Technological requirements for portable thick film hybrid devices

This paper primarily comprises excerpts of the work done under our regular undergraduate teaching program. The material is organized into subject groupings with the intention of presenting in convenient form sufficient information for making high quality thick film portable devices. The work emphasizes problems and methods of solving the construction of a thick film digital wrist-watch prototype, using a new PtAg. ink and a novel procedure to fabricate thick film multilayer structures with unusually high line densities associated with increased yield as compared with previously known methods.
