Abstract

”The printed electronics have been broadly applied in our daily lives, many new manufacturing methodologies are studied and investigated. The research here presented the full manufacturing process of printed conductors of aerosol printing and flash sintering techniques on substrates such as planar and non-planar surfaces.

The aerosol printing (AJP) was introduced because of its simplicity in experimental setup and flexibility of printing. It produces less ink waste and consumes less manufacturing cost. Furthermore, it has the direct-write ability to print in any customized patterns or shapes on non-planar surfaces. In this study, the Cu NPs was selected as the functioning material ink because of its low cost and great cost performance. Additionally, the flash sintering was performed on non-planar surfaces while the AJP method was applied in printing on non-planar surfaces.

Conductivity ratio (the conductivity measured that is compared to the bulk copper) was calculated and plotted for characterizing the flash sintering applications on non-planar surfaces. Analysis indicated that a back reflector was needed for a uniform conductivity ratio on the surface. Simulations have been also demonstrated with experimental results in the study of applying back reflector. Results showed averaging 13% of conductivity ratio on planar surfaces and the performance on non-planar surface was 12% of that of bulk copper.

The close conductivity performance can sum up this manufacturing technique in printing conformal conductors on either surface is very alike and may potentially be used in many fields and customized manufacturing in the future”--Abstract, page iv.
