Electrophotographic Direct-Write for Electronics

摘要

Electrophotographic direct-write is a technique that has been developed to directly pattern dry powder images to a substrate. These powder images can then be fused to create the components and interconnects of an electronic circuit. Concepts of electrophotography were used to envision a new direct-write system capable of printing conductive and resistive powders. This system was developed into a test bed to conduct investigations on the feasibility of this technique. Initial experimentation was conducted to prove the system could work with both conductive (nickel) and non-conductive (oxidized copper) dry powders. With the successful patterning of these powders, testing was done to improve the quality of the printed image and increase the printed powder density.
