Abstract
A method of forming high definition elements, such as conductive traces on electronic devices or substrates, from or including viscous material. The method includes inverting the electronic components or substrates after the viscous material is applied and maintaining the inverted orientation until the viscous material dries or cures enough to maintain definition of its perimeter and edge characteristics.
Claims11
A method of forming at least one conductive trace on a substrate, comprising:
- depositing a viscous conductive material on a substrate in a pattern of at least one conductive trace;
- inverting the substrate such that the viscous conductive material is suspended below the substrate;
- and
- suspending the viscous conductive material below the substrate until the viscous conductive material obtains a defined lateral boundary that is substantially resistant to flow.
