| description | Solid lines are essential to enable printing of conducting tracks for various
electronic applications. In the flexographic printing process, the behaviour of the
printing plate plays a vital role in how ink is printed onto the substrate as it
deforms when passing through the printing nip. This deformation is dependent on
the material properties of the plate, the geometry of the lines and the pressure
within the printing nip. These will influence the printed track width and the ink
film thickness, which will affect the electrical performance of the printed
conductors. This thesis will focus on experiments on Flexographic printing
capabilities in printing ultra fine solid lines. The development of a measurement
technique which leads to successfully capturing the printing plate line geometry
details through the application of interferometry techniques, will be demonstrated.
This information is used in a Finite Element models to predict the deformation
and consequent increase in line width using both a linear and non linear material
models, the latter being based on a hyperelastic representation. A series of
experiments on a bench top printer and a web press machine to determine the
capabilities and the limitation of the Flexographic printing process in printing fine
solid is also presented. Through the experiments conducted the link between the
IGT-Fl printer and an industrial scale web press machine has been established
where the success in study on certain printing parameters and its affects lead to a
successful prints of 50ym line width with 50pm line gaps. The experiments also
point the importance of light engagement pressures within the printing train and
the requirements for using anilox cylinders having fine engraving. The work also
shows than process parameters (eg, contact pressures) that are important for graphics printing have a similar effect when the processes is used to print fine line
features
