequisites for creating a CAD library. First, this thesis introduces the meaning of electronic components and the difference between active and passive components. The working principle of passive electronic components are described, especially resistors, capacitors, and inductors. Then scientific publications are sum-marized to find manufacturing methods, materials, and equipment for the printed passive com-ponents. During the literature research, important geometrical and electrical parameters for creat-ing CAD libraries are recorded. After all theoretical studies, the software tools which are used for creating CAD libraries are selected. Their features and application areas are discussed and com-pared in a wide range.
As the kernel of the thesis, a process for creating library components is described. It demonstrat-ed step by step to create a resistor in KiCAD and a capacitor in Altium Designer. Fusion 360 is used to create the components’ 3D model. The processes in this three software represent the process of creating a CAD library for printed passive components. By using the same process with different electronic components’ parameters, the library’s content can be extended. In the end, as verification, a simple RLC circuit was demonstrated by using a newly created CAD li-brary.
This work shows a solution to create a CAD library for printed passive components. However, Scientific research and engineering development are still ongoing. New printed electronic com-ponents appear every year. Libraries need to be maintained as the number of components in-creases. This could be the research and engineering area for the future.
