Abstract
The density (and hence thickness) of a functional ink layer (41) as comprises a part of an active printed electronic component (71) is determined through interaction (13) of the functional ink with light. This information, in turn, facilitates assessment (14) of the likely corresponding electrical performance of the electronic component. When the functional ink comprises a transparent material, a dye can be added to facilitate the desired interaction and assessment.
Claims23
A method comprising:
- providing a substantially visually transparent functional ink having a dye mixed therewith to provide a dyed functional ink;
- using the dyed functional ink to form an active printed electronic component.
A functional ink comprising:
- at least a first electrically functional component, which first electrically functional component is substantially visually transparent;
- a dye.
A method comprising:
- providing a functional ink;
- using the functional ink to form at least a portion of an active printed electronic component;
- causing an interaction between light and the functional ink;
- using the interaction to assess likely corresponding electrical performance of the active printed electronic component.
